Prerequisites and Application Tips for MLS Programs

Applying for MLS Programs: Where to Start

Librarians don’t just organize books—they connect communities, preserve knowledge, and power lifelong learning. It’s a career that blends purpose with impact. And it all starts with one pivotal step: choosing the right Master of Library Science (MLS) program and submitting an application that stands out.

The MLS is more than just a degree—it’s the credential that unlocks opportunities in public, academic, school, and special libraries. It’s the bridge between passion and professional recognition in the field of library and information science.

But getting into a top-tier MLS program? That’s where many fall short—not because they lack the drive or intellect, but because they’re navigating a process filled with fine print, hidden expectations, and unspoken rules.

That ends now.

This guide breaks down the exact prerequisites most MLS programs expect, and more importantly, shows how to craft an application that rises above the rest. Whether coming straight from undergrad, shifting careers, or mentoring someone through the process, the insights here deliver clarity and an edge.

And since no two MLS programs are exactly alike—some focus on archives, others on digital librarianship, youth services, or data management—finding the right fit matters just as much as meeting the basic requirements.

So let’s cut through the confusion and build a foundation that gets results.

Understanding the Prerequisites for MLS Programs

Before an application ever gets reviewed, admissions committees want one question answered:

“Is this candidate ready for graduate-level work—and committed to the profession?”

That’s where prerequisites come in. They serve as the baseline, the non-negotiables that every serious applicant must meet (or strategically work around). Here’s how to check every box—and then some.

Educational Background

Bachelor’s Degree:

No surprises here. A bachelor’s degree from an accredited institution is required across the board. The specific major? More flexible than most think.

Preferred Undergraduate Majors:

Some fields naturally align with the research, communication, and organizational skills demanded in librarianship:

• Humanities – English, History, Literature, Philosophy: Ideal for critical thinking, writing, and information literacy.

• Social Sciences – Sociology, Political Science, Anthropology: Great for understanding diverse communities and user behavior.

• Information Technology/Computer Science – Growing demand for digital skills makes this background highly valuable.

• Languages – Especially beneficial for roles in multilingual or international collections.

Still, no degree is “wrong.” What matters most is the ability to think analytically, communicate clearly, and manage information effectively.

GPA Requirements:

Many programs expect a minimum GPA of 3.0—but there’s room for nuance. Applicants with lower GPAs can still compete with strong letters, relevant experience, or standout essays. Some schools even offer conditional admission.

Standardized Tests (GRE/MAT)

Current Trends:

Here’s the good news: a growing number of MLS programs are eliminating GRE and MAT requirements altogether. Programs now prioritize academic transcripts, experience, and writing ability over test scores.

Programs That Still Require Them:

Some institutions—especially competitive or research-heavy ones—still expect GRE or MAT scores. For those, preparation is key. That means practice exams, review courses, and a study timeline that doesn’t leave anything to chance.

Bottom Line:

Check the admissions page of each program. Requirements can shift year to year—and assuming could cost a seat in the program.

Work/Volunteer Experience

While not always mandatory, relevant experience is a secret weapon in the application process. It shows initiative, understanding of the field, and a track record of skills that transfer seamlessly into graduate study.

Types of Experience That Stand Out:

• Public, academic, or special library roles

• Archives and records management

• Volunteer work in schools or community libraries

• Customer service or education roles with heavy information or tech components

No Experience Yet?

Start small. Volunteer. Shadow a librarian. Join a local library friends group. Even a few hours a week builds credibility—and insight.

Letters of Recommendation

Admissions committees don’t just want transcripts. They want voices that vouch for an applicant’s potential.

Who to Ask:

• Former professors (especially those in writing-heavy or research-driven courses)

• Supervisors from library or related jobs

• Mentors who can speak to work ethic, communication, and passion for librarianship

Statement of Purpose / Personal Essay

Think of this as the applicant’s audition on paper. It’s the chance to explain why this career matters, what the journey has looked like, and where it’s going next.

What Admissions Committees Want:

• Clear motivation for entering the field

• Specific career goals and how the program supports them

• Evidence of insight into the profession (not just “I love books”)

• A strong alignment with the program’s focus and values

Other Potential Requirements

Some programs include additional hurdles. They’re not universal—but if they apply, they matter.

• Writing Samples – Often used to assess analytical or research ability

• Interviews – Especially for competitive or cohort-based programs

• Specific Course Prerequisites – Rare, but some programs may expect basic coursework in statistics, education, or computer science

Top Application Tips for Aspiring MLS Students

Meeting the requirements opens the door.

But how an application is presented determines whether that door actually opens.

Here’s how to build an application package that commands attention and earns offers of admission.

Research Programs Thoroughly

All MLS degrees are not created equal. Some specialize in archives. Others lean into data science, youth services, or digital librarianship (see MLS degree program guide).

Find the right fit—and prove it in the application.

Look for:

• Areas of Specialization: Align with career goals. Want to work in academic reference? Youth services? Corporate information centers? Choose accordingly.

• Program Format: Online, hybrid, or on-campus—make sure it matches your learning style and schedule.

• Faculty Expertise: Who’s teaching? What are their research interests? Do they match your goals?

• Reputation & Alumni Network: Connections open doors. A strong alumni network can make the job hunt easier post-graduation.

Craft a Compelling Statement of Purpose

The statement of purpose isn’t filler. It’s a decision-maker.

This is where applicants explain who they are, why they belong in the field, and what they plan to do with the degree. Generic essays get generic results. Tailored, passionate statements stand out.

Key Elements:

• Tell your story—what brought you to librarianship?

• Highlight defining moments: experiences, mentors, challenges overcome.

• Clearly state career goals.

• Show deep understanding of current trends in the profession.

• Match your ambitions to the specific program’s strengths.

And proofread like your future depends on it—because it does.

Secure Strong Letters of Recommendation

One weak letter can tank an otherwise solid application. Strong ones, on the other hand, validate every claim made in the personal statement.

Tips for success:

• Ask early. Give recommenders at least 3–4 weeks’ notice.

• Choose those who truly know your work, not just those with impressive titles.

• Provide a résumé, personal statement draft, and program details.

• Follow up respectfully—and send a thank-you after submission.

Highlight Relevant Experience and Skills

Even if past jobs weren’t in libraries, they likely built skills that translate perfectly into library science.

Think:

• Customer Service: Handling patrons with care and professionalism

• Education or Tutoring: Instructional design, public speaking

• Research or Data Management: Organizing, verifying, and presenting information

• Technology Use: Software fluency, digital troubleshooting, metadata handling

Pay Attention to Deadlines and Requirements

Obvious? Maybe. Ignored? Too often.

Create a system that prevents last-minute errors:

• Build an application calendar with all deadlines and document requirements.

• Label and format every file exactly as requested.

• Submit early—technical glitches on the last day are no excuse.

Consider a Portfolio (If Applicable)

Some programs welcome (or even encourage) applicants to submit portfolios showcasing past work.

Strong portfolio items include:

• Research papers

• Digital projects

• Instructional materials

• Outreach or programming campaigns

• Library displays or community initiatives

Only include pieces that demonstrate readiness for graduate-level work and align with program values.

Prepare for Interviews (If Required)

A few programs, especially competitive or cohort-based ones, may include an interview stage.

Be ready:

• Research common MLS interview questions.

• Practice concise, confident answers.

• Dress professionally—even on Zoom.

• Ask thoughtful questions that reflect genuine interest in the program.

Addressing Common Concerns and FAQs

Doubts creep in. Questions multiply. And unfortunately, too many promising candidates talk themselves out of applying before they even start.

Let’s clear the fog and tackle the most common concerns head-on—with direct answers that move things forward.

“My undergraduate degree isn’t related to library science—can I still apply?”

Absolutely.

MLS programs do not require a specific undergraduate major.

What matters is the ability to think critically, write clearly, and engage with information. Whether the background is in biology, art history, or business, it can be framed as an asset—especially when paired with a clear passion for the field.

Focus on transferable skills: communication, research, organization, collaboration. Then, back it up with relevant experience or a strong statement of purpose.

“Is the GRE really that important?”

Not anymore.

A growing number of MLS programs have dropped the GRE requirement entirely, recognizing that standardized test scores often fail to predict success in library school—or the profession.

For programs that still require it, treat the GRE as a formality to be managed, not a deal-breaker.

The real differentiators? GPA, experience, recommendations, and a well-written statement of purpose.

“How can I gain library experience if I don’t have any?”

It’s more accessible than it seems.

Start by contacting local public libraries, academic libraries, or special collections. Many welcome volunteers—especially for events, shelving, or digital projects.

Other great options:

• Internships or practicums (some colleges offer credit)

• Part-time jobs in circulation, reference, or youth services

• Community service that involves teaching, organizing, or outreach

Even virtual library internships or remote metadata projects can count. The key is to show initiative and interest.

“What makes a strong statement of purpose stand out?”

Three words: Clarity, authenticity, alignment.

• Clarity: Stay focused. Admissions committees read dozens—sometimes hundreds—of essays. Make the message obvious: why this field, why this program, why now.

• Authenticity: This isn’t a résumé in paragraph form. It’s a story. Show real passion. Use specific examples.

• Alignment: Demonstrate that the program’s values, curriculum, or faculty align with your goals. That connection creates instant credibility.

Generic essays blend in. Specific, intentional essays rise to the top.

“How many programs should I apply to?”

There’s no magic number, but a strategic range of 3 to 5 programs is a smart target.

Apply to:

• At least one safety program (with higher acceptance rates)

• One or two target programs (where your profile closely matches the average admitted student)

• One reach program (more competitive, but worth aiming for)

Balance ambition with realism—and factor in application fees, deadlines, and workload.

Let’s Wrap it Up

The path to becoming a librarian starts long before the first MLS class begins. It starts now—with smart decisions, strategic preparation, and the kind of application that demands attention.

Yes, the process takes effort. But so does anything worth doing. And few careers offer what librarianship does: meaningful work, community impact, intellectual challenge, and the chance to lead in a world drowning in disorganized information.

By understanding the prerequisites, choosing the right programs, and presenting a polished, passionate application, the odds shift dramatically in your favor. Not just for getting into library school—but for building a career that lasts.

So here’s the next move:

• Map out potential programs.

• Gather documents.

• Reach out for experience.

• Write with purpose.

• Submit with confidence.

For those serious about shaping the future of information, this is the moment to step forward.

Explore additional resources. Contact admissions teams. Talk to professionals already in the field.

But above all—take action.

The future of librarianship needs sharp minds, steady hands, and passionate leaders.

There’s no reason that future can’t start with this application.
