Why Nursing School Prerequisites Matter
Completing nursing school prerequisites lays the groundwork for your success in both nursing school and a future healthcare career. These courses show program leaders that you’re academically prepared and capable of handling the challenges of a rigorous nursing curriculum.
Introductory courses in physical and social sciences — such as biology, psychology, sociology, and statistics — build essential skills you’ll rely on throughout your training. Programs may also require courses in the humanities or language arts, such as English composition or communication, demonstrating a well-rounded education, especially when the program does not offer these classes.
If you’re unsure where to begin, the nursing program you’re interested in can guide you to schools that offer the prerequisites you need. Many students choose to take these courses at community colleges, which provide flexible, affordable pathways into nursing and other healthcare professions.
Nursing School Prerequisites: A Full Overview
In addition to required courses, nursing schools often consider several other admissions criteria. GPA is a key factor — most ADN programs look for a high school GPA between 2.5 and 2.75, while BSN programs typically require at least a 3.0. More selective schools may expect a GPA of 3.25 or higher. To stay competitive, students should aim for strong grades in both general education and science prerequisites.
Many programs also require a personal statement outlining your career goals and interest in nursing. Sharing relevant volunteer work or healthcare experiences can help your essay stand out. While some schools no longer require standardized tests, high SAT or ACT scores can strengthen your application. Certain programs may still require nursing school entrance exams.
Once you understand the general admissions requirements, it’s time to take a closer look at the coursework most nursing programs require before you apply.
Nursing School Prerequisites: Common Coursework Requirements
Whether you’re pursuing an associate or bachelor’s degree, most accredited nursing programs require a combination of science and general education courses designed to prepare you for safe, effective patient care. The following list is a compilation from several top schools.

How to Complete Nursing School Prerequisite Courses
Prospective nursing students have several options for completing their prerequisites. Many enroll in required courses before applying to an ADN or BSN program, often through a community college, university, or accredited online provider. Some high school students may also begin early through dual-enrollment opportunities.
These courses provide the academic foundation needed for nursing school. Students who already hold a non-nursing bachelor’s degree can complete prerequisites before entering an accelerated BSN program. In some cases, schools allow students to take outstanding prerequisites alongside their nursing courses after admission.
Most nursing programs require that prerequisites be completed within five years of applying. To help offset the cost, students can explore and apply for various financial aid options. Start by submitting the Free Application for Federal Student Aid (FAFSA), which is required for several funding options.
Frequently Asked Questions About Nursing School Prerequisites
The most important prerequisites for nursing school typically include anatomy, physiology, microbiology, chemistry, biology, and statistics.
