A Complete Guide to Nursing Prerequisites and Beginning Your Nursing Career
Embarking on a career in nursing is a profoundly rewarding decision, but the path to becoming a licensed Registered Nurse (RN) begins long before you step foot in a clinical setting. It starts with successfully completing your nursing prerequisites. These foundational courses are not just boxes to check; they are the key foundations that ensure you have the necessary knowledge base to handle the rigorous demands of a BSN program, associate nursing program, or ABSN program program.
This guide will break down the essential prerequisite courses for nursing school, show you how to navigate program-specific rules, and highlight student-friendly routes available for every type of student—from students fresh out of high school to those switching professions.
What Are Nursing Prerequisites and Why Do They Matter?
Nursing prerequisites are a specific set of required college-level courses that must be completed before a student can apply to or enroll in a nursing program. These courses serve three main purposes:
- Lay the Groundwork: They provide the necessary academic foundation to understand advanced concepts in medications, disease processes, and clinical care.
- Prove You’re Ready for Nursing School: Your performance in these courses, particularly your pre-req GPA, is often the primary factor for admission committees when determining if you can handle the pace of nursing school.
- Standardize Entry: They ensure all students entering a program have met a shared threshold of academic preparation, regardless of their previous major or educational background.
A solid GPA in your science prerequisites (typically at least a 3.0) is often required for gaining acceptance into many programs.

Essential Science and Math Prerequisites for Nursing School
While specific requirements can vary between institutions and states, there is a core set of prerequisite courses for nursing school that almost every program demands. These are often the most challenging courses, but they are vital to your success in the field.
The Core Science Requirements
These three disciplines form the cornerstone of medical understanding and patient care:
- A&P I and II: Often split into two semesters, A&P is arguably the most critical prerequisite. You'll learn the structure (anatomy) and function (physiology) of the human body, which is foundational to understanding health and disease.
- Microbiology: This course covers microorganisms (bacteria, viruses, fungi, and parasites), their relationship to the human body, and the mechanisms of infection and immunity. It’s key for grasping infection control and infectious diseases.
- Chem: Typically, general chemistry is required, sometimes followed by an organic chemistry or biochemistry component. This knowledge is crucial for understanding pharmacology, fluid and electrolyte balance, and metabolic processes.
Math, English, and General Education Requirements
In addition to the hard sciences, nursing programs require general education courses to ensure you possess strong analytical, communication, and social awareness skills:
- Quantitative Skills: Usually includes College Algebra and/or Statistics. Statistics is particularly important for interpreting medical research and evidence-based practice.
- Writing & Communication: Freshman Composition is required to hone the clear, professional communication skills necessary for documenting patient charts and interacting with healthcare teams.
- Social & Behavioral Sciences: Courses like Psychology (especially Developmental Psychology/Lifespan Development) and Social Science are crucial for understanding human behavior, mental health, and the social dynamics that affect patient wellness.
- Nutrition: A dedicated course on nutrition is increasingly common, covering dietetics and the role of food in health and disease management.
Navigating the Logistics: Accreditation, Transfers, and Program Choice
Completing the courses is only one piece of the puzzle. Successful applicants must also navigate administrative and logistical requirements effectively.

Accreditation Basics for Nursing Programs
Accreditation is absolutely essential. You must ensure that the nursing program you plan to apply to is recognized by a national organization, such as the CCNE or the Accreditation Commission for Education in Nursing (ACEN).
Why This Is Important:
- It verifies the program meets national benchmarks for quality.
- It ensures you are eligible to sit for the National Council Licensure Examination for RNs.
- It is often required for financial aid and employer recognition.
Maximizing Your Credit Transfer Guide
If you have existing college credits, knowing how to transfer them can save you significant cost and effort. Programs have specific credit transfer policies. It's vital to:

- Check Matching Courses: Contact the nursing school's admissions office to confirm that your specific course at your current college is accepted as equivalent to their prerequisite.
- Make Sure Credits Aren’t Too Old: Many science prerequisites (A&P, Microbiology) have a time limit and may need to have been completed within the last five to ten years to be accepted.
- Watch for Pass/Fail Rules: Most programs require a letter grade (usually a "C" or better) for all prerequisites, especially the core sciences. Pass/Fail grades are often not accepted.
Know Your State Requirements
It's crucial to understand that state regulations affect your licensing. While prerequisites are set by the school, nursing regulations and licensing standards (such as background checks, clinical hour requirements, and NCLEX registration) are governed by your state’s Board of Nursing. Always consult the official board for the state where you plan to practice to ensure your chosen program meets all necessary criteria.
Options That Fit Your Life
The journey to nursing school isn't a single set path. Many resources are available to help career changers meet their required prerequisites without interrupting their lives.
Online Nursing Prerequisites
The rise of virtual nursing prerequisites offers unparalleled flexibility. Taking courses like Statistics, Psychology, and even some science courses virtually allows students to:
- Set Their Own Pace: Many accredited platforms offer self-paced learning, which is ideal for working adults or single parents.
- Reduce Costs: Online courses from community colleges or external educational providers often have a lower tuition cost.
- Learn Anywhere: Overcoming geographical limitations to access required courses.
Note: Always verify with your target nursing school that they accept online prerequisites, particularly for laboratory components.
Guidance for Career Changers and Veterans
- Accelerated BSN Tracks: If you already hold a bachelor’s degree in a non-nursing field, you are the perfect fit for an ABSN program. These programs condense the nursing curriculum into about 12 to 18 months. You still need to complete the core science and math nursing prerequisites, but your previous degree fulfills the general education requirements.
- Military Students: Military medical experience and training (such as medic or corpsman training) can often be leveraged for credit or to waive certain prerequisites. Explore specialized programs that recognize and integrate your military background.
Financial Planning: Understanding the Cost of Prerequisites
The cost breakdown of your education should cover more than just nursing school tuition. Taking prerequisites can represent a significant financial investment.
Be sure to factor in:
A Guide to Anatomy Requirements for Nursing Majors .- Credit-Based Tuition: Community colleges usually offer the most affordable path for prerequisites.
- Materials and Lab Fees: Science courses often have mandatory lab fees and expensive textbooks.
- Aid Options: Prerequisites taken at a college or university may be eligible for federal financial aid (FAFSA), especially if you are seeking a degree or certificate.
Taking your prerequisites strategically and utilizing affordable, accredited online options is the best way to maximize your return on investment (ROI) and minimize debt before the main nursing program even begins.
Conclusion: Taking the Next Step in Your Nursing Journey
Completing your pre-nursing requirements is the first and most crucial step toward your goal of becoming a nurse. It requires careful planning, a strong focus on your science GPA, and a commitment to understanding the unique requirements of your chosen nursing programs.
Your next steps should be:
- Map Out Your Courses: Compare the prerequisites of multiple nursing schools you are interested in and create a master list of courses you need.
- Check Transfer Policies: Contact the admissions offices of your target schools before enrolling in any course.
