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 essential groundwork that ensure you have the necessary knowledge base to handle the academic intensity of a BSN program, ADN program, or ABSN program program.
Below, we’ll walk through the must-have nursing school prerequisites, show you how to navigate program-specific rules, and highlight student-friendly routes available for every type of student—from recent high school graduates to adult learners.
What Are Nursing Prerequisites and Why Do They Matter?
Nursing prerequisites are designated college classes needed before entry that must be completed before a student can apply to or enroll in a nursing program. These courses serve three core functions:
- Lay the Groundwork: They provide the necessary science and general-education base 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 top consideration for admission committees when determining if you can handle the intensity 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 highly competitive GPA in your science prerequisites (typically 3.0 or higher) is essential for gaining acceptance into many programs.

Must-Have Nursing Prerequisites You’ll Need
While specific requirements can differ by school and location, there is a core set of prerequisite courses for nursing school that almost every program demands. These are often the hardest prerequisites, but they are key to your success in the field.
The Big Three Science Prereqs
These three disciplines form the foundation of medical understanding and patient care:
- Anatomy & Physiology (A&P I & 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 essential to understanding health and disease.
- Microbio: 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.
General Education Nursing Prerequisites
In addition to the hard sciences, nursing programs require general education courses to ensure you possess strong problem-solving, communication, and social awareness skills:
- Math: Usually includes Algebra at the college level and/or Intro 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 General Psychology (especially Lifespan Development) and Sociology are crucial for understanding human behavior, mental health, and the social dynamics that affect patient wellness.
- Human Nutrition: A dedicated course on nutrition is increasingly common, covering dietetics and the role of food in health and disease management.

Key Logistics for Nursing Prereqs
Completing the courses is only part of the journey. Successful applicants must also navigate administrative and logistical requirements effectively.

Accreditation Basics for Nursing Programs
Accreditation is paramount. You must ensure that the nursing program you plan to apply to is recognized by a national organization, such as the CCNE accreditation or the ACEN accreditation.
Why This Is Important:
- It verifies the program meets national benchmarks for quality.
- It ensures you are eligible to sit for the NCLEX-RN.
- It is often required for military benefits, federal financial aid, and most employers.
Making the Most of Transfer Credits
If you have existing college credits, knowing how to transfer them can save you significant time and tuition. Programs have specific transfer credit policies. It's vital to:

- Verify Equivalence: Contact the nursing school's admissions office to confirm that your specific course at your current college is accepted as equivalent to their prerequisite.
- Check Recency: 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.
- Review Pass/Fail Policies: 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 Requirements 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.
Flexible Ways to Complete Nursing Prerequisites
The journey to nursing school isn't a single set path. Many resources are available to help busy adults meet their nursing prerequisites without interrupting their lives.
Taking Nursing Prereqs Online
The rise of online prereqs offers unparalleled flexibility. Taking courses like Statistics, Psychology, and even some science courses virtually allows students to:
- Learn on Their Schedule: Many accredited platforms offer self-paced learning, which is ideal for working adults or single parents.
- Lower Tuition: Online courses from community colleges or external educational providers often have a lower tuition cost.
- Learn Anywhere: Overcoming geographical limitations to access required courses.
Important: Always verify with your target nursing school that they accept online prerequisites, particularly for laboratory components.
Guidance for Career Changers and Veterans
- ABSN Programs: 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 prereqs, but your previous degree fulfills the general education requirements.
- Veterans: 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.
Budgeting for Your Prerequisites
The financial planning of your education should cover more than just nursing school tuition. Taking prerequisites can represent a significant financial investment.
Plan for:
- Tuition Per Credit: Community colleges usually offer the most affordable path for prerequisites.
- Materials and Lab Fees: Science courses often have mandatory lab fees and expensive textbooks.
- Funding: 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 prereq courses is the first and most crucial step toward your goal of becoming a nurse. It requires a clear plan, a strong focus on your science GPA, and a commitment to understanding the unique requirements of your chosen nursing programs.
Take the time now to:
- Map Out Your Courses: Compare the prerequisites of at least three nursing schools you are interested in and create a master list of courses you need.
- Confirm Transfer Credits: Contact the admissions offices of your target schools before enrolling in any course.
- Treat Prereqs Seriously: Treat these courses as an audition for nursing school. High grades will give you access to the best programs.
Start your planning today, and you will be well on your way to a successful application and a fulfilling career in professional nursing.
