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 professional 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 hurdles to jump; they are the crucial academic building blocks that ensure you have the necessary knowledge base to handle the challenging workload of a Bachelor of Science in Nursing (BSN), Associate Degree in Nursing (ADN), or accelerated nursing track program.
In this guide, you’ll learn the core nursing prerequisites you need, show you how to navigate complex requirements, and highlight flexible options 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 required college courses you must complete first that must be completed before a student can apply to or enroll in a nursing program. These courses serve three core functions:
- Build Foundational Knowledge: They provide the necessary science and general-education base to understand advanced concepts in pharmacology, pathophysiology, and patient care.
- Show Admission Committees You Can Succeed: Your performance in these courses, particularly your Prerequisite GPA, is often the top consideration for admission committees when determining if you can handle the academic load of nursing school.
- Standardize Entry: They ensure all students entering a program have met a minimum standard of academic preparation, regardless of their previous major or educational background.
A strong GPA in your science prerequisites (typically at least a 3.0) is critical for gaining acceptance into many programs.

Essential Science and Math Prerequisites for Nursing School
While specific requirements can differ by school and location, there is a core set of pre-nursing classes that almost every program demands. These are often the most challenging courses, but they are crucial to your success in the field.
The Core Science Requirements
These three disciplines form the cornerstone of medical understanding and patient care:
- Anatomy and Physiology: 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.
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 problem-solving, communication, and social awareness skills:
- Mathematics: Usually includes Algebra at the college level and/or Intro Statistics. Statistics is particularly important for interpreting medical research and evidence-based practice.
- English/Communication: Comp I and 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 Developmental Psychology/Lifespan Development) and Social Science 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.

Why Accreditation Matters
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 Accreditation Commission for Education in Nursing (ACEN).
Why Accreditation Matters:
- It verifies the program meets rigorous national quality standards.
- It ensures you are eligible to sit for the RN licensure exam.
- 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:

- Confirm Course Equivalency: 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 5–10 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.
Licensing Rules by State
It's crucial to understand that Board of Nursing rules 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 one-size-fits-all. Many resources are available to help career changers meet their pre-nursing requirements without interrupting their lives.
Taking Nursing Prereqs Online
The rise of virtual nursing prerequisites 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.
Paths for Career Switchers & Veterans
- Accelerated BSN Tracks: If you already hold a bachelor’s degree in a non-nursing field, you are the ideal candidate for an ABSN program. These programs condense the nursing curriculum into roughly a year to a year and a half. 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.
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.
When planning, consider:
- Tuition Per Credit: Community colleges usually offer the most affordable path for prerequisites. Anatomy, and Requirements .
- Books and Lab Costs: 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 prereq courses 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.
