Texas ADN prerequisites and the common course numbers, explained
By the team. Checked 15 Nov 2026.
The short answer
Texas ADN prerequisites are listed by common course number. BIOL 2401 and 2402 are Anatomy and Physiology I and II with lab, BIOL 2420 is Microbiology, PSYC 2314 is Lifespan Growth and Development. Austin Community College's ADN asks for 2401, 2402, 2420 and HPRS 2300 Pharmacology, with a C or better. Courses from elsewhere are matched to these numbers.
What the numbers mean
Texas public colleges share a common course numbering system. The four letters are the subject, the first digit is the level (1 for first year, 2 for second year), the second digit is the credit hours, and the last two digits identify the course. So BIOL 2401 is a second-year, four-credit biology course: Anatomy and Physiology I with its lab.
| Number | Course | Credits |
|---|---|---|
| BIOL 2401 | Anatomy and Physiology I (lecture and lab) | 4 |
| BIOL 2402 | Anatomy and Physiology II (lecture and lab) | 4 |
| BIOL 2420 or 2421 | Microbiology | 4 |
| HPRS 2300 | Pharmacology for Health Professions | 3 |
| PSYC 2314 | Lifespan Growth and Development | 3 |
| PSYC 2317 or MATH 1342 | Statistics | 3 |
One example: Austin Community College
ACC's Traditional Track ADN page for the 2026-27 degree plan lists BIOL 2401, BIOL 2402, BIOL 2420 (or 2421) and HPRS 2300 as prerequisites. BIOL 2402 and BIOL 2420 must be completed within five years of the application deadline. Grades of C or better count, the prerequisite GPA must be at least 2.7, and all prerequisites must be done by the deadline.
How a course from somewhere else is matched
When you bring a course from another college, the ADN programme looks for an equivalent: same subject, similar content, similar credits, and a lab if the Texas course has one. A 3-credit A&P lecture with a separate 1-credit lab can match BIOL 2401, as the BIOL 2304 plus 2101 option shows. ACC asks for transcripts from every school you attended other than ACC.
- Same subject and content
- Similar credit hours
- Lab included where the Texas course has one
- Inside the time limit
A checklist before you apply to an ADN programme
Most ADN applications in Texas follow the same pattern, so a short checklist saves you from late surprises. Work through it for each programme on your list, because the details differ even when the course numbers match.
Keep a simple table with one row per prerequisite and one column per programme. Fill in the grade you earned, the date you finished and whether the programme has confirmed it in writing. Gaps then show at a glance.
- Download the current prerequisite sheet for the year you apply
- Check each course against its common course number
- Check time limits against the deadline, not today's date
- Order official transcripts from every school you attended
- Get written answers for any course from outside Texas
Why lab pairing matters
Many online providers split lecture and lab, which is the form UPI Study uses: A&P I is one course and A&P I Lab is another. Texas community colleges also allow that form, with BIOL 2304 lecture plus BIOL 2101 lab standing in for BIOL 2401. Ask your programme whether it will pair a lecture course and a lab course from outside Texas the same way, and ask how it judges an online lab.
Using UPI Study courses for ADN prerequisites
UPI Study offers A&P I and II with labs, Statistics and Introduction to Psychology with ACE-recommended or NCCRS-recommended credit, but no Microbiology or Pharmacology. These would need to appear via a college transcript first; TESU, UoPeople and Newlane are partner colleges that consider such credit. The ADN programme then decides whether each transcript course matches its number. Ask it in writing before you enrol.
What to ask in writing
Before you enrol
Email the nursing programme's admissions office with the course description and syllabus and ask in writing whether it will count for the named prerequisite, before you enrol.
UPI Study is not a college and is not accredited. ACE and NCCRS review our courses and recommend credit; a college decides whether to give that credit and records it on its own transcript.
ACE and NCCRS have over 2,100 cooperating colleges that will consider accepting credits; the final decision is with the universities.
Questions people ask
What is BIOL 2401 in Texas?
Anatomy and Physiology I, a four-credit second-year biology course with lecture and lab under the Texas common course numbering system. Many Texas ADN programmes list it first among prerequisites, and a course from outside Texas is usually compared with it for content, credits and lab work.
Can BIOL 2421 replace BIOL 2420 for nursing?
At Austin Community College, yes: its ADN page says BIOL 2421 may be accepted in place of BIOL 2420. Other programmes set their own rules, so check the prerequisite sheet for yours.
What GPA do I need for Texas ADN prerequisites?
It varies. Austin Community College asks for a prerequisite GPA of at least 2.7 with grades of C or better. Many programmes rank applicants, so the GPA that gets a seat may be higher than the minimum.
