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 key foundations that ensure you have the necessary knowledge base to handle the challenging workload 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 flexible options available for every type of student—from students fresh out of high school to those switching professions.
Nursing Prerequisites Explained: What They Are and Why They Count
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:
- Create a Strong Academic Foundation: They provide the necessary scientific and humanities background to understand advanced concepts in pharmacology, pathophysiology, and patient care.
- Demonstrate Academic Readiness: Your performance in these courses, particularly your science/prerequisite GPA, is often the single most important factor 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 baseline level of academic preparation, regardless of their previous major or educational background.
A highly competitive GPA in your science prerequisites (typically 3.0+) is critical 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 nursing prerequisites that almost every program demands. These are often the toughest classes, 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 one of the most important prereqs. You'll learn the structure (anatomy) and function (physiology) of the human body, which is central to understanding health and disease.
- Introductory 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 crucial 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 at the college level and/or Intro Statistics. Statistics is particularly important for interpreting medical research and evidence-based practice.
- English and 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 General Psychology (especially 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.
Handling the Details: Accreditation, Transfers, and Picking a Program
Completing the courses is only half the battle. What Future Nurses Should Know About Prerequisite Classes . 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 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.
How to Transfer Credits Smoothly
If you have existing college credits, knowing how to transfer them can save you significant time and money. Programs have specific credit transfer 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 5–10 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.
State-Specific Nursing Regulations
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 one-size-fits-all. Many resources are available to help career changers meet their required prerequisites without interrupting their lives.
Virtual Prereq Options
The rise of online prereqs 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.
- Save Money: 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.
Paths for Career Switchers & 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 12-18 months. You still need to complete the core science and math prereqs, but your previous degree fulfills the general education requirements.
- Veterans & Military: 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 financial planning of your education should cover more than just nursing school tuition. Taking prerequisites can represent a significant financial investment.
Plan for:
- 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.
- Financial Aid: 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: 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.
