Nursing School Prerequisites: Your Complete 2026 Guide

    Yes, you absolutely need nursing school prerequisites to even be considered for admission. These aren’t just administrative hurdles; they’re the essential building blocks that prepare you for the rigorous demands of nursing education and ultimately, patient care. Think of them as the foundation of a house—without them, everything else would crumble. In this comprehensive guide, you’ll discover exactly which courses you need, how different programs compare, and how to strategically complete your requirements to become the strongest possible nursing school applicant.

    Why Prerequisites Are More Than a Hurdle

    We’ve all been there—excited about nursing school, only to feel overwhelmed by the long list of required courses. But here’s the thing: these prerequisites exist for crucial reasons that directly impact your future competence as a nurse. They provide the scientific foundation you’ll draw on every single day in clinical practice.

    When you’re assessing a patient’s lab results, you’ll need that chemistry background. When you’re understanding disease processes, anatomy and physiology become your roadmap. These courses ensure you can handle the accelerated pace of nursing programs without being left behind. Research consistently shows that students who complete strong prerequisite programs have higher success rates in nursing school and better NCLEX pass rates.

    Clinical Pearl: Many nursing students report that their toughest nursing courses weren’t the nursing-specific ones, but rather the advanced pathophysiology and pharmacology classes that directly build on prerequisite knowledge. Mastering these foundations now pays dividends later.

    Breaking Down Common Prerequisites by Category

    Let’s break down exactly what you’ll typically encounter on your prerequisite journey. While specific requirements vary by program, most US nursing schools align closely with these categories and courses.

    Science Requirements

    The science prerequisites form the core of your nursing foundation. These courses typically require labs and account for the majority credits you’ll complete. Almost every nursing program, from ADN to BSN, requires:

    • Human Anatomy & Physiology I & II (often with stringent timing requirements)
    • Microbiology (usually with a lab component)
    • General Chemistry (or sometimes specifically “Chemistry for Health Sciences”)
    • Nutrition (sometimes categorized as a science, sometimes as an elective)

    Pro Tip: When choosing between Anatomy and Physiology I & II versus a combined A&P course, check your target schools’ requirements carefully. Many competitive BSN programs specifically prefer or require the two-semester sequence for deeper learning.

    Mathematics Requirements

    Math might not be what you envisioned for nursing, but dosage calculations and understanding research statistics are essential nurse competencies. Most programs require:

    • Statistics (Introductory Statistics is most common)
    • College Algebra (or sometimes a higher-level math course)

    Some programs may accept other quantitative reasoning courses, but Statistics is almost universally required.

    Social Sciences and Communication category includes:**

    • General Psychology
    • Developmental Psychology or Lifespan Psychology
    • Sociology
    • English Composition (usually two semesters)
    • Public Speaking or Interpersonal Communication

    ADN vs. BSN vs. Accelerated BSN: How Do Prerequisites Differ?

    The type of nursing program you’re targeting significantly impacts your prerequisite planning. Let’s compare the common requirements across different pathways to help you make informed decisions about your academic journey.

    Associate Degree in Nursing (ADN)

    ADN programs typically have the most streamlined prerequisite requirements. They focus on the essential sciences and minimal general education requirements to get you into the workforce quickly. However, don’t mistake “fewer” for “easier”—ADN programs often have competitive admissions processes that weigh prerequisite grades heavily.

    Bachelor of Science in Nursing (BSN)

    Traditional BSN programs usually require the most extensive list of prerequisites, particularly at competitive universities. These programs often include additional science courses, more social science requirements, and higher standards for overall academic preparation. The advantage? A BSN provides more comprehensive education and increasingly represents the standard for hospital employment.

    Accelerated BSN Programs

    Designed for students who already hold a bachelor’s degree in another field, accelerated BSN programs offer the fastest path to RN licensure—typically 12-18 months. However, they often have the most rigid and specific prerequisite requirements, with less flexibility in course substitutions and stricter recency policies.

    Program TypeTypical Number of PrerequisitesAverage Completion TimeGPA ConsiderationUnique Requirements
    ADN7-9 courses1-1.5 yearsPrereq GPA crucialMinimal general education
    BSN10-14 courses1.5-2.5 yearsBoth overall & prereq GPAOften requires additional sciences
    Accelerated BSN8-12 specific courses1-2 yearsExtremely competitiveStrict course recency rules
    Winner/Best ForADN: Fastest entry to workforce
    BSN: Comprehensive education
    Accelerated BSN: Second-degree speed

    Key Takeaway: Research your target programs early—preferably 12-18 months before you plan to apply. Each program’s specific prerequisites should drive your academic planning, not a generic list.

    Crucial Factors Beyond Just Passing: GPA and Timing

    Completing your prerequisites is just half the battle. How you complete them matters immensely to admissions committees. We’ve seen countless students complete all the right courses but sabotage their applications by overlooking these critical factors.

    The Prerequisite GPA

    Most nursing programs calculate a separate prerequisite GPA that often carries more weight than your cumulative GPA. This focused calculation tells admissions committees how you’ll perform in science-heavy coursework. Competitive BSN programs typically look for prerequisite GPAs of 3.5 or higher, while ADN programs may accept 3.0-3.2.

    Imagine this scenario: Two applicants have identical cumulative GPAs of 3.4. However, Applicant A earned a 3.8 prerequisite GPA with A’s in all sciences, while Applicant B scraped by with C’s in A&P but A’s in easier electives. Who do you think gets the admission offer?

    Course Recency

    Here’s something that catches many applicants off guard: most nursing schools have “recency requirements” for science courses. This means your A&P from seven years ago might not count! Most programs require science and math prerequisites to be completed within 5-7 years of application, with some highly competitive programs requiring recency within just 3-5 years.

    Pro Tip: If you completed science courses outside the recency window, consider taking a “refresher” course or combining a review with a new related science (like taking pathophysiology if your A&P is expired). Some schools accept a combination of old courses plus newer science credits.

    Your Strategic Action Plan: How to Complete Prerequisites Efficiently

    Now that you understand what’s needed, let’s create your roadmap. Strategic planning can save you thousands of dollars and months—or even years—of your time.

    Step 1: Research First, Enroll Second

    Before registering for a single course, compile a spreadsheet of your top 5-8 target nursing programs. List their specific prerequisites, noting variations between schools. Create columns for required courses, minimum grades, recency requirements, and any special notes (like “must include lab component”).

    Step 2: Choose Your Cost-Effective Path

    Community colleges are the secret weapon for savvy nursing students. You can complete most prerequisites at a fraction of university tuition costs, then transfer those credits. Just be absolutely certain the courses will transfer to your target programs!

    Step 3: Plan Your Sequence Strategically

    Some courses must be taken in order. You can’t take Microbiology before Biology, and many programs require Chemistry before A&P. Plan your sequence to avoid wasting semesters waiting on prerequisites.

    Consider this example: Sarah planned her courses poorly and ended up taking only two courses her final semester before applications were due, pushing her application timeline back a full year. Don’t be Sarah—plan your sequence from the end date backward!

    Step 4: Excel in Your Courses

    Remember that prerequisite GPA? Every grade matters. Approach these courses with the same seriousness you’ll apply to your actual nursing courses. Form study groups, utilize campus tutoring resources, and connect with your professors during office hours.

    Common Mistake: Assuming that just “passing” is good enough. In competitive nursing admissions, a C in a prerequisite science course is often the kiss of death for your application. Many programs won’t even consider applicants with more than one C in prerequisite coursework.

    Common Mistakes to Avoid When Planning Your Prereqs

    Let’s be honest—nursing school preparation is complex enough without making avoidable errors. Here are the most costly mistakes students make and how to sidestep them:

    Taking Non-Transferable Courses

    You’ve just spent $1,500 and an entire semester on “Introduction to Chemistry” only to discover your dream BSN program only accepts “General Chemistry I.” This nightmare scenario happens when students don’t verify course transferability before enrolling.

    Solution: Always check thearticulation agreements or transfer guides between your current school and target nursing programs before registering. Most universities list this information on their nursing program admissions websites.

    Ignoring Application Deadlines

    Nursing programs often have application deadlines that are 6-12 months before the program start date. Many students mistakenly plan to complete their final prerequisites in the application semester, only to discover they’ve missed the deadline by months.

    Solution: Work backward from your intended program start date, then subtract the application deadline, then subtract time for transcript processing. This gives you your true completion deadline for all prerequisites.

    Underestimating the Time Commitment

    Science prerequisites with labs are demanding. Working full-time while taking A&P I, Microbiology, and Statistics is a recipe for burnout and poor grades. Spacing out your difficult courses allows for deeper learning and better performance.

    Pro Tip: Consider taking your most challenging science courses during summer sessions when you can focus on fewer classes at once. Many students earn their best science grades in accelerated summer formats when they’re not juggling multiple difficult courses simultaneously.

    Frequently Asked Questions

    We’ve gathered the most common questions students have about prerequisites for nursing to help clarify the confusing details.

    Can I CLEP out of a prerequisite?

    Generally no. Most nursing programs require actual coursework with grades for science prerequisites, not just demonstrated knowledge through exams. Some programs may accept CLEP credits for psychology or sociology, but rarely for sciences.

    Do online prerequisites count?

    Yes, increasingly so—especially after COVID-19 shifted education online. However, science courses with laboratories must include a lab component, either through virtual simulations or in-person lab requirements. Always verify with your target programs first.

    How long do nursing prerequisites take?

    For a full-time student without prior college credits, most complete prerequisites in 1.5-2 years. Part-time students typically need 2-3 years. Accelerated options exist but require intense time commitments.

    What if my prerequisite GPA isn’t high enough?

    If your prerequisite GPA is below 3.0, consider retaking your lowest-graded science courses. Most programs will consider the higher grade in their calculations, and some allow grade replacement policies. You might also consider ADN programs as a stepping stone to RN-to-BSN completion later.

    Can I take prerequisites while applying to nursing school?

    Yes, many programs allow you to have prerequisites “in progress” during application season. However, all requirements must typically be completed before the program begins. Some programs give preference to applicants who have already completed all prerequisites.

    Conclusion: Your Roadmap to Nursing School Is Clear

    Mastering your nursing school prerequisites is entirely achievable with strategic planning and dedicated effort. Focus on excelling in science courses, understanding your target programs’ specific requirements, and maintaining a strong prerequisite GPA. The path may seem lengthy, but each course completed brings you one step closer to your nursing career. Remember, thousands of students successfully navigate this journey each year—and with this roadmap, you can too.
