PathA masters with a non-science degree. A non-science bachelor’s degree is not a barrier to PathA admission — it’s a fixable gap. Every NAACLS-accredited PathA program accepts applicants with bachelor’s degrees in any field, provided the prerequisite coursework is complete on a regionally accredited transcript. This guide walks through the full prereq stack a non-science applicant needs to add (microbiology, A&P, general and organic chemistry, biochemistry, math, English), maps each course to a self-paced online option, and lays out a 12–18 month timeline from where you are now to a complete PathA application.
Pathologists’ Assistant programs sit in an unusual category in allied health admissions: they want a bachelor’s degree, but they don’t care what the degree is in. Drexel, Quinnipiac, Maryland, Touro, and every other NAACLS-accredited program admit applicants with bachelor’s degrees in English, history, business, art, communications, music, education, philosophy — anything. The single requirement is that the science prerequisite stack be complete by the time of application (or by matriculation, depending on the program).
That structural feature makes PathA one of the most accessible master’s-level allied health credentials for career-changers. You are not penalized for having a non-science bachelor’s. You’re not asked to redo your undergraduate degree. You just need to add the specific science prerequisites — typically 12 to 14 courses spanning biology, chemistry, math, and English — through a regionally accredited institution.
This guide is for that audience: working adults with a non-science bachelor’s degree who want to pursue PathA admission. The path is concrete, the timeline is finite (typically 12 to 18 months), and the cost is dramatically lower than going back for a second bachelor’s degree. This article walks through every course in the stack, links each one to a self-paced online option through Upper Iowa University (HLC accredited), and lays out the realistic project plan from your current transcript to a competitive application.
Start by inventorying your existing transcript. The good news for non-science applicants is that the bachelor’s degree itself is the largest single requirement — you’ve already cleared it. The work that remains is adding the specific science, math, and (sometimes) English coursework that PathA programs require.
That’s typically 11 to 13 courses, totaling 40 to 50 credits. It’s a real project, but it’s a finite one. On self-paced online coursework with two courses running in parallel, the realistic timeline is 12 to 18 months.
This section walks through every course in the typical PathA prerequisite stack with a brief description of why each one matters and a direct link to the self-paced online option through PrereqCourses.com.
The foundation of the biology stack. Every NAACLS PathA program requires General Biology I — most also require II. Take BIO 135 General Biology I first; it covers cellular biology, genetics, evolution, and metabolism — the prerequisite for everything else in the biology chain. Then take BIO 140 General Biology II for organisms, ecology, and physiology. Both are 4 credits with lab. Together they total 8 of your 16+ biology credits.
Required by virtually every PathA program — the field is built around tissue and specimen processing, and microbiology is foundational to understanding tissue infection, contamination, and pathogen identification. BIO 210 Microbiology with Lab covers bacteriology, virology, mycology, immunology, and lab technique. 4 credits with lab. Take it after General Biology I.
The single highest-priority biology course for PathA programs. Pathologists’ Assistants spend their professional lives doing gross anatomic dissection — A&P is the cognitive foundation for the entire profession. Take BIO 270 Human Anatomy & Physiology I (cells, tissues, integumentary, skeletal, muscular, nervous, special senses) and BIO 275 Human Anatomy & Physiology II (endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive). Both are 4 credits with lab.
Required or strongly preferred at virtually every PathA program. Modern pathology is increasingly molecular and genetic — programs want to see Genetics on your transcript as a signal of preparation for the molecular-pathology coursework you’ll encounter in the master’s program. BIO 282 General Genetics covers Mendelian and molecular genetics, gene expression, mutations, and population genetics. Typically 3–4 credits.
Required by every PathA program — the foundation of the chemistry stack. CHEM 151 General Chemistry I covers atomic theory, stoichiometry, thermodynamics, gas laws, and basic equilibrium. CHEM 152 General Chemistry II covers kinetics, advanced equilibrium, acids and bases, electrochemistry, and basic organic introduction. Both are 4 credits with lab. They are prerequisites for every chemistry course downstream.
The chemistry specialization course required in some form at every PathA program. CHEM 251 Organic Chemistry I covers structure, bonding, stereochemistry, alkanes, alkenes, alkynes, alcohols, and basic reaction mechanisms. 4 credits with lab. Some programs (Loma Linda, University of Jamestown) require Organic Chemistry II as well — take CHEM 252 Organic Chemistry II in those cases.
Required outright at programs like Duke and University of Jamestown; strongly preferred at most others. Even at programs where Biochemistry is technically optional, including it on your transcript significantly strengthens your application — molecular pathology is increasingly central to the field. CHEM 330 Biochemistry I covers protein structure, enzymes, carbohydrate metabolism, lipid metabolism, and nucleic acids. Typically 3–4 credits. Take it after Organic Chemistry I.
Required by ~70% of PathA programs and strongly preferred at the rest. MATH 220 Elementary Statistics covers descriptive statistics, probability, hypothesis testing, regression, and the statistical reasoning underlying medical research. 3 credits.
A small number of programs (notably Drexel) require Calculus I as part of the math prerequisite stack. MATH 120 Calculus I covers limits, derivatives, integration, and basic applications. 4 credits. Skip this one unless your specific target programs require it; check program websites carefully.
Required by approximately 60% of PathA programs as part of the bachelor’s degree. Most US bachelor’s degrees already include both as general education. If your bachelor’s transcript shows them, you’ve cleared this requirement. If it doesn’t, you’ll need to add them — but for non-science majors, this is rare. The English-major and humanities-major applicants reading this article almost universally have both already.
Below is the standard 12-month sequence for a non-science applicant building the full prerequisite stack from scratch. The timeline assumes 15–20 hours per week of study, two courses running in parallel, and self-paced online coursework with monthly start dates.
| Months | Courses (in parallel) | Credits | Cumulative |
| Months 1–3 | General Biology I (BIO 135) + General Chemistry I (CHEM 151) | 8 credits | 8 / ~45 |
| Months 3–5 | General Biology II (BIO 140) + General Chemistry II (CHEM 152) | 8 credits | 16 / ~45 |
| Months 5–7 | Microbiology (BIO 210) + Organic Chemistry I (CHEM 251) | 8 credits | 24 / ~45 |
| Months 7–9 | Anatomy & Physiology I (BIO 270) + Biochemistry I (CHEM 330) | 8 credits | 32 / ~45 |
| Months 9–11 | Anatomy & Physiology II (BIO 275) + Genetics (BIO 282) | 7–8 credits | 39–40 / ~45 |
| Months 11–12 | Statistics (MATH 220) + (optional) Organic Chemistry II if needed | 3–7 credits | 42–47 |
The chemistry chain (General Chem I → General Chem II → Organic Chem I → Biochemistry I) and the biology chain (General Biology I → Microbiology and the rest) run in parallel, so they don’t constrain each other. Within each chain, courses are sequenced so prerequisites are satisfied before downstream courses begin. Anatomy & Physiology and Genetics sit in the middle blocks because they have lighter prerequisite dependencies and benefit from study bandwidth that’s been built up by the foundation courses. Statistics fits anywhere — it’s an independent course with no science prerequisite — and is parked at the end primarily so it doesn’t crowd the harder months.
If you can dedicate 25+ hours per week, you can run three courses in parallel for some blocks and finish in 9 months. Most non-science applicants find two-in-parallel sustainable for 12 months and three-in-parallel only for short stretches. Don’t overcommit early — burnout in months 6–8 is more common than burnout in months 1–2.
If 15 hours per week is more than you can commit alongside full-time work and family obligations, the same sequence stretched to 18 months still finishes dramatically faster than a brick-and-mortar evening-class path. You take one course at a time instead of two, and the math works out to roughly 18 months for the full stack. That timeline still fits within a standard PathA application cycle if you start now.
Career-changers with non-science bachelor’s degrees often assume they’ll be at a disadvantage in PathA admissions. The data does not support that assumption. Several structural features actually favor strong non-science applicants.
PathA admissions committees recognize that non-science majors frequently have higher overall GPAs because they didn’t grind through the brutal weeder courses (Organic Chemistry, Calculus II) that depress science-major GPAs. A 3.7 in English and a 3.5 in prerequisite science is a stronger application signal than a 3.3 in biology and a 3.2 in prerequisite science. Programs explicitly note that they evaluate the prerequisite-specific GPA separately from the bachelor’s GPA — and the prerequisite GPA is the one they weight most heavily.
PathA programs apply recency rules to science prerequisites — typically 5 to 7 years. A career-changer who completes Organic Chemistry within 12 months of their application has a more recent, more rigorous, more aligned prerequisite profile than a 2018 biology graduate whose chemistry knowledge is now five years stale. Programs notice. Some explicitly state a preference for recent coursework.
Admissions committees read hundreds of personal statements per cycle. The strongest narratives are the ones that explain a clear, motivated transition into the field. A career-changer who can articulate why pathology specifically (often through shadowing experience), how their non-science background contributes (writing skills, project management, attention to detail), and what they’ve already done to prepare (the prerequisite coursework itself) has built a distinctive narrative arc that traditional pre-PathA biology majors cannot match.
Most PathA programs strongly recommend or require shadowing hours with practicing pathologists or pathologists’ assistants. The shadowing requirement applies equally to all applicants — your non-science background does not disadvantage you here. In fact, several program directors have publicly stated that career-changer applicants are sometimes more thoughtful about their shadowing experience because they’ve done it more deliberately.
The cost question is often the largest mental barrier for career-changers considering PathA. The actual numbers are far more favorable than most applicants assume.
PrereqCourses.com science courses are roughly $675–$695 per 4-credit course (inclusive of lab). Math and non-science courses are similar. The full PathA prerequisite stack — 12 courses for a non-science applicant — runs roughly $8,000 to $9,500 total. Add Organic Chemistry II if your target programs require it ($695), and you’re at ~$10,000 for the maximally complete stack.
A second bachelor’s at a state university (in-state tuition) is typically $25,000–$40,000 over 2–3 years. At a private university, $80,000–$160,000 over 2–3 years. A formal post-baccalaureate pre-health certificate program is $20,000–$50,000 over 1–2 years. The self-paced online prerequisite path is between 50% and 90% cheaper, and dramatically faster — 12 to 18 months versus 2 to 3 years.
Community college is the only path that competes on raw per-credit price ($150–$300 per credit for in-district residents). Total tuition for 40+ credits runs $6,000–$12,000 — sometimes lower than self-paced online. The trade-off is structural: community college labs run on fixed semesters, often have waitlists for the most-demanded science courses (A&P, Microbiology), and the time-to-completion stretches to 24–36 months for a non-science applicant taking evening classes alongside full-time work. The cost of an extra year before PathA matriculation is roughly equal to one year of foregone PathA salary, which more than offsets any tuition savings.
“Introduction to Biology,” “Survey of Chemistry,” “Concepts of Biology,” “Biology for Non-Majors,” “Life Science” — these are all non-majors survey courses, and PathA programs reject them. The catalog description is the diagnostic: if it includes “designed for non-science majors,” “general education science requirement,” or “for the liberal arts student,” the course will not satisfy the prerequisite. Take majors-level General Biology I, General Chemistry I, etc., from a regionally accredited four-year university.
Most PathA programs accept community college coursework for lower-division prerequisites (General Biology, General Chemistry). Some programs prefer or require that upper-division coursework (Genetics, Biochemistry, sometimes A&P) come from a four-year institution. Self-paced online coursework from a regionally accredited four-year university (Upper Iowa University via PrereqCourses.com is HLC accredited) eliminates this risk entirely — every credit issues from a four-year university transcript.
Every PathA program requires a chemistry specialization beyond General Chemistry I and II. Some accept Organic Chemistry only, some accept Biochemistry only, some require both. The safe path for a non-science applicant applying to multiple programs is to take both Organic Chemistry I and Biochemistry I — the marginal cost of one additional course (~$695) is far less than the cost of being filtered out at a top-choice program because you took only one and they wanted the other.
A&P I and II are typically the two most demanding courses in the prerequisite stack — they cover an enormous amount of material at significant depth, and the lab component is rigorous. Career-changers without recent science coursework sometimes underestimate the time investment and end up rushing through them. Plan for A&P I and II to be among the harder months in your timeline; sequence them when you have stable bandwidth.
Shadowing should run in parallel with your prerequisite coursework, not after. Pathology departments often have waitlists for shadowing slots; some require an introductory call with the program coordinator. Start the shadowing pipeline in Month 1 — by the time you complete your prerequisites, you should have 40 to 80+ shadowing hours documented and a recommendation letter from the supervising pathologist or PathA. This is the single most-cited application strengthener in PathA admissions.
Yes. Every NAACLS-accredited PathA program accepts bachelor’s degrees in any field — the requirement is that the degree be earned at a regionally accredited US institution. The AAPA program directory confirms this across all 16 US programs. The science prerequisites are what gates admission, not the major.
Generally no for non-science general education (English Composition, history, etc.). PathA programs apply recency rules to science prerequisites specifically — typically 5–7 years for biology and chemistry. The bachelor’s degree itself doesn’t expire. If your science prerequisites are older than the recency window, retake those specific courses; everything else on your old transcript stays valid.
Most PathA programs evaluate three GPAs: cumulative undergraduate GPA, prerequisite (science-specific) GPA, and the most recent 60 credits. A non-science applicant typically has a strong cumulative GPA (because their major was less GPA-depressing than science), and PathA admissions committees note this explicitly. The prerequisite GPA — your performance in the courses you took specifically as PathA prep — is weighted most heavily and is the primary differentiator.
GRE requirements have shifted significantly since 2020. A growing number of PathA programs (Touro, Wayne State, several others) now waive the GRE entirely. Others (Maryland, Loma Linda) still require or strongly recommend it. Check each of your target programs’ current policy on their official website. If half your target programs require the GRE, taking it is the path of least resistance — a strong GRE score is rarely a disadvantage even at programs that don’t require it.
Most PathA programs allow applications with up to 1–2 prerequisites in progress at the time of submission, with the requirement that they be completed before matriculation. Maryland, Drexel, and Wayne State explicitly accept this; Loma Linda and Duke prefer all prerequisites complete at submission. If your stack is mostly complete with 1–2 courses left, applying with those in progress can save you a full application cycle.
Shadowing is the single most-cited application strengthener for PathA admissions. For non-science applicants, it’s even more important — it’s how admissions committees verify that your interest in the field is informed and serious rather than abstract. Plan for 40 to 100+ shadowing hours documented through the application cycle, ideally with a recommendation letter from the supervising pathologist.
If your local hospital pathology department is closed to shadowing, broaden your search: medical examiner offices, forensic pathology departments, university teaching hospitals, regional medical centers, and AAPA member outreach. Some PathA programs (Touro, Tulane) maintain lists of partner pathology practices that accept pre-PathA shadowing — email program coordinators directly to ask. The AAPA also publishes a member directory; reaching out cold to practicing PathAs in your region is more often successful than applicants assume.
A non-science bachelor’s is not a barrier to PathA admission. It is a fixable gap. The work is concrete: 11 to 13 prerequisite courses spanning biology, chemistry, math, and (sometimes) English, all available through self-paced regionally accredited online coursework. The timeline is 12 to 18 months for the full stack. The cost is roughly $8,000 to $10,000 — dramatically less than any post-baccalaureate program or second bachelor’s degree.
Career-changers with non-science backgrounds can be genuinely competitive at PathA admissions. Strong non-science cumulative GPAs, recent rigorous prerequisite coursework, distinctive personal-statement narratives, and serious shadowing histories combine to produce applications that match or exceed what traditional biology-major applicants can offer. The structural features that scare most non-science majors away from medical school admission do not apply to PathA in the same way.
The path forward is not complicated. Map your existing transcript against the prerequisite list. Identify the gaps. Enroll in the courses that close the gaps. Run the chemistry and biology chains in parallel. Shadow throughout. Apply at the end of the first cycle in which all your prerequisites will be complete. The math works.
If you’re starting the full PathA prerequisite stack from a non-science bachelor’s, the typical Month 1 enrollment is BIO 135 General Biology I and CHEM 151 General Chemistry I in parallel. Then advance through the full sequence: BIO 140, CHEM 152, BIO 210 Microbiology, CHEM 251 Organic Chemistry I, BIO 270 A&P I, CHEM 330 Biochemistry I, BIO 275 A&P II, BIO 282 Genetics, and MATH 220 Statistics. The free Advisory Service maps your existing transcript against your specific PathA target programs and flags exactly which courses are required. New advisory sessions begin on the 1st of every month.
