Step-by-step paths to school, public, and academic librarian careers in Illinois — including licensure, programs, costs, and salary expectations.
Illinois requires school librarians to hold a Professional Educator License with a Library Information Specialist endorsement, a credential that demands a master's degree, student-teaching hours, and passing scores on state content-area tests. Public and academic librarians face no state license but nearly always need an ALA-accredited MLIS to compete for professional positions. Special library roles add yet another layer, often favoring subject expertise alongside the degree.
The practical challenge is that these paths differ sharply in cost, timeline, and regulatory complexity. An MLIS alone can take two years and run from roughly $20,000 to over $60,000 in tuition, and the PEL endorsement adds its own fees, fieldwork, and processing time on top of that. With median librarian salaries in Illinois hovering near $60,000, choosing the right credential track and program format has direct financial consequences. This guide walks you through every step, from how to become a librarian in the state to program comparisons, salary data, and financial aid options.
Not all librarian roles in Illinois follow the same credentialing path. School librarians face the most structured requirements because they work within the state's educator licensing system, while public and academic librarians are governed primarily by employer expectations and professional standards. The table below breaks down what each track demands so you can identify the path that fits your goals.
| Requirement | School Librarian (Public K‑12) | Public Librarian | Academic Librarian |
|---|---|---|---|
| Minimum Degree | Master's degree (typically an MLIS or equivalent) | MLIS from an ALA accredited program is the standard expectation | MLIS from an ALA accredited program; a second master's or doctoral degree is often preferred |
| State License or Credential | Professional Educator License (PEL) with a Library Information Specialist endorsement, issued by ISBE | No state license required; hiring standards are set by individual library systems and guided by Illinois Public Library Standards | No state credential; hiring is handled entirely by the college or university |
| Content Area Testing | Must pass the applicable Illinois Licensure Testing System content area test for library information specialist | None required by the state | None required by the state |
| Typical Employer Requirements | Must hold a valid PEL endorsement before starting the role in a public school district | Most library directors and boards expect an ALA accredited MLIS; some smaller systems accept a bachelor's degree plus relevant experience for entry level positions | Institutions set their own criteria, which frequently include subject expertise, research experience, or faculty status eligibility |
| Continuing Education | PEL renewal requires ongoing professional development hours on a five year cycle through ISBE | Encouraged through the Illinois State Library's continuing education programs; some library systems mandate annual training hours | Varies by institution; many academic librarians pursue scholarship and professional development for tenure or promotion |
| Private vs. Public Distinction | Private K‑12 schools in Illinois are not required to hire PEL endorsed librarians, though many prefer candidates with an MLIS | Not applicable; public libraries operate under a single framework regardless of funding source | Not applicable; both public and private colleges and universities follow their own institutional hiring policies |
| Key Professional Standards | Illinois State Board of Education (ISBE) educator licensing rules and Illinois School Code | Illinois Public Library Standards, maintained by the Illinois State Library, guide service benchmarks and staffing expectations | Association of College and Research Libraries (ACRL) standards and individual institutional policies |
Working as a school librarian in Illinois requires a Professional Educator License (PEL) with a Library Information Specialist endorsement. The Illinois State Board of Education (ISBE) oversees this licensure process, and each step has specific requirements, fees, and timelines you need to plan for. Here is the full process from start to finish.
Before you can add the Library Information Specialist endorsement, you must already hold a valid Illinois PEL.1 The endorsement is classified as a subsequent teaching endorsement, meaning it builds on an existing license rather than standing alone.2 If you do not yet have a PEL, you will need to complete an ISBE-approved educator preparation program, pass the required licensure tests for your initial teaching area, and apply through the ISBE Educator Licensure Information System (ELIS) portal. The initial PEL application fee is $150, plus a $50 registration fee.3
This is the step that trips up the most candidates. You must complete a minimum of 18 semester hours in approved library and information science coursework.4 Critically, not every MLIS program qualifies. A general MLIS from an ALA-accredited institution does not automatically make you eligible for the Illinois endorsement. The coursework must come from, or align with, an ISBE-approved educator preparation program that specifically prepares candidates for the Library Information Specialist endorsement. Programs at some Illinois universities include endorsement-specific tracks within their library science degrees, but you should confirm ISBE approval before enrolling. If you are considering online mlis school librarianship options, verify that the program meets Illinois-specific requirements. If you earn a general MLIS without completing an approved preparation program, you may need additional coursework to qualify.
Illinois requires candidates to pass a content-area test through the Illinois Licensure Testing System. The current test for Library Information Specialist is test 220, and you need a minimum passing score of 240.1 Test fees range from $122 to $150.3 After sitting for the exam, expect your scores to post within two to four weeks.3 Plan accordingly so that test results are available before you submit your endorsement application.
Once your approved coursework is complete and your test scores have posted, you can apply for the Library Information Specialist endorsement through the ELIS portal. The endorsement application fee is $50.5 You will need to ensure your official transcripts are on file with ISBE; transcript processing can take one to four weeks.5 The endorsement application itself typically takes two to six weeks to process.2 ISBE recommends beginning the application process eight to ten weeks before you need the endorsement to be active, especially if you are trying to meet a school district hiring timeline.5
Note that the endorsement application does not require a separate fingerprinting or background check, since those were completed as part of your initial PEL.1
Your PEL is valid for five years.1 To renew, you must complete 120 professional development hours during each five-year cycle. The renewal window opens on April 1, and licenses that are not renewed lapse on August 31. Staying current with your professional development is essential, as a lapsed license means you cannot legally serve as a school librarian in Illinois until it is reinstated. For a broader look at how other states handle school librarian certification, our national overview compares requirements side by side.
Planning ahead is the key to a smooth experience. Between transcript processing, test score posting, and ELIS application review, the full timeline from submitting your final coursework to holding an active endorsement can stretch to three months or more. If you are targeting a specific school year start date, work backward from that date and give yourself generous lead time.
Becoming a licensed school librarian in Illinois follows a clear sequence of academic, testing, and licensing milestones. Here is the typical timeline from holding a bachelor's degree to receiving your Professional Educator License (PEL) with a Library Information Specialist endorsement.
Illinois is home to multiple ALA-accredited master's programs in library and information science, giving prospective librarians strong in-state options. Whether you want to work in a public library, an academic setting, or a K-12 school, choosing the right program matters. For a broader look at best library science schools illinois, see our state program directory. Below is a comparison of the key Illinois-based options, along with notes on out-of-state alternatives.
The UIUC iSchool consistently ranks among the top library science programs in the nation and is one of the few programs in Illinois that can lead directly to PEL endorsement for school librarians. Its fully online option makes the program accessible to students across the state and beyond.
Chicago State University provides another ALA-accredited pathway, with flexible evening and online scheduling designed for working professionals. However, candidates who plan to pursue the PEL Library Information Specialist endorsement should verify with both the university and the Illinois State Board of Education whether additional coursework or steps are required.
Several other Illinois universities offer library-related graduate programs or endorsement pathways, even though they do not hold ALA accreditation for a standalone MLIS degree. Dominican University, for instance, has historically been recognized for its school library media emphasis. Illinois State University and Northern Illinois University also offer coursework and endorsement-track programs relevant to school librarianship. If you are pursuing public or academic library roles where ALA accreditation is a hiring expectation, confirm that your chosen program meets that standard.
Illinois residents are not limited to in-state schools. Nationally recognized ala accredited online mlis programs, such as those at San Jose State University or Syracuse University, accept students from across the country. These programs can prepare you for public, academic, or special library positions. However, if your goal is an Illinois PEL with the Library Information Specialist endorsement, completing an out-of-state program may require additional steps to satisfy ISBE requirements. You should contact ISBE directly to confirm endorsement eligibility before enrolling in a program outside Illinois.
When comparing options, keep these factors in mind:
Tuition figures noted above reflect 2025-2026 published rates and may change. Always verify current costs with the institution before making enrollment decisions.
Not everyone who enters the library profession follows the same route. Whether you are switching careers, already working in a library support role, or hold a graduate degree in another field, Illinois offers several practical pathways into librarianship.
This is one of the most common questions prospective school librarians ask, and the answer is yes. The Illinois Professional Educator License (PEL) with a Library Information Specialist endorsement does not require prior classroom teaching experience. Approved programs are designed to equip candidates with the education coursework, instructional methods training, and supervised practicum hours needed to work in a school setting. If you are entering from a non-education background, you will complete coursework in areas like curriculum design, literacy instruction, and educational technology as part of your program. The practicum component gives you hands-on experience in a school library before you apply for your endorsement. For a broader look at requirements across the country, see our guide to school librarian qualifications.
If you already work in a library as a paraprofessional, library assistant, or circulation clerk, you have a head start. Some paraprofessionals hold a library support staff certification or have completed relevant coursework. To move into a professional librarian role, the typical next step is earning an MLIS from an ALA-accredited program. Your on-the-job experience can inform your practicum placement and may help you stand out in competitive hiring, though it generally does not substitute for graduate-level coursework. If your goal is a school librarian position, you will also need to complete an approved PEL endorsement program, which can often be bundled with or built into your MLIS coursework.
Career changers who hold a master's degree in another discipline have an efficient option. Rather than completing a full second master's, several Illinois institutions offer post-master's certificate or endorsement-only programs in library and information science. These programs focus specifically on the competencies required for the Library Information Specialist endorsement. They are shorter and less expensive than a full MLIS, and they satisfy the requirements for the PEL endorsement when the program is state-approved. Check with individual institutions to confirm that their post-master's track leads to endorsement eligibility.
If your interest lies in public, academic, or special libraries rather than school settings, you do not need an Illinois PEL at all. These positions typically require an MLIS from an ALA-accredited program, but they are not governed by the Illinois State Board of Education's licensure system. This distinction is important for career changers: once you earn your MLIS, you can apply directly for public or academic librarian positions without completing additional endorsement coursework or a teaching practicum. Prospective public librarians may want to explore online master's in public librarianship programs as a flexible option. Many career changers find this a more streamlined entry point into the profession, especially if they have transferable skills in research, technology, or community engagement.
Understanding what librarians earn across Illinois can help you set realistic expectations and target the settings and regions that align with your financial goals. Salaries vary significantly depending on library type, geographic area, and experience level.
As of 2024, the statewide median annual wage for librarians and media collections specialists in Illinois is approximately $62,360.1 The mean annual wage reported in recent Bureau of Labor Statistics data is in a similar range.2 To give you a sense of the earning spectrum, entry-level positions and part-time roles in smaller communities may fall considerably below the median, while experienced librarians in senior or administrative roles, particularly in the Chicago metro area, can earn well above $80,000 per year. The spread between the lowest-paid and highest-paid librarians in the state is substantial, often spanning $30,000 or more.
Compared to the national median for librarians, which the Bureau of Labor Statistics has reported in the low-to-mid $60,000 range in recent years, Illinois tracks close to or slightly above the national figure. For a broader look at how compensation compares across the country, see our librarian salary by state breakdown.
Where you work in Illinois matters a great deal for your paycheck.
While detailed Illinois-specific salary breakdowns by employer type (school, public, academic) are not published in a single convenient source, national trends offer useful guidance. Academic librarians at four-year institutions and school librarians in well-funded suburban districts tend to earn above the state median, while public librarians in smaller communities often earn below it. In the Chicago suburbs, school librarians holding a Professional Educator License with a Library Information Specialist endorsement may benefit from teacher salary schedules that include step increases for advanced degrees and years of service. Exploring library science careers can help you compare earning potential across different roles.
The Bureau of Labor Statistics projects modest but steady growth for librarian positions nationally through the early 2030s, with an expected increase in the range of 3 to 6 percent over a ten-year period. Illinois-specific projections from the Illinois Department of Employment Security have historically tracked near the national average, though precise 2024 to 2034 figures for the state have not yet been finalized. Retirements across the profession are expected to create additional openings beyond what raw growth numbers suggest, particularly in public and school library settings.
If maximizing your earning potential is a priority, targeting positions in the greater Chicago area or at academic institutions with competitive salary scales will give you the strongest starting point. Pairing an ALA-accredited MLIS with a specialized endorsement or a second subject-area credential can also help you stand out in a field where demand remains stable but competition for the best-paying roles is real.
Illinois is home to one of the largest public library networks in the United States, yet roughly one million residents still lack direct public library service, according to Illinois Public Libraries by the Numbers for FY2024 from the Illinois Library Association. That gap highlights both the reach of the state's library infrastructure and the ongoing need for qualified librarians across Illinois communities.
Understanding the full cost picture before you enroll helps you budget realistically and take advantage of every funding opportunity. Below is a breakdown of what Illinois residents can expect to pay for an MLIS degree and, if pursuing school librarianship, the additional licensure fees.
MLIS tuition at Illinois institutions varies considerably depending on the school and format. As referenced in the program comparison earlier in this guide, total tuition for an ALA-accredited MLIS ranges from roughly $18,000 to over $50,000. Programs at public universities such as the University of Illinois Urbana-Champaign tend to fall on the lower end for in-state students, while private institutions like Dominican University carry higher sticker prices but may offset costs through institutional aid. Online programs from out-of-state schools sometimes charge a flat per-credit rate regardless of residency, so comparing total cost of attendance is essential. If budget is your primary concern, our ranking of the cheapest library science degree online programs is a useful starting point.
If you plan to work as a school librarian, you will need a Professional Educator License (PEL) with a Library Information Specialist endorsement. Budget for these additional expenses:
Public librarians in Illinois generally do not need a PEL, which means they can skip the licensure exam, application, and fingerprinting costs entirely. That saves several hundred dollars compared to the school librarian pathway.
For a typical Illinois resident completing an MLIS at a public university and obtaining a PEL with the Library Information Specialist endorsement, the all-in cost falls in the range of $20,000 to $25,000. Choosing a private institution or an out-of-state online program could push that figure to $40,000 or more. Those pursuing public or academic librarianship without a PEL can subtract roughly $300 to $350 in licensure-related fees from the total.
Several funding sources can reduce your out-of-pocket costs significantly. For a deeper look at available awards, see our guide to mlis scholarships and financial aid.
Combining two or three of these sources can cut your net cost substantially. Start researching financial aid options at the same time you research programs so you can make an informed, side-by-side comparison of what each path will actually cost you.
Joining professional organizations is one of the most practical steps you can take as a new or aspiring librarian in Illinois. These groups offer networking, job leads, continuing education, and advocacy support that can shape your entire career.
The Illinois Library Association (ILA) is the state's largest professional body for librarians of all types. Membership gives you access to an annual conference, professional development workshops, mentorship opportunities, and a job board focused on Illinois positions. ILA also advocates at the state level for library funding and policy.
The Illinois School Library Media Association (ISLMA) serves school librarians specifically. If you hold or are pursuing a PEL with a Library Information Specialist endorsement, ISLMA offers targeted workshops, curriculum resources, and a community of peers who understand the unique challenges of K-12 library programs.
Illinois is served by two regional library systems: Reaching Across Illinois Library System (RAILS) and Illinois Heartland Library System (IHLS). Both provide free or low-cost continuing education, interlibrary loan coordination, consulting services, and grants that support library staff development. Many of these training opportunities count toward PEL renewal requirements.
The American Library Association, headquartered in Chicago, is the largest library organization in the world. ALA membership provides access to national job listings through ALA JobLIST, significant discounts on the annual conference and midwinter meeting, and the chance to serve on committees. Committee involvement and conference presentations are resume builders that signal leadership and subject expertise to hiring committees. Student membership rates are available for those still completing an MLIS degree.
Two state resources deserve a spot in every Illinois librarian's bookmarks. The Illinois State Board of Education (ISBE) maintains the Educator Licensure Information System (ELIS), where you apply for, renew, and manage your Professional Educator License and endorsements. This is the portal you will use throughout your career to track renewal credits and update your credentials.
The Illinois State Library, a division of the Secretary of State's office, oversees public library certification, administers library development grants, and maintains statewide data on library services. If you are interested in public librarianship, the State Library's grant programs and per capita aid resources are essential to understand.
Consider these practical benefits when deciding where to invest your membership dollars:
Even before you finish your degree, student memberships in ILA and ALA are affordable ways to start building your professional network and staying current with trends in the field. Exploring broader masters in library science guide content can also help you weigh your options as you plan your next steps.
