PrereqCourses vs. Portage Learning for MLS Prerequisites: A Head-to-Head Comparison –an honest comparison between the two best-known regionally accredited online prerequisite providers — focused on what actually matters for clinical lab science applicants.
Both PrereqCourses and Portage Learning are legitimate, regionally accredited providers of online prerequisite courses, and both have track records of credit acceptance at clinical lab science programs. They differ in five things that genuinely matter: course naming and rigor framing, per-credit pricing, start-date structure, partner-institution accreditation tier, and MLS-specific course alignment. For most clinical lab science applicants — MLS, MLT, PathA, histotech — PrereqCourses tends to be the safer choice because of how courses are titled and the partner-institution profile. Portage is competitive on price and rolling start dates, and is widely accepted at nursing and pre-health programs more broadly.
| Bottom line If you’re applying to an MLS or NAACLS-accredited clinical lab program specifically, PrereqCourses’ course titles and majors-level framing are the lower-risk choice — programs are increasingly cautious about “Essential” or survey-tier courses. If you’re applying to nursing or general pre-health, both providers work. Either way, verify acceptance with your specific target program before enrolling — that single conversation prevents 90% of credit-rejection problems. |
Founded around 2000 and based in Beaver Falls, Pennsylvania, Portage Learning is one of the longest-running online prerequisite course platforms in the U.S. The company partners with two regionally accredited institutions — Geneva College (accredited by the Middle States Commission on Higher Education) and Bushnell University (accredited by the Northwest Commission on Colleges and Universities). Geneva issues credits and transcripts for most students nationally; Bushnell issues credits for students in Alaska, California, Hawaii, Idaho, Oregon, and Washington. Portage Learning itself is also separately accredited by the Middle States Commission on Secondary Schools.
Portage’s strengths are real: 25+ years in the space, faculty-graded coursework, immediate enrollment (“register today, start tomorrow”), and a wide course catalog covering biology, chemistry, math, psychology, English, and humanities. Portage publishes that its students have transferred credits to more than 2,800 colleges and universities — a sizable footprint.
PrereqCourses delivers self-paced online prerequisite courses through a partnership with Upper Iowa University — a regionally accredited private nonprofit institution founded in 1857 and accredited by the Higher Learning Commission (HLC). HLC is the same regional accreditor that covers most large state universities and Big Ten institutions in the Midwest, including the academic homes of many NAACLS-accredited MLS programs. PrereqCourses courses appear on Upper Iowa University transcripts, which transfer reliably to other regionally accredited institutions.
PrereqCourses’ positioning emphasizes course-specific alignment with named clinical lab credentials — MLS, MLT, PathA, histotech — and majors-level course framing rather than “Essential” or survey-tier nomenclature. The course list is narrower than Portage’s overall catalog, but more directly mapped to clinical lab program prerequisite requirements.
The table below compares the two providers across the five factors that meaningfully affect MLS applicants. Cells that meaningfully favor one provider are noted; cells where the two are roughly equivalent are flagged as such.
| Factor | PrereqCourses (Upper Iowa University) | Portage Learning (Geneva / Bushnell) |
| Regional accreditation | Higher Learning Commission (HLC) — covers Midwest and beyond, including academic homes of many MLS programs | Middle States Commission on Higher Education (Geneva); Northwest Commission (Bushnell, for 6 western states) |
| Course catalog focus | Narrower; explicitly mapped to MLS/MLT/PathA/histotech prerequisite requirements | Broader; covers nursing, pre-health, general college credit needs across many fields |
| Course naming | Standard university nomenclature (BIO 210 Microbiology with Lab; BIO 270 Human Anatomy & Physiology I; CHEM 251 Organic Chemistry I) | Mix of “Essential” titled courses (BIOD 171 Essential Microbiology) and recently introduced majors-level (BIOL 271 Microbiology); naming varies by partner institution |
| Per-credit pricing (2026) | $695 for 4-credit courses ($173.75/credit); $675 for 3-credit courses ($225/credit) | $223/credit hour, all courses; 4-credit courses = $892, 3-credit courses = $669 |
| Net cost: 4-credit science course | $695 | $892 |
| Net cost: 3-credit course | $675 | $669 |
| Start dates | Monthly — courses begin on the 1st of each month | Rolling — register today, start tomorrow |
| Pace | Self-paced; assignment-based; most students finish in 6–12 weeks | Self-paced with a 28-day minimum and a 48-hour wait between exams; most students finish in 4–8 weeks |
| Lab format | Virtual labs and interactive simulations integrated with lecture courses | Virtual labs and interactive simulations with proctored online exams |
| Faculty model | Course faculty assigned through Upper Iowa University; instructor support via course platform | Dedicated professor per course with one-to-one student access; proctored exams |
| Transcript | Issued by Upper Iowa University; HLC-accredited transcript | Issued by Geneva College or Bushnell University depending on student state of residence |
| MLS program track record | Course offerings explicitly mapped to ASCP Route 2 and NAACLS MLS program prerequisites | Strong nursing/pre-health acceptance; MLS-specific acceptance varies by program — verification required |
This is the single most important factor for MLS-specific applicants, and it’s the one most prospective students miss. Portage’s biology offerings include both an “Essential”-titled track (BIOD-prefix) — BIOD 101 Essential Biology I, BIOD 151 Human Anatomy & Physiology I, BIOD 171 Essential Microbiology — and a majors-level track (BIOL-prefix) with the same content under different course numbers (BIOL 101, BIOL 251, BIOL 271). Both are accredited; both transfer to many institutions.
The challenge for MLS applicants is that NAACLS-accredited programs sometimes scrutinize “Essential” course titles because the naming convention historically signals survey-level for non-science majors, which doesn’t satisfy the rigor expectations of most MLS programs. The Portage “Essential” content is in fact strong — student feedback consistently calls the courses rigorous — but the title alone can trigger registrar scrutiny that pushes the application back into the prerequisite-clarification queue.
PrereqCourses uses standard university course nomenclature throughout: BIO 210 Microbiology with Lab, BIO 270 Human Anatomy & Physiology I, CHEM 251 Organic Chemistry I. No “Essential” framing, no survey-vs-majors ambiguity. For an MLS applicant whose registrar is reviewing a transfer transcript, this is the lower-friction signal.
| Practical advice: if you choose Portage for MLS prerequisites, take the BIOL-prefix versions (BIOL 271, BIOL 251, BIOL 252), not the BIOD-prefix “Essential” versions. Confirm with your target MLS program’s registrar in writing that the specific Portage course you plan to take satisfies the prerequisite. Save the email. |
Portage prices at $223 per credit hour, flat. PrereqCourses prices courses individually: 4-credit science-with-lab courses are $695 (= $173.75/credit), 3-credit courses are $675 (= $225/credit). For the 4-credit science-with-lab courses that make up most of an MLS prerequisite stack, PrereqCourses is materially cheaper — $695 versus $892 per course is a savings of $197 per course, or roughly 22%.
Across an 8-course MLS prerequisite stack (5 four-credit science courses + 3 three-credit courses):
Both providers are dramatically cheaper than community college transfer credit (often $400–$800/credit at out-of-state rates) or university extension programs ($800–$1,500/credit).
Portage’s “register today, start tomorrow” model is a real advantage if you’re racing a deadline. PrereqCourses’ courses begin on the 1st of each month — meaning if you register on the 3rd, you wait until the 1st of next month to begin. Net delay: up to 28 days.
Where the timing trade-off changes direction: Portage requires a 28-day minimum between course start and earliest possible completion, plus a 48-hour wait between exams. PrereqCourses has no minimum duration — students who commit fully can finish a 4-credit course in 4–6 weeks. The net practical timeline for completing one course is often comparable across the two providers, though Portage’s faster start is meaningful when you’re already past a deadline.
If you have a hard application deadline within 30 days, Portage’s earlier start will sometimes mean the difference between making the deadline and not. If you’re planning a 6–12 month prerequisite sequence, the start-date difference is essentially irrelevant.
Both providers’ partner institutions are regionally accredited — the gold standard for transfer credit. The differences are subtle but real:
In practical terms: regional-to-regional transfer credit is accepted at the great majority of clinical lab programs regardless of which regional accreditor is the source. The accreditation-tier differences show up only at the margins, and only when a specific MLS program has institutional preferences for credit from same-accreditor schools.
Portage’s catalog is broader. They offer Genetics, Pathophysiology, Pharmacology, Neuroscience, Medical Terminology, Nutrition — useful for nursing applicants, sometimes useful for MLS applicants depending on program-specific requirements. PrereqCourses’ catalog is narrower but more directly clinical-lab-aligned.
For the core MLS prerequisite stack — biology, microbiology, chemistry, organic chemistry, biochemistry, A&P, statistics — both providers offer all of these courses. Coverage of the standard ASCP Route 2 framework is equivalent.
Where the alignment differs: PrereqCourses’ marketing and course descriptions explicitly reference NAACLS, ASCP Route 2, and MLS-specific applications. Portage’s course descriptions are written more generically for nursing and pre-health audiences. For an MLS applicant whose program registrar is checking the syllabus against ASCP Route 2 requirements, the course description’s explicit MLS framing reduces evaluation friction.
This article is on the PrereqCourses website, but credible comparison articles acknowledge when the competitor is the right answer. There are real cases:
Application deadline is in 25 days, you need a course done before submission, and you can’t wait for the 1st of the month. Portage’s immediate-start model wins this scenario. The course content is comparable; the start date is the constraint.
Portage has a deeper and longer track record at nursing schools, ABSN programs, and general pre-health pathways than at NAACLS-accredited MLS programs specifically. If MLS isn’t your target — if you’re hedging across nursing, PA, or pre-med — Portage’s wider acceptance and broader catalog are advantages.
Pathophysiology, Pharmacology, Nutrition, and Neuroscience are on Portage’s list and not directly on PrereqCourses’. If your target program requires one of these specifically, Portage is the natural choice. (For MLS specifically, none of these is a standard prerequisite.)
Portage’s faculty model — a dedicated professor per course with explicit one-to-one student access — is genuinely strong, particularly for students returning to school after years away who want hand-holding through difficult material. PrereqCourses provides instructor support but doesn’t market the same dedicated-faculty model. If you know you’ll need active instructor engagement, Portage’s model may fit better.
This is the case the article was written to address. Course naming, ASCP Route 2 alignment, and the HLC accreditation tier are all small advantages individually that compound into materially smoother registrar evaluation for clinical-lab-specific applications.
If you’re taking 5+ four-credit science-with-lab courses (which is most of the ASCP Route 2 stack), the $197/course savings adds up. Across the typical 8-course MLS prerequisite stack, PrereqCourses saves roughly $967 — about 15% of total cost. For students paying out of pocket, that’s real money.
If you’re a Labcorp, Quest, ARUP, hospital, or other clinical lab employee using tuition reimbursement to fund prerequisites, PrereqCourses’ explicit ASCP Route 2 framing makes the reimbursement request easier to approve. The HR conversation goes faster when the course title and course description match the certification requirement word-for-word.
Some students prefer monthly start dates because the structure helps with discipline. Knowing your course begins on the 1st creates a deadline-driven start; Portage’s “register today” can be paradoxically harder for students who procrastinate when no fixed deadline exists. This is taste-driven, but the monthly cadence works better for many adult learners juggling work and study.
Both providers are regionally accredited and widely accepted. Neither is bulletproof. The risks below apply to both:
NAACLS-accredited MLS programs each set their own transfer credit acceptance policies. Some accept all regionally accredited credit; some have specific institutional preferences; a small minority restrict transfer credit narrowly. Neither provider can guarantee acceptance at a specific program — only the program itself can. Always confirm in writing with your target program’s registrar before enrolling.
Online science courses with lab face more scrutiny than online lecture-only courses at most NAACLS-accredited programs. Both PrereqCourses and Portage use virtual labs with interactive simulations. Acceptance is good but not universal. If your target program explicitly requires “hands-on wet lab” experience, neither provider’s online lab will satisfy.
Both providers have strict refund policies — once you enroll, the money is generally not recoverable even if the credit isn’t accepted by your target program. This is the strongest case for verifying acceptance before enrolling. The two-line email exchange with your program’s registrar is the most valuable risk mitigation available.
PathA and some MLS programs apply recency rules to prerequisite courses — typically 5 to 10 years. Online prerequisite credits don’t escape recency rules. If your target program has a 5-year recency window on biology and chemistry, plan to take the prerequisite within that window before your application date.
Before clicking enroll on either platform, send your target program’s registrar this email. Five minutes of work prevents most credit-rejection problems:
| Sample registrar verification email Subject: Transfer credit verification — [course name] “I’m a prospective applicant to your [program name] for the [intake cycle]. I’m planning to complete a prerequisite course online before my application is due and want to confirm acceptance before enrolling. The course is [BIO 210 Microbiology with Lab / BIOL 271 Microbiology with Lab], a 4-credit course offered through [PrereqCourses.com via Upper Iowa University, regionally accredited by HLC / Portage Learning via Geneva College, regionally accredited by MSCHE]. The course includes a virtual lab component. Will this course satisfy your microbiology prerequisite for the [program name]? If not, can you let me know what would be acceptable so I can plan accordingly? Thank you for your time.” |
Save the response. If the registrar confirms acceptance and the course is later questioned during the application review, the email is your protection.
Yes. PrereqCourses transcripts come from Upper Iowa University, accredited by the Higher Learning Commission. Portage Learning transcripts come from either Geneva College (MSCHE) or Bushnell University (NWCCU), depending on student state of residence. All three accreditors are recognized by the U.S. Department of Education and the Council for Higher Education Accreditation.
Most NAACLS-accredited MLS programs accept regionally accredited transfer credit, including from both providers. Acceptance varies program-by-program — some programs are pickier than others, particularly about online lab credits and “Essential”-titled courses. Always verify in writing with your target program before enrolling.
PrereqCourses, by roughly $967 across the typical 8-course MLS prerequisite stack — primarily because PrereqCourses’ 4-credit science-with-lab courses ($695) are meaningfully cheaper than Portage’s ($892). The 3-credit courses are roughly equivalent.
Portage starts faster (immediate enrollment vs. 1st-of-month). PrereqCourses can finish faster (no 28-day minimum, no 48-hour wait between exams). Net practical timeline depends on your enrollment date and study pace. For a typical 6–12 month prerequisite sequence, the difference is negligible.
No — both use virtual labs with interactive simulations. If your target program explicitly requires hands-on wet lab experience (some PathA programs do), neither online provider satisfies. In those cases you’ll need to schedule lab work at a brick-and-mortar institution.
Yes. Both providers issue independent transcripts (Upper Iowa University from PrereqCourses; Geneva or Bushnell from Portage). Your MLS program will see both transcripts and evaluate the courses independently. Some students do this — taking the courses Portage doesn’t offer at PrereqCourses, and vice versa. The mechanics work fine.
PathA programs generally accept regionally accredited transfer credit, but PathA admissions are extraordinarily competitive (8–15 admits per program from 200+ applications). Some PathA programs prefer prerequisites taken at four-year universities over online providers. Confirm acceptance with each PathA program before enrolling. Both providers’ regionally accredited transcripts work; the safer path is direct verification.
Yes for both, generally. Reimbursement programs care about regional accreditation and job-relatedness — both providers satisfy both criteria. For employer-billing arrangements (where the employer pays the school directly rather than reimbursing the employee), individual program terms differ; ask your benefits coordinator.
Both PrereqCourses and Portage Learning are credible, regionally accredited online prerequisite providers. Portage has the longer track record overall, the broader catalog, and the immediate-start advantage. PrereqCourses is materially cheaper for the typical MLS science prerequisite stack, uses standard university course nomenclature that registrars evaluate more cleanly, and is more directly aligned with ASCP Route 2 and NAACLS requirements.
For nursing or general pre-health, the choice is reasonable either way and often comes down to start-date timing. For MLS, MLT, PathA, histotech, and other NAACLS-accredited clinical lab credentials specifically — the use case this article was written for — PrereqCourses tends to be the lower-friction, lower-cost choice, with the trade-off that you’ll wait up to 28 days for your first course to begin.
Whichever you choose, the verification step matters more than the provider choice. Confirm acceptance with your target program’s registrar in writing before you enroll. That single conversation prevents almost every transfer-credit problem prospective MLS students encounter.
