Mississippi librarians work across four distinct settings, from K-12 schools and public library systems to university research collections and state government agencies, and the credential requirements for each track differ sharply. A school librarian needs the 440 Library Media license from the Mississippi Department of Education, while a public or academic librarian typically needs an ALA-accredited MLIS but no state-issued license at all. That split shapes every decision you face: which degree to pursue, how long the process takes, and what you can expect to earn. With the state's median librarian salary sitting below the national figure of roughly $65,800, cost control on the front end matters as much as the credential itself.

Types of Librarian Careers in Mississippi

Mississippi offers four distinct librarian career tracks, each with its own credential requirements, typical employers, and day-to-day focus. Understanding these differences early will save you time and money as you plan your education.

School Librarian (Library Media Specialist)

School librarians in Mississippi work in K-12 settings and carry the official title of Library Media Specialist. This is the only librarian track in the state that requires a specific license issued by the Mississippi Department of Education: the Library/Media 440 license. To earn that license, candidates must complete an approved graduate program in library science and hold (or be eligible for) a standard Mississippi educator license. If you are exploring graduate options, consider browsing online MLIS school librarianship programs that align with Mississippi's requirements. Major employers include school districts across the state, from DeSoto County Schools in the north to the Biloxi Public School District on the Gulf Coast.

Public Librarian

Public librarians serve communities through county and regional library systems. Mississippi does not require state licensure for public librarians, but most systems prefer or require a master's degree in library and information science (MLIS) from an ALA-accredited program. That said, smaller rural systems sometimes hire candidates who hold a bachelor's degree, particularly for branch manager or circulation roles in areas where recruiting MLIS holders is difficult. Notable employers include the Jackson-Hinds Library System, the Hancock County Library System, and First Regional Library, which serves nine counties in northwest Mississippi.

Academic Librarian

Academic librarians work within college and university library systems. Like public librarians, they do not need a state-issued license, but an MLIS is effectively the baseline credential. At Mississippi's research universities, including the University of Southern Mississippi, the University of Mississippi (Ole Miss), Mississippi State University, and Jackson State University, academic librarians often hold a second master's degree or a doctorate in a subject area. Some of these positions are tenure-track faculty roles, meaning candidates must also demonstrate a research and publication record.

State Government and Special Librarians

The Mississippi Library Commission (MLC) employs librarians who provide statewide consulting, interlibrary loan coordination, and support for public library development. Special librarians also work in law firms, hospitals, corporate archives, and museums. Credential expectations vary widely in this track. MLC positions typically require an MLIS, while some corporate or medical library roles may emphasize subject expertise alongside, or even in place of, a traditional library science degree. Neighboring states have their own distinct credential structures; for example, Alabama librarian requirements differ notably from Mississippi's.

Quick Comparison of Credential Requirements

• School librarian: MDE Library/Media 440 license plus a valid educator license required.
• Public librarian: MLIS preferred; bachelor's degree may suffice in smaller rural systems.
• Academic librarian: MLIS required; a second master's or doctoral degree often expected at research universities.
• Special/government librarian: MLIS typically required for state roles; subject expertise may substitute in niche settings.

Choosing the right track shapes every decision that follows, from the degree program you select to the timeline and total cost of entry.

Step-by-Step: How to Become a School Librarian in Mississippi

If you want to work as a librarian in a K-12 school in Mississippi, you need one specific credential: the Library/Media 440 license issued by the Mississippi Department of Education (MDE). This endorsement certifies that you are qualified to serve as a school library media specialist, and no Mississippi public school district can hire you for that role without it. The steps you take to earn the 440 depend on whether you already hold a teaching license. If you are curious how other states handle school librarian certification, the requirements vary significantly from state to state.

Pathway for Current Mississippi Teachers

If you already have a valid Mississippi teaching license, adding the 440 endorsement is a relatively streamlined process. Here is the general sequence:

• Complete an MDE-approved library media program. You must finish coursework in areas like collection development, information literacy, cataloging, and instructional technology through a program the state has approved.
• Pass the Praxis II Library Media Specialist exam (5311). This is the required content knowledge test. ETS administers the exam, and Mississippi sets the minimum passing score.
• Apply for the 440 endorsement. Once your program and exam scores are verified, you submit an application to the MDE to add Library Media 440 to your existing teaching license.

Because you already satisfy the general teaching requirements, you can often complete this pathway through graduate-level coursework alone, without repeating student teaching.

Pathway for Non-Teachers

If you do not hold a Mississippi teaching license, the road is longer but still well defined. You will need to satisfy both the general teaching licensure requirements and the library media endorsement simultaneously:

• Hold at least a bachelor's degree. Any regionally accredited institution is acceptable, though your undergraduate major does not have to be in education.
• Complete an MDE-approved library media program that includes a practicum or student teaching component. This hands-on experience is required because you are entering the teaching profession for the first time.
• Pass the Praxis II Library Media Specialist exam (5311). The same content exam applies to all candidates regardless of starting point.
• Apply for a standard Mississippi teaching license and the 440 endorsement together. The MDE will evaluate your transcripts, test scores, and practicum hours before issuing both credentials.

Understanding the License Tiers

Mississippi uses a tiered licensure system, and the tier you qualify for has a direct impact on your salary. The tiers are:

• Class A: Requires a bachelor's degree plus completion of an approved library media program. This is the entry-level tier for school librarians.
• Class AA: Requires a master's degree in library media or a related field. Most candidates who earn an MLIS or a master's in library and information science will qualify here.
• Class AAA: Requires an education specialist degree or equivalent graduate hours beyond the master's level.
• Class AAAA: Requires a doctoral degree.

Each step up on this ladder places you on a higher rung of the Mississippi state salary schedule, so pursuing a master's degree is not just an academic achievement; it translates directly into higher annual pay throughout your career.

The Most Direct In-State Route

The University of Southern Mississippi (USM) offers a School Library Media program specifically designed to satisfy MDE requirements for the 440 endorsement. For candidates who want the most seamless alignment between their coursework and the state licensing process, USM is the primary in-state option. The program covers the competencies tested on the Praxis II and includes the practicum experience that non-teachers need. Online alternatives from out-of-state, ALA-accredited institutions can also work, but you will want to confirm with the MDE that any external program meets Mississippi's approval criteria before enrolling. Neighboring states such as Louisiana follow a similar add-on endorsement model, so candidates relocating from the region may find some overlap in requirements. You can read more about louisiana school librarian certification for a side-by-side comparison.

The Path to a 440 Library Media License in Mississippi

The most common route to becoming a school librarian in Mississippi is for a current teacher to add the 440 Library Media endorsement. Here is the step-by-step sequence from your existing teaching license to a fully endorsed, advancement-ready credential.

How to Become a Public or Academic Librarian in Mississippi

Unlike the school librarian path, Mississippi does not require state licensure or certification for public or academic librarians. There is no board exam to pass and no credential to renew through a state agency. Instead, hiring decisions rest entirely with individual employers, whether that is a county library system, a city branch, or a university. That employer-driven model means your qualifications, and especially your degree, shape what doors open.

The MLIS as the Industry Standard

An ALA-accredited Master of Library and Information Science remains the baseline credential that most employers expect. Mid-to-large public library systems across Mississippi, including Jackson-Hinds Library System and the Hancock County Library System, typically list an MLIS (or equivalent master's degree from an ALA-accredited program) as a minimum requirement for professional librarian positions. At the university level, the standard is even more firmly established: virtually every academic library in the state requires a completed MLIS for librarian roles. For a broader look at mlis degree requirements, our national guide breaks down the steps in detail.

Because Mississippi has only one in-state ALA-accredited program (at the University of Southern Mississippi), many candidates earn the degree online from accredited programs in other states. Employers do not generally distinguish between an online and an on-campus MLIS as long as the program holds ALA accreditation.

The Exception: Smaller and Rural Library Systems

Mississippi is home to dozens of small public library systems serving rural communities. Budget constraints and limited applicant pools mean these systems sometimes hire candidates who hold a bachelor's degree, occasionally in any field, for branch librarian or library manager positions. Entry-level paraprofessional roles such as library assistant or circulation supervisor frequently require only an associate degree or relevant experience.

This reality should not discourage you from pursuing an MLIS. Candidates with the master's degree consistently qualify for higher-paying positions, have more geographic flexibility, and are better positioned for advancement into directorships. If you are already working in a small system with a bachelor's degree, completing an MLIS part-time or online can open a wider range of opportunities without requiring you to leave your current role.

Academic Librarian Positions at Research Universities

Mississippi's three largest research universities, the University of Southern Mississippi, the University of Mississippi (Ole Miss), and Mississippi State University, maintain sizable academic library systems with distinct hiring tiers. If an academic career appeals to you, our guide to earning an academic librarianship degree covers specialization options worth considering early.

• Tenure-track faculty librarian roles: These positions typically require an ALA-accredited MLIS plus a second subject master's degree or a doctoral degree. Research and publication expectations mirror those of other faculty members, and the second advanced degree usually must align with a subject area the library serves.
• Non-tenure staff librarian roles: Many academic libraries also employ professional staff librarians who are not on the tenure track. These positions generally require only the MLIS, though relevant experience or a subject specialization can strengthen your candidacy.
• Library support and technical roles: Positions in cataloging, interlibrary loan, or digital services may require a bachelor's degree plus specialized technical skills rather than an MLIS, depending on the university's classification system.

If you are considering the academic route, review current postings at each university to understand which tier fits your background and career goals. An MLIS paired with a second graduate degree is also valuable in library science careers without mlis settings where information expertise transfers to adjacent fields. Planning for a second graduate degree early can save time and money if a tenure-track appointment is your target.

Questions to Ask Yourself

Mississippi Library Science Degree Programs: USM and Online Alternatives

Choosing the right degree program is one of the most consequential decisions you will make on the path to a librarian career. Mississippi has one ALA-accredited library science program within its borders, but several reputable online options from neighboring and national universities also serve Mississippi residents well.

University of Southern Mississippi: The State's ALA-Accredited Program

The University of Southern Mississippi (USM) is the only institution in Mississippi offering an ALA-accredited Master of Library and Information Science (MLIS).¹ USM also offers a Bachelor of Library and Information Science (BLIS) for students who want an undergraduate foundation in the field, though the MLIS is the degree that qualifies graduates for most professional librarian positions.

Key details about USM's MLIS program:

• Format: Fully online, making it accessible from anywhere in the state.¹
• Credits required: 40 to 46 credit hours, depending on your chosen track.¹
• Per-credit cost: Approximately $570 to $600 per credit hour (based on 2024-2025 rates), with out-of-state students paying the same rate as in-state students.²
• Total estimated cost: Roughly $24,000 to $30,000 for the full program.³
• Accreditation: ALA-accredited.¹
• 440 license eligibility: USM's School Library track is approved by the Mississippi Department of Education (MDE) and satisfies the requirements for the 440 Library Media license.¹

For aspiring school librarians in particular, USM's MDE-approved status makes it the most straightforward choice.

Online ALA-Accredited Alternatives Popular with Mississippi Residents

Several out-of-state, fully online MLIS programs attract Mississippi students. Three of the most commonly chosen are:

• University of Alabama (MLIS): Located in a neighboring state, Alabama's ALA-accredited MLIS is delivered entirely online. Tuition for out-of-state students has historically been competitive, and the program's regional proximity makes it a natural alternative for Mississippi residents.
• University of North Texas (MS in Information Science): UNT's ALA-accredited program is one of the largest online library science programs in the country, with flexible scheduling and a range of specializations.
• San Jose State University (MLIS): SJSU's program is among the most established online MLIS options nationally, drawing students from every state. Its tuition rates for out-of-state students tend to be higher than regional alternatives, but the program offers considerable flexibility in elective focus areas.

Tuition at these institutions varies by residency status and can change from year to year, so prospective students should verify current rates directly with each school before making a decision. Students focused on budget may also want to explore cheapest library science degree online options across the country.

A Critical Warning for Future School Librarians

If your goal is to earn Mississippi's 440 Library Media license, not every ALA-accredited MLIS program will automatically qualify you. The MDE requires that your degree come from an MDE-approved program. USM's School Library track carries that approval, but out-of-state programs may or may not be recognized. Before enrolling in any program outside Mississippi, contact the MDE's Office of Educator Licensure to confirm that the specific program and coursework you plan to complete will satisfy the 440 license requirements. Enrolling in a program that turns out to be unapproved could mean additional coursework, delays, or the need to apply through an alternative pathway.

For those interested in a school librarian degree online, USM remains the safest bet for Mississippi licensure. For those pursuing public or academic librarian roles rather than a school library position, the MDE approval issue does not apply. In those cases, any ALA-accredited MLIS will generally meet employer expectations across Mississippi.

Mississippi Librarian Salary and Job Outlook in 2026

Understanding what librarians earn in Mississippi helps you set realistic expectations and compare career paths. Salaries vary significantly depending on whether you work in a school, a public library system, or a university setting, and Mississippi's cost of living creates a unique context for these figures.

How Mississippi Librarian Pay Compares Nationally

According to Bureau of Labor Statistics data, the national median annual wage for librarians and media collections specialists was $64,320 as of 2024.¹ Mississippi librarians typically earn below that national median, which is consistent with the state's lower overall cost of living. For a broader look at how pay differs across all 50 states, see our librarian salary by state breakdown. The national wage distribution provides useful benchmarks for context:

• 10th percentile: $38,690 per year²
• 25th percentile: $50,930 per year²
• 75th percentile: $80,980 per year²
• 90th percentile: $101,970 per year²

Mississippi's median librarian salary tends to fall in the lower portion of this national range. Neighboring states offer a useful comparison point. How to become a librarian in Alabama, Arkansas, and how to become a librarian in louisiana guides show that these states generally report median librarian wages in a similar band to Mississippi, while Tennessee's median often trends slightly higher, particularly in the Nashville and Memphis metro areas. If you are weighing a move or considering an online program that could position you in multiple states, these regional differences are worth noting.

School Librarian Salaries and the MDE Teacher Pay Schedule

School librarians in Mississippi are compensated according to the Mississippi Department of Education teacher salary schedule, meaning your pay is determined by two factors: your license classification tier (Class A, AA, AAA, or AAAA) and your years of experience. A Class A license (master's degree) places you on a lower pay tier than a Class AA (specialist's degree) or Class AAA/AAAA holder. Entry-level school librarians with a Class A license and zero years of experience start at the base of the schedule, with incremental raises for each year of service. Moving up a classification tier by earning a higher degree can produce a meaningful salary bump at any experience level. Because of this structure, two school librarians in the same district could earn quite different salaries depending on their credentials and tenure.

Public and Academic Librarian Salary Considerations

Public librarian salaries in Mississippi vary by the size and funding of the library system. Larger systems in cities like Jackson, Gulfport, and Hattiesburg generally offer higher starting pay than small rural branches, though even the larger systems may pay below the national median. Benefits packages, retirement through the Public Employees' Retirement System of Mississippi, and job stability can offset some of the wage gap.

Academic librarians, especially those employed at research universities, typically earn more than their public library counterparts. Positions at institutions with larger endowments or federal research funding tend to offer the most competitive compensation, along with faculty or faculty-equivalent status that may include additional benefits such as sabbatical eligibility.

Job Outlook for Mississippi Librarians

The Bureau of Labor Statistics projects national employment growth for librarians and media collections specialists at roughly 1 to 2 percent over the 2024 to 2034 period.¹ That translates to modest but steady demand. In Mississippi, most openings are driven by retirements and turnover rather than large-scale growth. School districts across the state regularly post openings for library media specialists, and public library systems in underserved areas can have difficulty filling positions, which may work in your favor if you are flexible about location.

Total national employment for this occupation stood at approximately 133,760 as of 2023.² Mississippi accounts for a small share of that total, but the state's network of public libraries, K through 12 schools, and university systems means opportunities do exist across all three career tracks. Candidates who hold an ALA-accredited master's degree and, for school roles, a valid 440 Library Media license are positioned most competitively for available openings.

Mississippi Librarian Salary at a Glance

Mississippi librarian salaries span a wide range depending on experience, setting, and location. The state's median falls below the national median of roughly $65,800, reflecting Mississippi's lower cost of living. Here is how wages are distributed across the profession statewide.

Career Pathways by Starting Point: Timelines and Costs

Your path to becoming a librarian in Mississippi depends heavily on where you are right now. The table below maps four common starting points to realistic timelines and cost ranges, so you can quickly identify your situation and plan accordingly. Costs shown are approximate and will vary by institution, residency status, and whether you attend in state or online.

Certification Renewal and Continuing Education for the 440 License

Earning your Mississippi 440 Library/Media license is a significant milestone, but keeping it active requires ongoing attention. The Mississippi Department of Education (MDE) operates on a standard five-year renewal cycle for educator licenses, and the library media endorsement is no exception. If you let your renewal lapse, you lose the authority to serve in a school library role until the endorsement is reinstated, a process that can delay your career and disrupt the school you serve.

The Five-Year Renewal Cycle

Once issued, your 440 endorsement is valid for five years. Before that window closes, you must submit a renewal application through the MDE along with documentation of continuing education units (CEUs) completed during the cycle. The MDE sets specific CEU hour requirements for each renewal period, so it is essential to verify the current threshold early in your cycle rather than scrambling at the end. Tracking your deadlines in a personal calendar or spreadsheet can prevent a costly oversight. Neighboring states follow similar renewal structures; for instance, kansas librarian license renewal procedures also run on a multi-year cycle with required professional development.

What Counts as Approved Continuing Education

Mississippi accepts a range of professional development activities toward renewal. Approved options include:

• Graduate coursework: Additional credit hours from an accredited university, whether in library science or a related field.
• MDE-approved professional development: Workshops, webinars, and training sessions that carry MDE approval codes.
• Mississippi Library Association (MLA) events: Annual conferences, regional workshops, and special programming offered through MLA frequently qualify.
• National conferences: Attendance at events hosted by organizations such as the American Library Association (ALA) or the American Association of School Librarians (AASL) can count, provided you retain certificates of attendance.

Not every conference session or online course automatically qualifies. Always confirm that an activity meets MDE standards before counting it toward your total.

Advancing Your License Class at Renewal Time

Renewal periods present a strategic opportunity. Mississippi assigns license classes (A, AA, AAA, AAAA) based on graduate credit hours completed beyond your initial degree. If you have earned additional graduate hours during your five-year cycle, you can apply for advancement to a higher class at the same time you renew. Moving up a class directly translates to a higher placement on the state salary schedule, so the coursework serves double duty: it satisfies CEU requirements and unlocks a pay increase. Other states use comparable tiered systems; indiana librarian certification levels lc1 lc7 offer a similar progression based on additional credentials.

For example, a librarian holding a Class A license who completes enough graduate hours to reach Class AA can submit both the renewal paperwork and the class advancement request together. This keeps the process efficient and ensures the salary boost takes effect as early as possible.

Staying on Track

The simplest way to protect your career is to treat renewal as an ongoing process rather than a last-minute task. Spread your continuing education across the five-year cycle, keep organized records of every certificate and transcript, and set reminders well before your expiration date. A lapsed endorsement does not just create paperwork headaches; it can remove you from the library position entirely until reinstatement is complete.

Financial Aid, Scholarships, and Loan Forgiveness for Mississippi Library Science Students

Funding a graduate degree in library science is a real concern, but Mississippi residents have access to several state, national, and employer-based programs that can significantly reduce the financial burden. Here is a practical overview of the options worth exploring in 2026.

State-Level Financial Aid and Scholarships

The University of Southern Mississippi is the only ALA-accredited library science program in the state, and Mississippi residents benefit from in-state tuition rates that are notably lower than out-of-state or private-university alternatives. USM's School of Library and Information Science has historically offered a limited number of graduate assistantship positions that provide tuition support and a stipend in exchange for work within the school or university library system. Availability varies by semester, so contacting the program directly is the best way to confirm current openings.

The Mississippi Library Association awards the Peggy May Scholarship to support students pursuing library science education.¹ This is one of the most well-known state-level awards for aspiring librarians in Mississippi, and applicants should check the MLA website for deadlines and eligibility criteria each cycle.

National Scholarships for Library Science Students

Several nationally competitive awards are open to Mississippi residents enrolled in or admitted to ALA-accredited MLIS programs. For a broader look at funding options, see our guide to library science scholarships.

• ALA Spectrum Scholarship: Supports students from underrepresented racial and ethnic groups pursuing graduate degrees in library and information science.
• ALA Century Scholarship: Designed for students with disabilities who are enrolled in ALA-accredited programs.
• Beta Phi Mu Scholarships: The international library and information studies honor society offers awards to graduate students demonstrating academic excellence.
• IMLS Laura Bush 21st Century Librarian Program: While these grants are typically awarded to institutions rather than individuals, funded projects sometimes include student scholarships or stipends. Check whether USM or another program you are considering has an active IMLS grant.

The Public Library Association awarded 150 conference scholarships for its 2026 conference, covering registration and a $750 travel stipend.² Eligibility extends to LIS students, early-career professionals, and staff at small or rural libraries, making this a practical option for Mississippi residents looking to build professional connections without a large out-of-pocket cost.

Public Service Loan Forgiveness

Librarians who work for qualifying public service employers can pursue Public Service Loan Forgiveness (PSLF). Under this federal program, borrowers who make 120 qualifying monthly payments on a Direct Loan while employed full-time by a government agency or eligible nonprofit can have the remaining balance forgiven. Public libraries, public school districts, community colleges, and state agencies are all common Mississippi librarian employers that typically meet the PSLF definition of public service. If you plan to work in any of these settings, enrolling in an income-driven repayment plan from the start of your career can maximize the benefit.

Mississippi Teacher Loan Repayment and School Librarians

Mississippi offers a Teacher Loan Repayment Program intended to attract educators to critical-shortage subject areas. School librarians who hold the 440 Library Media license may qualify if library media is designated as a shortage area in a given year. However, critical-shortage designations change annually, and whether the 440 license is included depends on current workforce data from the Mississippi Department of Education. Prospective school librarians should verify the latest shortage list before counting on this benefit, as eligibility is not guaranteed from year to year.

Practical Tips for Maximizing Aid

• Apply early for assistantships and state scholarships; funding is limited and competitive.
• Complete the FAFSA each year to remain eligible for federal loans and any institutional aid.
• If you plan to work in a public library or school, factor PSLF into your repayment strategy from day one.
• Look beyond tuition-only awards. Conference scholarships, professional development grants, and employer tuition reimbursement programs can reduce overall costs over the course of your career.

Frequently Asked Questions About Becoming a Librarian in Mississippi

Below are answers to the most common questions prospective librarians in Mississippi ask when planning their education and career path. Each response reflects 2026 requirements, salary data, and licensing standards.

What degree do you need to become a librarian in Mississippi?

The standard credential for professional librarian positions in Mississippi is a Master of Library and Information Science (MLIS) from an ALA-accredited program. Public and academic libraries typically require this degree for librarian-level roles. School librarians also need an MLIS or equivalent master's degree, combined with a valid Mississippi educator license. Some library paraprofessional or assistant positions may accept a bachelor's degree, but advancement usually requires the master's.

How do you become a certified school librarian in Mississippi?

To work as a school librarian in Mississippi, you must hold a valid Mississippi educator license with the Library/Media 440 endorsement. This requires completing a state-approved library media program at the graduate level, passing the required Praxis exam, and holding (or obtaining) a standard teaching license. Candidates who already have a teaching license can add the 440 endorsement by finishing the required library media coursework and passing the corresponding assessment.

Do you need a master's degree to be a public librarian in Mississippi?

Mississippi does not have a statewide statute mandating a master's degree for every public library employee. However, most professional librarian positions in public library systems list an ALA-accredited MLIS as a minimum qualification. Smaller or rural libraries may occasionally hire candidates with a bachelor's degree for certain roles, but a master's degree significantly improves your competitiveness and is generally expected for director or department head positions.

What is the Library/Media 440 license in Mississippi?

The 440 Library Media endorsement is the credential issued by the Mississippi Department of Education that authorizes you to serve as a school librarian (library media specialist) in a K through 12 public school. Earning it requires a graduate-level library media program, a valid Mississippi educator license, and a passing score on the appropriate Praxis subject assessment. The license must be renewed on a regular cycle through continuing education or professional development.

How much do librarians make in Mississippi?

According to the most recent Bureau of Labor Statistics data, the mean annual wage for librarians in Mississippi is approximately $49,020, while the median sits near $47,840. Salaries vary by setting and experience. School librarians follow district salary schedules that factor in education level and years of service. Academic librarians at universities may earn higher salaries, and metropolitan areas like Jackson tend to offer wages above the state average.

How long does it take to become a librarian in Mississippi?

Timeline depends on your starting point. If you already hold a bachelor's degree, an MLIS program typically takes one and a half to two years of full-time study. Some accelerated online programs can be completed in as few as 12 months. If you are pursuing a school librarian path and need both a teaching license and the 440 endorsement, expect two to three years total. Career changers without a bachelor's degree should plan for five to six years.

Can I get an MLIS online and still work in Mississippi?

Yes. Mississippi accepts an MLIS from any ALA-accredited program, whether completed online or on campus. The University of Southern Mississippi offers its own ALA-accredited program with online options, but you can also enroll in well-known online MLIS programs from institutions in other states. For school librarian certification, confirm that your chosen program's coursework aligns with Mississippi's 440 endorsement requirements before enrolling.
