Nursing Prerequisites for Engineers and STEM Professionals Changing Careers-
coming to nursing from engineering or another STEM field? You’ve likely already cleared the math and chemistry — here’s what’s left.

Quick answerEngineers and STEM professionals usually arrive with several nursing prerequisites already satisfied — typically college math or statistics, and often general chemistry. What’s most commonly missing is the human-biology core (anatomy and physiology I and II, microbiology) and sometimes the social-science requirements (psychology, sociology). The catch for career changers is recency: if your STEM coursework is more than 5–7 years old, many programs will require you to retake the science prerequisites. Completing what you’re missing online and self-paced is usually the fastest route in.

If you’re an engineer, chemist, data analyst, or other STEM professional considering a move into nursing, you have a real head start — and a couple of specific blind spots. Your background means you’ve almost certainly handled the quantitative and physical-science coursework that intimidates many applicants. But nursing prerequisites are weighted toward human biology, and that’s where STEM career changers usually have ground to make up.

This guide is specific to your situation: what your STEM background likely already covers, what you still need, and how the recency rule affects credits you earned years ago. It builds on our broader guide to nursing prerequisites for career changers — start there for the full picture, then use this for the STEM-specific details. For background on the profession, see the American Association of Colleges of Nursing (AACN).

What your STEM background likely already covers

Nursing programs require a mix of science, math, and general-education prerequisites. A STEM degree typically clears several of them outright:

• College math and statistics. Engineers and most STEM majors have calculus and often statistics — and statistics is increasingly the math nursing programs require. This is frequently your strongest area of overlap.
• General chemistry. Many STEM programs require general chemistry with a lab, which can satisfy a nursing chemistry prerequisite — subject to recency and content matching.
• English composition. A bachelor’s degree usually includes the required college writing.
• Physics (a bonus, not usually required). Nursing rarely requires physics, but it signals quantitative readiness and won’t hurt your application.

If you hold a bachelor’s degree and are eyeing an accelerated second-degree BSN (ABSN), you’ll also skip most general-education requirements — your degree covers them. That narrows your remaining work mostly to the science prerequisites below.

What you most likely still need

Here’s where STEM career changers concentrate their effort — the human-biology core that engineering and physical-science degrees usually don’t include:

Prerequisite	Why STEM grads usually need it
Anatomy & Physiology I and II	The most heavily weighted nursing science, almost always required with a lab — and rarely part of a STEM curriculum.
Microbiology	Commonly required with a lab; engineering and most physical-science degrees don’t include it.
General/lifespan psychology	General psychology and developmental (lifespan) psychology are common requirements STEM grads often haven’t taken.
Sociology	Required by some programs; another social science outside a typical STEM track.
Nutrition	Required by some programs.

The pattern is consistent: your gap is biology and the social sciences, not math or chemistry. That’s good news — the human-biology courses are well-defined, and you can complete them online and self-paced while you plan your transition.

The recency trap for STEM career changers

Here’s the issue that catches experienced professionals off guard. Even where your old coursework would satisfy a requirement on paper, many nursing programs require the science prerequisites to have been completed recently — commonly within the last 5 to 7 years, and some as strict as 3.

For a STEM career changer, that has two consequences:

• Your old chemistry may have expired. If you took general chemistry a decade ago for your engineering degree, a program may not accept it now — even though you clearly know the material.
• Math and gen-eds usually hold up. Statistics, English, and other general-education credits typically have no recency limit, so those usually still count.

The fix is faster than you thinkIf an expired science prerequisite is your only gap there, retaking it online and self-paced is quick — and many programs count the highest grade earned, so a strong retake can also lift your science GPA. See our guide to nursing prerequisite recency rules to check your specific situation.

Why self-paced is the right fit for working STEM professionals

You’re likely still working a demanding job while you plan this change. Self-paced online prerequisites are built for exactly that:

• Learn around your job. Work through material on your own schedule rather than fitting a fixed campus class around full-time work.
• Move at your own pace. As a STEM professional, you may move quickly through quantitative content and spend more time on the biology that’s new to you.
• Regionally accredited and transferable. PrereqCourses.com courses are delivered through HLC-accredited Upper Iowa University, the standard nursing programs expect for transfer credit.

Your step-by-step plan

1. Map your transcript against a target program. List what your STEM degree already satisfies and what’s missing or expired.
2. Check the science recency window. Flag any chemistry or other science older than your program’s limit for retaking.
3. Prioritize the biology core. Anatomy and physiology and microbiology are usually your biggest gap and most heavily weighted — start there.
4. Complete online and self-paced. Knock out the missing courses around your job, confirming acceptance with your target program.
5. Consider the ABSN route. With a bachelor’s already in hand, an accelerated second-degree BSN may be your fastest path once prerequisites are done.

Frequently asked questions

What nursing prerequisites do engineers usually already have?

Most commonly college math or statistics and often general chemistry, plus English composition from a bachelor’s degree. Statistics in particular is frequently the exact math nursing programs require.

What will I most likely still need?

The human-biology core — anatomy and physiology I and II, and microbiology — which STEM degrees rarely include, plus social sciences like general and developmental psychology and sometimes sociology or nutrition.

Will my old chemistry credit still count?

Maybe not. Many nursing programs require science prerequisites completed within 5–7 years. If your chemistry is older, you may need to retake it, even though you know the material. General-education credits usually don’t expire.

Is an accelerated BSN a good fit for STEM career changers?

Often yes. If you already hold a bachelor’s degree, an ABSN lets you skip most gen-eds and focus on nursing coursework — once your science prerequisites are complete and recent.

Can I complete the missing prerequisites online?

Yes. Most nursing programs accept online prerequisites from regionally accredited institutions. Self-paced courses let you complete them around a demanding STEM job. Confirm acceptance with your target program.

Bottom line

As a STEM professional, you’re closer to nursing school than you might think — your quantitative and chemistry background clears prerequisites that stop many applicants. Your work is concentrated in the human-biology core (anatomy and physiology, microbiology) and a few social sciences, with the main wrinkle being recency: science credits older than 5–7 years often need refreshing. Map your transcript against a target program, retake any expired science, complete the missing courses online and self-paced, and — if you hold a bachelor’s — consider an accelerated BSN. You can make this change without stepping away from your current job.
