✅ Quick Answer: RN program prerequisites typically include Anatomy & Physiology I and II, Microbiology, Chemistry, Psychology, English Composition, and College Math with a minimum 2.5-3.0 GPA.
Essential RN Program Prerequisites
Registered Nurse (RN) programs, whether Associate Degree in Nursing (ADN) or Bachelor of Science in Nursing (BSN), require specific prerequisite courses that provide the scientific and academic foundation for nursing education.
Core science prerequisites for RN programs:
- Anatomy & Physiology I - Study of body structure and function (systems 1)
- Anatomy & Physiology II - Continuation of body systems (systems 2)
- Microbiology - Microorganisms, infection, and immunity
- General Chemistry - Chemical principles for medications and body processes
- General Biology - Foundational life sciences (some programs)
General education prerequisites:
- General Psychology - Human behavior and mental processes
- Developmental Psychology or Lifespan Development - Growth from birth to death
- English Composition I and II - Academic writing and communication
- College Mathematics - Algebra or statistics
- Nutrition - Dietary science and health
- Sociology - Social behavior and cultural diversity (some programs)
Credit Hour Requirements
Most RN programs require 25-35 prerequisite credits, with science courses typically being 3-4 credits each (including labs). The exact number varies between ADN and BSN programs.
ADN vs. BSN Prerequisites
While both pathways lead to RN licensure, prerequisites differ slightly:
ADN (Associate Degree in Nursing) Prerequisites
- Typically 20-25 prerequisite credits
- Focus on essential science courses
- Fewer general education requirements
- Can be completed in 1-2 semesters
- More accessible entry point for career changers
BSN (Bachelor of Science in Nursing) Prerequisites
- Usually 30-40 prerequisite credits
- Same core sciences as ADN
- Additional humanities and social sciences
- May include statistics instead of algebra
- Often require higher GPA (3.0+)
Additional RN Program Requirements
Beyond prerequisite courses, RN programs typically require:
- Minimum GPA - Usually 2.5-3.0 overall, with competitive programs expecting 3.5+
- Entrance exam - TEAS (Test of Essential Academic Skills) or HESI A2
- Background check - Criminal background screening
- Healthcare certifications - CPR certification, some require CNA
- Immunizations - Up-to-date vaccines and health screenings
Timeline for Completing RN Prerequisites
Full-time students: Can complete prerequisites in 1-2 semesters (4-8 months)
Part-time students: Typically finish in 1-2 years while working
Accelerated options: Some students complete prerequisites in 3-4 months through intensive online programs
Tips for Success in RN Prerequisites
Start with Anatomy & Physiology I: This foundational course is required before A&P II and often before microbiology. Don't delay this critical sequence.
Don't rush the sciences: Taking multiple difficult science courses simultaneously can hurt your GPA. Space them strategically.
Build study habits early: The discipline you develop in prerequisites will serve you throughout nursing school.
Connect with advisors: Ensure every course you take will transfer to your target RN program. Requirements vary significantly between schools.
