How to Choose a Master's in Library Science Program

When comparing potential library science programs, prospective students should consider factors such as cost, location, and length of time to degree. The cost of a library science master's degree varies widely, with in-state public institutions often charging the lowest tuition. Some programs may offer financial support to students. Location may narrow options to local schools, particularly for students who are unable to relocate for their degree. These students may benefit from the flexibility of an online degree, which allows students to enroll at the top online library science programs without relocating or leaving their current job.

While most library science programs require two years to earn a master's degree, the length of time can vary depending on internship requirements, specialized courses, or final project requirements. Some programs also offer part-time options, which add time to the degree but may work well for students balancing school with work or family obligations.

In addition to cost, location, and time to degree, prospective students should also consider the specializations each program offers. Checking the program's curriculum and how often the program offers required classes can also help students narrow their choices, as can looking at a program's placement record in different specializations. Students should check a program's accreditation status, which can affect their job prospects after graduation.

Programmatic Accreditation for Master's in Library Science Programs

Accreditation ensures that colleges, universities, and academic programs follow the best practices in their field and use the highest standards for educating students. In addition to regional and national accreditation, which evaluate an entire college or university, programmatic accreditation reviews one specific program, such as a business school, teaching program, or social work program. For library science, the American Library Association (ALA) accredits master's programs. As a professional organization dedicated to advancing library science, the ALA applies the highest standards when reviewing programs.

When evaluating programs, prospective students should check the accreditation status. Many certifications and licenses only accept master's degrees from accredited programs, with some states only granting public library or school library licenses to candidates with an ALA-accredited degree. In addition, an unaccredited degree may hurt graduates in the job market because many employers only hire candidates with an ALA-accredited degree. Prospective students can use the ALA list of accredited programs to determine which programs they should apply to.

Master's in Library Science Program Admissions

Library science programs evaluate potential graduate students to ensure they meet prerequisites and to determine which applicants should gain admission to the program.

Because of that, library science applicants should plan to spend several weeks or more compiling their applications.

Each program sets its own admissions requirements, so when researching prospective programs, applicants should create a timeline with deadlines and required admission materials. While candidates may be able to reuse some materials, programs may ask for specialized essays or customized materials. The admissions process for an online program may also require more steps than on-campus program admission. Prospective students may apply to multiple programs to increase their chances of receiving an admissions offer and financial support.
