ExploreAbout this exam
The HESI A2 (Health Education Systems, Inc. Admission Assessment) is an entrance exam that many nursing and allied-health programs use to judge whether applicants have the academic foundation for a demanding clinical curriculum. It is most often taken by prospective students applying to pre-licensure nursing programs, and some schools also use it for other health programs or for post-admission remediation. There is no single national rulebook: each program decides which sections it requires, what score it expects, and how often a candidate may sit for the exam, so the same test can carry different weight at different schools.
The assessment samples core academic skills and science content - reading comprehension, vocabulary and general knowledge, grammar, and basic math, alongside biology, chemistry, anatomy and physiology, and physics. Many administrations also include a personal-assessment component that is not treated as an academic subject.
Preparation works best as a structured review of fundamentals. Confirm with your target program which sections are required and what score it wants, then practice each required subject with untimed review first and timed sets later. Treat your program's own handbook as the final word on every requirement. This page is independent study material and is not affiliated with or endorsed by the exam's publisher.
What you'll study
About HESI A2 preparation
What is the HESI A2 actually used for?
It is an admissions tool. Nursing and health-science programs use the results, usually alongside GPA and prerequisites, to decide who is ready for the academic load of a clinical program. Some schools also use it to place admitted students or to identify who needs remediation before starting coursework.
How many questions are on it and how long does it take?
There is no single published figure you can rely on, because the number of sections a candidate takes and the length of each section are set by the administering program. Ask your target school's testing office for the exact section list and time allowance before you build a study schedule.
What score do I need to pass?
Passing standards are set by each program, not by a national authority, so there is no universal cut score. Some schools publish a minimum composite, others set minimums per section. Get the requirement in writing from the program you are applying to, since an unofficial rumor is a poor planning tool.
Can I retake the exam if I do poorly?
Retake rules vary by institution. Programs commonly set a waiting period between attempts and cap the number of attempts allowed, and some require remediation or an advisor meeting first. Confirm the policy with your school before you register, and do not assume a second attempt is automatic.
Which sections should I study first?
Start with the sections your program actually requires and scores. Within those, front-load the subjects where your diagnostic practice scores are weakest, then protect steady review time for math and reading, which reward consistent practice. Leave the sections your school ignores until the required ones feel solid.
Is the exam harder than other nursing entrance tests?
Difficulty is largely a function of your background, not of the exam's reputation. The science sections reward genuine coursework in biology, chemistry, and anatomy and physiology; the math and reading sections reward practice and careful reading. Candidates who review fundamentals systematically tend to find it manageable.
Are calculators or reference sheets allowed?
Test-day rules are set by the testing center and the administering program, and they can differ between sites. Ask your school's testing coordinator directly about calculators, scratch paper, and any formula reference, and plan to do arithmetic confidently by hand in case none is permitted.
How far ahead should I schedule the test?
Schedule once you know your program's deadline and required sections, and leave yourself enough review time to work through each required subject more than once. Seats at testing centers can fill, so registering early protects your preferred date. Build in a buffer in case you need to reschedule.
What are the most common preparation mistakes?
Studying every subject equally instead of the ones your program requires, memorizing isolated facts without practicing applied questions, skipping timed practice until the last week, and ignoring the program's own requirements. Another frequent error is relying on secondhand claims about scoring instead of the school's published policy.
