A Complete Guide to Nursing Prerequisites and Beginning Your Nursing Career
Choosing nursing as a career can be deeply fulfilling, 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 prerequisite courses for nursing school. These foundational courses are not just hurdles to jump; they are the crucial academic building blocks that ensure you have the necessary knowledge base to handle the academic intensity of a bachelor’s-level nursing program, ADN program, or accelerated nursing track program.
Below, we’ll walk through the must-have nursing school prerequisites, show you how to navigate complex requirements, and highlight student-friendly routes available for every type of student—from students fresh out of high school to career changers.
Understanding Nursing Prerequisites (and Why They’re Important)
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 key goals:
- Create a Strong Academic Foundation: They provide the necessary science and general-education base to understand advanced concepts in nursing theory and hands-on patient care.
- Prove You’re Ready for Nursing School: Your performance in these courses, particularly your science/prerequisite GPA, is often the top consideration for admission committees when determining if you can handle the pace of nursing school.
- Set a Common Baseline: They ensure all students entering a program have met a baseline level 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 essential for gaining acceptance into many programs.

Must-Have Nursing Prerequisites You’ll Need
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 key to your success in the field.
The Core Science Trio (The Non-Negotiables)
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 the top science prerequisite. You'll learn the structure (anatomy) and function (physiology) of the human body, which is essential 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 essential for grasping infection control and infectious diseases.
- Chemistry: 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.
Other Common Prereqs: Math, English, and Gen Ed
In addition to the hard sciences, nursing programs require general education courses to ensure you possess strong critical thinking, communication, and social awareness skills:
- Math: Usually includes Algebra and/or Statistical Methods. Statistics is particularly important for interpreting medical research and evidence-based practice.
- English/Communication: English Composition (I & II) is required to hone the clear, professional communication skills necessary for documenting patient charts and interacting with healthcare teams.
- Social & Behavioral Sciences: Courses like Intro Psych (especially Lifespan Development) and Intro 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.
Handling the Details: Accreditation, Transfers, and Picking a Program
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 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 You Should Care:
- It verifies the program meets rigorous national quality standards.
- 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.
Making the Most of Transfer Credits
If you have existing college credits, knowing how to transfer them can save you significant time and money. 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.
- Confirm the Time Window: Many science prerequisites (A&P, Microbiology) have a time limit and may need to have been completed within the last 5 to 10 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.
State-Specific Nursing Regulations
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.

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:
- Control Their Timeline: 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.
- Avoid Location Limits: 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
- Accelerated Nursing Programs (ABSN): If you already hold a bachelor’s degree in a non-nursing field, you are the prime applicant for an ABSN program. These programs condense the nursing curriculum into 12-18 months. You still need to complete the core science and math pre-nursing classes, 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.
Costs to Expect for Nursing Prereqs
The cost breakdown of your education should cover more than just nursing school tuition. Taking prerequisites can represent a significant financial investment.
When planning, consider:
- Per-Credit 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.
- 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 smartest approach to maximize your return on investment (ROI) and minimize debt before the main nursing program even begins.
Conclusion: Your Next Moves Toward Nursing School
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.
Start by doing the following:
- Create Your Course Roadmap: Compare the prerequisites of multiple nursing schools you are interested in and create a master list of courses you need.
