If you’re an aspiring nursing student, completing your prerequisites is typically the first step in the journey. Whether you’re pursuing an Associate Degree in Nursing (ADN), Bachelor of Science in Nursing (BSN), or an accelerated nursing program, prerequisite coursework helps build the academic foundation you’ll need to succeed.
The good news is that many online nursing prerequisite courses can be completed from home, allowing you to work toward your goals on a schedule that fits your life. Find out what you need to know about nursing prerequisites, why they’re required, and how online learning can help you prepare for nursing school.
What Are Nursing Prerequisites? Understanding Nursing School Requirements
Nursing prerequisites are courses that students must complete before they can be admitted into a nursing program. These classes provide foundational knowledge in science, mathematics, communication, and human behavior that nursing students rely on throughout their education and careers.
Though the specific requirements vary by school, most nursing programs require a combination of science and general education courses for a well-rounded education:
- ADN programs often require a smaller set of prerequisite courses focused on foundational sciences and general education.
- BSN programs typically include additional prerequisites and broader general education requirements.
- Accelerated nursing programs may require a completed bachelor’s degree along with specific science prerequisites.
Because admission requirements vary, it’s important to review your intended nursing program’s requirements carefully before enrolling in any courses.
Why Prerequisites Matter
Prerequisite courses serve several important purposes:
- Prepare students for rigorous nursing coursework
- Build essential scientific and healthcare knowledge
- Develop critical thinking and communication skills
- Demonstrate academic readiness to nursing school admissions committees
Strong performance in prerequisite courses can also strengthen your nursing school application and help you feel more confident when beginning advanced nursing studies.
Common Nursing Prerequisites Courses Required by Nursing Programs
While requirements vary by institution, the following courses are among the most commonly required nursing prerequisites.
Anatomy and Physiology
Recommended course: Anatomy and Physiology I
Anatomy and Physiology introduces students to the structure and function of the human body. You’ll learn how body systems work together to maintain health and how disruptions can lead to disease. This course is one of the most frequently required nursing prerequisites because understanding body systems is essential for patient assessment, treatment, and care planning.
Microbiology
Recommended course: Microbiology
Microbiology explores bacteria, viruses, fungi, and other microorganisms. Students learn how infectious diseases spread and how healthcare professionals help prevent and control infections. This knowledge is crucial in nursing practice, particularly in areas such as infection prevention, patient safety, and disease management.
Chemistry
Recommended course: Introduction to Chemistry
Chemistry provides foundational knowledge about matter, chemical reactions, and biological processes. Nursing students use chemistry concepts to understand medications, body functions, and treatment interventions. Many BSN programs require chemistry as part of their admission requirements.
Human Growth and Development
Recommended course: Lifespan Development
Human Growth and Development examines physical, cognitive, emotional, and social development from infancy through older adulthood. Nurses care for patients across all stages of life, so understanding developmental changes helps support effective communication, assessment, and care planning.
Psychology
Recommended course: Introduction to Psychology
Psychology introduces students to human behavior, mental processes, and psychological principles. Nurses frequently interact with patients experiencing emotional, behavioral, and mental health challenges. A foundational understanding of psychology supports compassionate patient care and stronger communication skills.
English Composition
Recommended course: English Composition I
Communication is a vital part of nursing practice. English Composition helps students develop writing, reading, and critical thinking skills needed for academic success and professional documentation. Nurses regularly communicate with patients, families, and healthcare teams, so having strong communication skills is essential to the role.
College Algebra or Statistics
Recommended courses: College Algebra or Introduction to Statistics
Mathematics supports evidence-based nursing practice and clinical decision-making. Students may be required to complete College Algebra, Statistics, or both, depending on program requirements. Statistics is particularly valuable because nurses often work with research findings, healthcare data, and quality improvement initiatives.
Why Nursing Programs Require These Courses
Building Scientific Knowledge
Nursing requires a strong understanding of the human body, disease processes, medications, and treatments. Science-focused prerequisites provide the knowledge needed to understand more advanced nursing concepts. Students who complete anatomy and physiology, microbiology, and chemistry courses often enter nursing programs with a stronger academic foundation.
Strengthening Critical Thinking Skills
Nurses must evaluate information, solve problems, and make informed decisions in fast-paced healthcare environments. Courses in mathematics, sciences, psychology, and composition help students develop the critical thinking and analytical skills necessary for clinical reasoning and evidence-based practice.
Preparing for Nursing Coursework and Clinical Training
Nursing programs move quickly and cover complex material. Prerequisites help students build the academic skills and subject knowledge needed to keep pace with demanding coursework and clinical experiences. Completing prerequisite courses before admission can help ease the transition into nursing school and improve overall preparedness.
