Why Nursing School Prerequisites Matter
Completing nursing school prerequisite courses gives you the foundational knowledge for success in nursing school and eventually the demanding world of nursing and healthcare.
Prerequisites demonstrate to program leaders that you are prepared as a student and are capable of taking on the rigorous demands of nursing school.
Introductory physical and social science courses provide nursing students with essential skills. These often include subjects like statistics or English composition, which some nursing programs may not offer directly.
The program you’re interested in can often help direct you to schools where you can complete your prerequisite courses. Community colleges are a common setting for prerequisite courses for nursing school and many other career pathways.
Nursing School Prerequisites: The Basics
In addition to completing specific courses, students usually need to meet other prerequisites.
As for GPA requirements, applicants typically need C-level grades or better for general education and science courses. Associate degree in nursing (ADN) programs often admit students with an overall high school GPA between 2.5 and 2.75, while bachelor of science in nursing (BSN) degrees require at least a 3.0 GPA. More selective undergraduate programs may require GPAs of 3.25 or higher.
Nursing school programs have become increasingly competitive, so students should aim for grades in the B range and higher GPAs, both in general and in prerequisite coursework.
Nursing schools often ask for a personal essay describing educational and career goals. You can make essays stand out from the competition by explaining why you want to attend this program, how you became interested in nursing, and what personal or volunteer experiences helped expand your interest in healthcare.
Although many schools no longer require standardized tests, students who score well on the SAT or ACT may submit these results to bolster their academic record. Some nursing schools require entrance exams, such as the National League for Nursing Pre-Admission Exam or the Nursing Entrance Test. Your intended school can advise you on whether these exams are required for the program.
