Step-by-step paths to public and school librarian certification, education requirements, and career outlook in the Hoosier State
Indiana is one of the few states that does not require a master's degree for every professional library position. Instead, the Indiana State Library administers a seven-tier certification system, LC1 through LC7, that lets you enter the field with credentials as modest as an associate's degree and climb toward senior roles over time.
That flexibility creates a genuine trade-off. Starting at a lower certification level means a lower salary ceiling and a narrower range of eligible positions, while earning an ALA-accredited MLIS unlocks the upper tiers more quickly. School librarians face an entirely separate credentialing track tied to Indiana's teaching license system and a specific school librarian certification process. Understanding which path fits your situation, and what each credential actually qualifies you to do, matters more here than in most states.
Before you map out your education path, it helps to understand the three main career tracks for librarians in Indiana. Each track has its own credentialing requirements, and the differences are significant enough that choosing the wrong preparation route can cost you time and money.
Public librarians in Indiana work in tax-supported public libraries and must hold an Indiana Library Certificate issued by the Indiana State Library. This is a state-specific credential with multiple levels (LC1 through LC7), and the level you qualify for depends on your education and experience. Whether you work at a circulation desk, manage a branch, or serve as a library director, you need some form of this certificate to hold a professional position in an Indiana public library. The certification system is explored in detail in the next section of this guide.
School librarians in Indiana follow a completely separate credentialing path that runs through the Indiana Department of Education rather than the Indiana State Library. To work as a school library media specialist, you need an Indiana teaching license paired with a content-area endorsement in school library media. This typically requires coursework in both education and library science, along with student teaching or a practicum. Because the requirements differ so substantially from public library certification, the school librarian path is covered in its own dedicated section later in this article. For a broader look at how states handle this credential, see our guide to school librarian certification.
Academic librarians (those working in college and university libraries) and special librarians (employed in law firms, hospitals, corporations, or government agencies) are not required to hold any state-issued certificate in Indiana. Instead, hiring is driven by the employer. Most academic positions require a master's degree in library science, often from an ALA-accredited program, but credentialing stops there. There is no state board to satisfy and no certificate to renew. Special librarians may also need subject-matter expertise or a second graduate degree depending on the setting. If you are still weighing your options, our overview of how to become a librarian covers the general mlis degree requirements that apply across most states.
Not every library career requires certification or a graduate degree. Library assistants, clerks, and paraprofessional staff handle tasks like shelving, processing materials, and assisting patrons at the desk. These positions are a practical entry point if you want to start working in an Indiana library quickly while you decide whether to pursue formal certification or an MLIS. Many library professionals begin here, gaining firsthand experience that later informs their decision about which career track to follow.
Understanding which track aligns with your goals is the single most important first step. The credentialing requirements, degree expectations, and day-to-day responsibilities vary enough that each path deserves careful consideration before you commit to a program.
Indiana uses a seven-tier certification system, administered by the Indiana State Library, that matches education and experience to progressively more responsible library roles.1 The levels run from LC7 (the entry point) up to LC1 (the most advanced credential). Understanding where each level falls on this ladder helps you plan exactly how much education you need for the position you want.
LC7 is the most accessible credential in the system. It requires only a high school diploma or GED, plus three years of library experience. LC7 holders may serve as the new director of a public library serving a population of 3,000 or fewer, making it a realistic starting point for small-community library leadership.
LC4 calls for a bachelor's degree from an accredited college or university along with 15 college credit hours in library science. No professional experience is required. This level opens the door to director or professional staff positions at mid-size libraries, as well as supervisory roles in smaller systems.
These three levels all require a master's degree in library science from an ALA-accredited program. What separates them is experience.
LC4 is the most commonly held credential among library directors at smaller systems, because it balances a bachelor's degree with targeted library science coursework and does not require a full master's program. For librarians who want to be competitive at mid-size or large libraries, or who aspire to assistant director and department head roles, earning an online master's in public librarianship and advancing to LC3 or LC2 is the standard path. Detailed requirements for each level are outlined in the ISL Certification Manual.1
Because Indiana ties specific position eligibility to certification level, choosing the right tier early in your career planning can save both time and tuition dollars. If you are weighing whether to pursue a master's degree or start with a bachelor's-level credential, reviewing the job postings at libraries you would like to work for will give you a clear picture of which level they require. Exploring broader careers in library science can also help you decide how far to take your credentials.
No. Indiana is one of a handful of states where you can work as a certified public librarian without earning a master's degree. The state's tiered certification system allows individuals with an associate's or bachelor's degree to hold professional library positions at the LC1 through LC3 levels, covering roles that range from library aide to department head. That flexibility makes Indiana an appealing state for people who want to enter the library profession sooner or who are not yet ready to commit to a graduate program.
That said, the answer changes depending on which type of librarian career you are pursuing and how far you want to advance.
Indiana's certification ladder opens the door at the lower levels, but an ALA-accredited Master of Library and Information Science (MLIS) becomes a requirement starting at the LC4 level. Positions at LC4 and above typically include professional librarian roles, branch managers, and library directors. In practice, most metro library systems in Indiana (including Indianapolis, Fort Wayne, and Evansville) list an MLIS as a minimum qualification for professional-track openings. Even when a posting does not strictly require the degree, candidates who hold one tend to earn higher starting salaries and move into leadership roles more quickly.
If your long-term goal is a director-level position or a specialized role such as cataloging, digital services, or collection development, plan on completing an MLIS at some point in your career.
The path for school librarians in Indiana is more prescriptive. To serve as a school library media specialist in a K-12 setting, you need both a valid Indiana teaching license and graduate-level coursework in library science. This typically means completing either a full master's degree or a graduate certificate program in school librarianship from an accredited institution, such as an online MLIS school librarianship program. There is no entry-level school librarian credential that allows you to skip graduate education, so aspiring school librarians should factor this requirement into their planning from the start.
While Indiana's system is unusually open at the entry level, the competitive landscape still favors MLIS holders. Consider these practical factors:
Indiana's certification structure gives you a genuine on-ramp into library work without a master's degree, and many people build rewarding library science careers without MLIS that way. But if advancement, higher pay, or geographic flexibility matter to you, an MLIS remains the clearest path forward.
Working as a school librarian in Indiana requires a dual credential: you must hold both a valid Indiana teaching license and a School Librarian/Media Specialist endorsement. This combination ensures that school librarians are qualified educators who also have specialized training in library and media services. Below is a breakdown of the key requirements and the most practical pathway for earning the endorsement.
Indiana treats school librarians as licensed educators first. Before you can apply for the library endorsement, you need an active Indiana teaching license in any content area. Once that license is in place, you add the School Librarian/Media Specialist endorsement, which carries endorsement code 174 and covers grades K through 12.1 The endorsement signals to hiring districts that you have completed approved coursework in collection development, information literacy, instructional design, and related areas. For a broader look at how school librarian qualifications vary across the country, our national overview is a helpful starting point.
To earn endorsement code 174, you must pass the Indiana CORE Assessments exam in Library/Media Specialist.2 As of the 2025 to 2026 testing cycle, the required passing score is 220.2 You can register for the exam through the Indiana CORE testing portal, where you will also find practice materials and scheduling options. Plan to allow several weeks between registration and your test date, especially during peak licensing seasons in spring and summer.
The primary in-state preparation pathway is Indiana University's online Graduate Certificate in School Librarianship. The program requires 16 credit hours and is designed to prepare candidates for the library content exam as well as similar licensure tests in other states.3 Applicants need a bachelor's degree and a minimum GPA of 3.0.3 Because the certificate is delivered fully online, it is accessible to working teachers across Indiana and beyond.
This is not a full master's degree program, which makes it especially appealing for career changers who already hold a teaching license and want to move into a school library role without the time and cost of a second graduate degree. If you do eventually want a full master's, consider exploring online school librarian master's programs accredited by ALA. Completing the certificate coursework, passing the CORE Library/Media Specialist exam, and holding a valid teaching license are the three pillars you need to secure the endorsement.
If you are a classroom teacher looking to transition into the school library, the path is more straightforward than you might expect. You do not need to start from scratch with a new master's degree. Adding the endorsement through a graduate certificate program like Indiana University's lets you build on your existing teaching credential. The 16-credit curriculum is focused and practical, covering the competencies the state requires without duplicating general education coursework you have already completed. Once you pass the CORE exam at the 220 threshold, you can apply for the endorsement through the Indiana Department of Education's online licensing system.
Indiana's public librarian certification is administered by the Indiana State Library's Professional Development Office. The process begins with a paper application and ends with a five-year certificate. Here is the typical sequence from start to finish.
Indiana does not maintain formal reciprocity agreements with other states for librarian certification.1 If you hold credentials from Illinois, Ohio, Michigan, or any other state, you cannot simply transfer them for an equivalent Indiana certificate. Instead, the Indiana State Library evaluates each out-of-state applicant individually and places them into the appropriate level of the LC certification system based on their education, professional experience, and the type of position they will hold.
The good news for MLIS holders is that Indiana accepts degrees from ALA-accredited programs regardless of where they were earned.1 The Indiana State Library verifies accreditation status through the ALA Office for Accreditation. An ALA-accredited master's degree satisfies the education requirement for higher certification levels, so the key variable in your placement is how your professional experience translates within Indiana's framework. If you are still exploring ala-accredited mlis online programs, earning your degree from any accredited institution will satisfy Indiana's education requirement.
Certification level placement depends on three factors: your degree, the position you are filling, and the population served by the library.1 An out-of-state certificate can serve as supporting documentation during this review, but it does not automatically dictate your Indiana level.
If your degree comes from a program that is not ALA-accredited, expect the Indiana State Library to conduct a more detailed individual evaluation of your coursework and credentials before determining your placement.
There is no separate application form for out-of-state candidates. You use the same Librarian Certification Application as in-state applicants, submitted by email, upload, or mail.1 You will need to provide:
Continuing education credits earned in other states are accepted by Indiana, which can be helpful when it comes time to renew your certification on its five-year cycle.1
Before formally applying, reach out to the Indiana State Library's Professional Development Office for a credential evaluation. Staff can review your transcripts and experience and give you a realistic sense of where you will land on the LC scale. This step is especially important because neighboring states use very different certification structures. A senior-level credential in Ohio or Michigan may not map neatly onto a specific Indiana level, and finding that out after you have already accepted a position can create complications.
Taking this proactive step saves time and helps you negotiate with potential employers, since your certification level can affect both your eligibility for certain positions and salary expectations.
Choosing the right library science program is one of the most consequential decisions you will make on your path to certification. Indiana residents have a strong in-state flagship option, several relevant certificate pathways, and a wide selection of online MLIS programs from accredited institutions across the country. The Indiana State Library (ISL) accepts any degree from an ALA-accredited program for the higher certification levels (LC4 and above), so you are not limited to schools within state borders.
Indiana University Bloomington's Master of Library Science (MLS) program, housed in the Luddy School of Informatics, Computing, and Engineering, is the only ALA-accredited library science master's program based in Indiana. The program is available both on campus and fully online, making it accessible to working professionals across the state. As of the 2025, 2026 academic year, in-state graduate tuition runs roughly $500 to $550 per credit hour, putting the total cost of the 36-credit MLS in the range of $18,000 to $20,000 before fees and materials. IU Bloomington also offers dual-degree options and specialization tracks in areas such as archives, data science, and children's and youth services.
Indiana University Indianapolis (formerly IUPUI) does not offer a standalone ALA-accredited MLIS, but it plays a role in preparing school library professionals. Students pursuing a school librarian media specialist license in Indiana can combine coursework through IU's system with education licensure requirements. Some candidates complete a graduate certificate in school librarianship alongside or after earning a master's degree. If your goal is to work in a K-12 setting, check with IU Indianapolis's School of Education for the latest program options and practicum requirements, which must align with Indiana Department of Education licensing standards.
Because the ISL recognizes any ALA-accredited master's degree, many Indiana residents enroll in online MLIS programs offered by institutions outside the state. Some of the most commonly chosen options include:
Total program costs vary widely depending on residency status, institution, and pace of study. Expect to pay anywhere from roughly $15,000 for an affordable library science degree online up to $50,000 or more at some private or out-of-state universities. When comparing options, keep these factors in mind:
Taking the time to compare tuition, format, specialization tracks, and student support services across several ala accredited online mlis programs will help you find the best fit for your career goals and budget.
Librarians in Indiana earn a median annual wage that trails the national median by several thousand dollars, but compensation varies significantly by experience, certification level, and location. The table below compares Indiana's statewide figures with the national median and highlights top-paying metro areas within the state. Nationally, the Bureau of Labor Statistics projects approximately 3% job growth for librarians and media collections specialists from 2022 to 2032, roughly in line with the average for all occupations. Indiana's public library system is one of the most extensive per capita in the country, which helps sustain steady demand for certified librarians across the state.
| Area | Median Salary | 10th Percentile | 90th Percentile | Employment |
|---|---|---|---|---|
| United States (National) | $65,800 | $38,740 | $103,510 | 143,440 |
| Indiana (Statewide) | $56,280 | $34,050 | $86,230 | 2,960 |
| Indianapolis, Carmel, Anderson Metro | $60,410 | $36,720 | $90,150 | 1,110 |
| Fort Wayne Metro | $55,030 | $33,490 | $83,760 | 230 |
| South Bend, Mishawaka Metro | $53,640 | $32,280 | $81,500 | 130 |
Indiana library certificates do not last forever. Every certificate issued by the Indiana State Library (ISL) is valid for five years, and holders must complete continuing education during that window to qualify for renewal. Understanding the renewal requirements early helps you avoid a lapse that could interrupt your career.
Indiana measures continuing education in Library Education Units, commonly called LEUs. One LEU equals one contact hour of approved continuing education. The number of LEUs you need per five-year renewal cycle depends on your certification level:
Not every educational activity automatically qualifies. To count toward renewal, the content must be relevant to library operations, management, information science, or a related professional competency. College coursework can also be converted into LEUs, with one semester credit hour typically equating to 15 LEUs.
If you hold an LC6 or LC7 certificate and serve in a director-level position, a portion of your LEUs must specifically address library administration. These administrative LEUs cover topics such as budgeting, human resources, strategic planning, governance, and facilities management. Librarians interested in building these competencies may want to explore an online master's in library administration before stepping into a director role. This requirement exists because directors carry responsibilities that extend well beyond day-to-day library services, and the state expects them to stay current in those areas.
Indiana librarians have a wide range of options for accumulating LEUs, making it realistic to fulfill the requirement even with a busy schedule:
Many librarians blend in-person conferences with online learning to spread their LEU accumulation across the full five-year period rather than scrambling at the end.
If your certificate lapses, you are no longer eligible to work in a position that requires Indiana library certification. Public libraries that receive state funding are required to employ certified staff, so a lapsed credential is not something an employer can overlook. You will need to complete any outstanding LEU requirements and submit a renewal application to the ISL before you can return to a certified role. In some cases, additional documentation or fees may apply. Staying on top of your renewal timeline is the simplest way to protect your standing and avoid a gap in employment.
Below are answers to some of the most common questions prospective librarians ask about Indiana's certification process, education requirements, and application procedures. For detailed breakdowns of each certification level, degree options, and salary data, see the corresponding sections earlier in this guide.
