How do you become a medical science liaison? Build deep scientific or clinical expertise, usually through a doctorate such as a PhD, PharmD, or MD, then add the skills the field role needs: interpreting clinical data, presenting science clearly, building peer relationships with experts, and working within compliance rules. This free self-assessment shows where to focus next.

Last updated: October 17, 2026 · Written by QKC Health · Based on published MSL professional guidance and official certification and regulatory sources

**What this assessment is:** a self-assessment of your development needs across core medical science liaison (MSL) competency areas, with a 30/60/90-day roadmap. It draws on published guidance from MSL and medical affairs professional bodies and on the certification and regulatory sources listed at the end of this page.

**What it is not:** a validated hiring tool, a certification-eligibility score, or a promise of employment. Employers set their own hiring requirements, and certifying bodies set their own eligibility rules. Check with them before you apply.

## What Does a Medical Science Liaison Do?

MSLs are field-based scientific experts who connect a life sciences company with the clinicians and researchers who work in its therapeutic areas.

A medical science liaison (MSL) works in a scientific role within pharmaceutical, biotechnology, medical device, contract research, and other healthcare companies. According to the MSL Society, the primary purpose of the role is to build and maintain peer-to-peer relationships with leading physicians, often called key opinion leaders (KOLs), at major academic institutions and clinics. MSLs also engage with other healthcare professionals. The role began in 1967 at Upjohn, which wanted scientifically trained field staff who could build that kind of rapport.

MSLs work in medical affairs, not sales. A 2021 joint position statement from MSL and medical affairs professional bodies, including the MSL Society and the Medical Affairs Professional Society (MAPS), describes MSLs as medical affairs professionals who interact with experts only in a non-promotional context and who should not have sales targets as performance indicators.

### What MSLs typically do

- **Scientific exchange:** discuss disease areas, unmet needs, and clinical evidence with healthcare professionals, and deliver scientific presentations and education.
- **Insight gathering:** bring what they learn from experts in the field back to internal teams, such as clinical development and market access.
- **Evidence generation:** support company-sponsored studies, investigator-initiated research, and real-world evidence studies, including identifying potential clinical investigators.
- **Medical information:** respond to requests for medical information, including bona fide unsolicited requests about off-label uses, with objective and balanced answers supported by evidence.
- **Internal expertise:** train colleagues on the science and serve as a scientific subject-matter expert on cross-functional teams.
- **Safety reporting:** pass on any adverse event they hear about, following their company's pharmacovigilance procedures.

Day-to-day duties vary by company, therapeutic area, and territory, so read each job description closely.

### Skills and education the role calls for

The MSL Society says a doctorate in the life sciences, such as a PhD, PharmD, or MD, has become the educational standard for the role. The 2021 position statement lists an advanced degree, scientific and technical expertise, and strong communication and interpersonal skills as core requirements, along with business acumen, leadership, data analysis, and digital skills. The assessment below is built around those areas.

## Rate Yourself Across Core MSL Competency Areas

Choose the description that sounds most like you today in each area. Be honest: the goal is to find where to focus, not to score yourself.

**JavaScript is turned off in your browser, so this assessment cannot build your results.** You can still read each area and its descriptions below, and use the development actions further down this page to plan your own roadmap.

In each area, the descriptions run from least to most experience. If you are not sure, choose Not sure yet, and your roadmap will start by helping you find out. Your answers stay in this browser tab: nothing is stored or sent, and your results disappear when you leave or reload the page.

**Scientific and clinical knowledge**

How deeply you understand a disease area, its treatments, and the current evidence.

I have a science or health background, but I have not yet focused on one therapeutic area. I know one therapeutic area well at a textbook level, but I do not follow new studies or guidelines regularly. I follow the literature and treatment guidelines in at least one therapeutic area and can explain where the standard of care is heading. Specialists treat me as a peer in at least one therapeutic area, for example through my clinical practice, publications, or research. Not sure yet I need to look for evidence before I rate this area.

**Clinical data interpretation**

How confidently you read and critique clinical trials and real-world evidence.

I can read a study abstract, but I find study designs, endpoints, and statistics hard to judge. I understand common study designs and endpoints, but I rarely critique a paper's methods or limitations on my own. I regularly critique clinical papers, including their design, statistics, and limitations, for example in journal clubs or my own work. I have designed or analyzed studies, or I teach others how to appraise clinical evidence. Not sure yet I need to look for evidence before I rate this area.

**Scientific communication and presentation**

How clearly you explain complex science to experts and non-experts, in conversation and on slides.

I rarely present science to others, and I am not yet comfortable answering questions in front of an audience. I have given some presentations, such as lab meetings or in-service talks, but I tend to rely on my slides. I present science regularly, adapt my message to the audience, and handle unexpected questions calmly. I have presented at conferences or trained other professionals, and I get consistent feedback that I explain complex data clearly. Not sure yet I need to look for evidence before I rate this area.

**KOL relationship building**

How well you build lasting professional relationships with leading clinicians and researchers, often called key opinion leaders (KOLs).

I have few professional contacts outside my own team or institution. I network at events or online, but I rarely keep in touch with experts after the first conversation. I keep up ongoing professional relationships with clinicians or researchers, and I can describe how I earned their trust. Experts seek me out for scientific discussion or collaboration, and I have built partnerships that lasted over time. Not sure yet I need to look for evidence before I rate this area.

**Compliance and regulatory awareness**

How well you understand the rules that separate scientific exchange from promotion, and the safety reporting duties that come with the role.

I know the pharmaceutical industry is regulated, but I could not yet explain what separates scientific exchange from promotion. I understand the difference between scientific exchange and promotion in general terms, but I have not worked under those rules. I can explain how to handle an unsolicited request for off-label information and how to pass on an adverse event I hear about. I have worked under industry compliance policies or safety reporting procedures, or I have trained others on them. Not sure yet I need to look for evidence before I rate this area.

**Cross-functional and business acumen**

How well you understand how a life sciences company works and how medical affairs collaborates with other teams.

I have not worked in or with a pharmaceutical, biotechnology, or medical device company. I understand the basic stages of drug development, but I am unsure how medical affairs works with teams such as clinical development, marketing, and market access. I have worked with several functions, such as clinical operations, regulatory, or commercial teams, and I understand how their goals differ. I have contributed to a product or program strategy across functions, and I can explain how field insights inform company decisions. Not sure yet I need to look for evidence before I rate this area.

**Field logistics and self-management**

How well you plan your own time, travel, and priorities in a field-based role with little day-to-day supervision.

I am used to structured schedules, and I have not yet managed my own priorities or travel for long periods. I can manage my own schedule, but I have not handled a territory, frequent travel, or remote work over time. I work independently, plan my own priorities and travel, and keep accurate records of my activities. I have managed a territory, a set of accounts, or a remote role over time, and I can show how I planned and tracked my work. Not sure yet I need to look for evidence before I rate this area.

**Credentials and experience**

How your education and experience line up with the MSL job postings you are targeting.

I am still completing my education, or my background is outside the life sciences. I have a science or health degree and some relevant experience, but my background differs from what the postings I am targeting ask for. I have an advanced clinical or science degree, such as a PhD, PharmD, or MD, or substantial clinical or research experience in a therapeutic area. I have an advanced degree and directly relevant experience, such as industry, medical affairs, or therapeutic-area expertise that matches the postings I am targeting. Not sure yet I need to look for evidence before I rate this area.

## MSL Development Actions by Competency Area

## How to Become a Medical Science Liaison

There is no single route into the role. These steps reflect what MSL professional bodies describe as core to the job.

### Build scientific depth

The MSL Society says a life sciences doctorate, such as a PhD, PharmD, or MD, has become the educational standard for the role. Employers set their own requirements, so compare your background with the postings you are targeting. Because the role centers on peer-to-peer scientific exchange with specialists, plan to build real depth in at least one therapeutic area.

### Learn to interpret and communicate evidence

Scientific exchange means discussing study designs, results, and limitations accurately and in balance. The 2021 MSL position statement lists data analysis and strong communication among the skills the role needs. Practice critiquing trials and presenting them to experts and non-experts alike.

### Understand the rules of the role

MSLs work under rules that separate scientific exchange from promotion, and they must pass on adverse event reports. Learn these basics before your first interview; the compliance section on this page summarizes them.

### Build relationships and understand the business

MSLs build lasting relationships with experts and bring field insights back to internal teams. Informational conversations with working MSLs, professional meetings, and cross-functional projects in your current role all help you build these skills.

### Package your experience and apply

Tailor your resume or CV to MSL postings, prepare to present science in interviews, and decide whether a structured course or a certification fits your goals. The self-assessment on this page turns these steps into a personal 30/60/90-day plan.

## Medical Science Liaison Certification and Training

Board certifications for MSLs have different eligibility rules, and neither one is a government license.

### BCMAS (Board Certified Medical Affairs Specialist)

BCMAS is offered by the Accreditation Council for Medical Affairs (ACMA), which describes it as a self-paced online program that ends with a board exam. Its enrollment criteria accept a relevant degree such as an MD, PharmD, PhD, DO, DNP, NP, or PA, or a bachelor's degree plus two years of relevant professional experience, such as pharmaceutical industry, clinical, or research experience. That means people who are not yet MSLs can enroll.

### MSL-BC (Medical Science Liaison Board Certification)

MSL-BC is offered by the MSL Society. Candidates need a bachelor's degree or higher and at least one year of full-time experience as an MSL (or an equivalent title) or leading an MSL team. The MSL Society states that people aspiring to break into the profession are not eligible. The exam is delivered online with remote proctoring, and the certification period is three years.

### Do you need a certification to become an MSL?

Neither certification is a government license, and the MSL Society states that participation in MSL-BC is voluntary. Employers decide whether they ask for any credential, so check the postings you are targeting. This self-assessment does not measure eligibility for either certification.

### MSL training courses

QKC Health's [MSL course](https://qkchealth.com/classes/msl/) is delivered through live, instructor-led sessions you can attend from anywhere with an internet connection. Its curriculum covers KOL engagement, clinical data interpretation, scientific communication, pharmacovigilance, regulatory affairs, and career development, including interview preparation and certification pathways such as BCMAS. Completing any course, including ours, does not guarantee employment, certification, or professional advancement.

## Building a Medical Science Liaison Resume

Translate your clinical or research background into evidence that matches the MSL postings you are targeting.

- **Lead with your scientific focus.** Open with a short summary that names your degree, your therapeutic-area expertise, and the kind of MSL role you want.
- **Show communication with evidence.** List presentations, publications, posters, teaching, and training you have delivered, with the audience for each.
- **Show relationships and influence.** Describe collaborations, partnerships, and committees where you built trust with experts or worked across teams.
- **Mirror each posting honestly.** Use the therapeutic areas, skills, and responsibilities named in a posting where they truly match your experience.
- **Quantify where you can.** Numbers such as studies supported, audiences trained, or projects led help a reader judge the scope of your work.
- **Keep it accurate.** List only degrees, certifications, and results you can verify, and be ready to discuss every line in an interview.

For interview preparation, see the [MSL Interview Toolkit](https://qkchealth.com/resources/msl-interview-toolkit/).

## Compliance Basics for Aspiring MSLs

Compliance is one of the competency areas in the assessment. These are the core ideas to understand before you apply.

- **Scientific exchange, not promotion.** The 2021 MSL position statement says MSLs interact with experts only in a non-promotional context, should not act as product advocates, and should not have sales targets as performance indicators.
- **Unsolicited requests.** The same statement says MSLs may respond to bona fide unsolicited requests for off-label information with objective, balanced answers supported by evidence, should document those requests, and should never use proactive meetings to share off-label information.
- **Adverse event reporting.** The statement says MSLs should report adverse events raised during external interactions within 24 hours, under their company's pharmacovigilance policy. Under FDA's postmarketing reporting rule for drugs (21 CFR 314.80), application holders must promptly review adverse drug experience information from any source and report serious, unexpected adverse drug experiences no later than 15 calendar days after they first receive the information.
- **Sharing scientific information on unapproved uses.** In January 2025, FDA issued guidance on communications in which firms share scientific information about unapproved uses of their approved or cleared medical products with health care providers. FDA's guidance page states that it is not for current implementation while the Office of Management and Budget reviews its information collection. Check the current version and its status on the FDA website before you rely on it.
- **Industry codes and transparency.** The PhRMA Code on Interactions with Health Care Professionals, last updated in August 2021, sets out the pharmaceutical industry's principles for professional interactions with health care professionals. CMS Open Payments is a national disclosure program with a public database of payments that drug and medical device companies make to covered recipients such as physicians.

Each company also has its own policies and standard operating procedures. This summary is general information, not legal or regulatory advice.

## Medical Science Liaison: Frequently Asked Questions

### What is a medical science liaison?

A medical science liaison, or MSL, is a scientific expert who works for a pharmaceutical, biotechnology, medical device, or other healthcare company. According to the MSL Society, the main purpose of the role is to build peer-to-peer scientific relationships with leading physicians, often called key opinion leaders, at major academic institutions and clinics.

### What does a medical science liaison do?

MSLs discuss disease areas and clinical evidence with healthcare professionals, respond to requests for medical information, support clinical research, and share insights from the field with internal teams. A 2021 position statement from MSL and medical affairs professional bodies describes the role as non-promotional, and MSLs must pass on any adverse events they hear about.

### How do you become a medical science liaison?

Start with deep scientific expertise. The MSL Society says a doctorate such as a PhD, PharmD, or MD has become the educational standard for the role. Then build depth in a therapeutic area, practice interpreting and presenting clinical data, learn the compliance rules of scientific exchange, and talk with working MSLs before you apply.

### Can you be a medical science liaison with a master's degree?

Employers set their own requirements, so check each posting. Because the MSL Society describes a doctorate as the educational standard, candidates with a master's degree should be ready to show strong therapeutic-area expertise and relevant clinical, research, or industry experience. This self-assessment can help you see which areas to strengthen.

### Is there a medical science liaison certification?

Yes. The Accreditation Council for Medical Affairs offers BCMAS, whose enrollment criteria accept a relevant advanced or clinical degree, or a bachelor's degree with two years of relevant experience. The MSL Society offers MSL-BC, which requires at least one year of full-time experience as an MSL, in an equivalent role, or leading an MSL team, so aspiring MSLs are not eligible. Neither is a government license.

### Is a medical science liaison part of regulatory affairs?

No. The 2021 MSL position statement describes MSLs as medical affairs professionals. MSLs still need a working knowledge of regulatory and compliance rules, such as how to handle unsolicited requests for off-label information and how to report adverse events.

### Do medical science liaisons travel a lot?

The role began as a field position, and the MSL Society describes MSLs coordinating with other field staff in their territory. Travel expectations vary by employer and territory size, so check what each job posting states.
