What Is the HESI A2 Exam? (And Which “HESI” You Actually Need to Take)

The HESI A2 is a computer-based admission test used by nursing and allied health programs. It checks academic skills, not nursing knowledge. Schools choose which sections you take, so your version may not match another applicant’s version. It is also different from the HESI Exit Exam, which nursing students take near graduation.

Have you come across the myth that if you fail one HESI A2 section, you automatically fail the whole test? That is not always true. Many nursing programs review HESI A2 scores by section, and each school sets its own cutoff.

If you are asking what is the Hesi exam is, you are probably trying to understand the HESI A2, the admission test many nursing and allied health programs use before enrollment. The HESI A2 is not a nursing knowledge exam, and it is not the same as the HESI Exit Exam taken near graduation. It is a school-selected academic exam that checks math, reading, vocabulary, grammar, anatomy and physiology, biology, chemistry, and sometimes physics.

The HESI A2 can include up to 8 academic sections plus 2 unscored personal sections, but most schools require only 4 to 6 sections. That difference matters because two students can say they are taking the HESI and still sit for different subject combinations.

This guide explains what the HESI A2 is, who takes it, what is on it, how it compares with TEAS and the HESI Exit Exam, and what to check before booking your test.

Quick Facts About the HESI A2

What Does “HESI” Actually Stand For?

HESI stands for Health Education Systems, Inc. In nursing-school language, the word HESI often gets used as if it means one test. That is where many students get confused. HESI is a testing brand under Elsevier. Nurse.org explains that there are two main HESI exams for nurses: the HESI Admissions A2 and the HESI Exit Exam. The A2 is used before nursing school, while the Exit Exam is used near graduation.

So when someone asks what the Hesi exam is, the first response should be, “Which one?” If you are applying to nursing school, you most likely mean the HESI A2. If you are already in nursing school and close to graduation, you may mean the Exit Exam.

HESI also includes specialty exams used inside nursing programs. These may cover fundamentals, pediatrics, maternity, or medical-surgical nursing. This article focuses on the HESI A2 because it answers the admission question.

What Is the HESI A2 Exam, Specifically?

The HESI A2 is an entrance exam for nursing and allied health applicants. Chamberlain describes the Health Education Systems, Inc. Admission Assessment as an entrance exam that BSN applicants must pass before acceptance into its program. Its page also shows how one school may require only selected academic sections.

If you are wondering what is the hesi a2 exam, think of it as a readiness check. It measures academic skills that nursing programs care about before clinical coursework begins. It does not ask you to make nursing diagnoses, perform patient assessments, or apply NCLEX-style judgment.

The test is modular. One school may require Math, Reading, Vocabulary, Grammar, and Anatomy and Physiology. Another may add Biology or Chemistry.

If you are asking what is a hesi a2 exam, start with your target school’s admissions page. Ask three questions before you pay for anything:

***Which test do they require?

Which HESI A2 sections do they require?

What score do they expect?***

Aisha note: if you are still comparing nursing programs, make a small spreadsheet. List each school, test type, required sections, minimum score, retake rule, and deadline. It prevents booking the wrong exam.

What’s on the HESI A2? (All 10 Sections Explained)

The HESI A2 can test up to 8 academic subjects and 2 personal sections. Schools do not always require every part. That is why what is a hesi test can have different answers depending on the program.

The most common academic mix is Math, Reading, Vocabulary, Grammar, and Anatomy and Physiology. Science-heavy programs may add Biology or Chemistry. Physics is less common.

Chamberlain is a useful school-specific example. Its HESI A2 page lists Reading Comprehension, Vocabulary and General Knowledge, Biology, and Anatomy and Physiology for its required version. It also gives its own timing and attempt rules, which may not match another school. The personal sections are not the same as the academic sections. Learning Style and Personality Profile are usually unscored. Do not treat them like Math or A&P.

Who Takes the HESI A2? (And When)

The HESI A2 is mainly for pre-nursing applicants. That includes many LPN, ADN, BSN, accelerated BSN, and bridge-program applicants. Some allied health programs may also use it for dental hygiene, radiology, respiratory therapy, or similar tracks.

If you are asking what is the hesi exam for nursing, the answer is usually the HESI A2 when you are not yet enrolled. It helps schools compare applicants on academic readiness. It is one part of an admissions file, not the whole file.

Students usually take it before applying or during the application window. Baylor’s nursing school requires applicants to take the HESI A2 and says Math and English composite scores of 80 or better are required to apply. Baylor also requires a 60-day waiting period between tests.

Aisha note: do not rely on a friend’s testing plan. Your school may require different sections, a different score, or a different testing site. Check the admissions page first.

You may not need the HESI A2 if your school uses the TEAS instead. Some programs also use GPA and prerequisites without an entrance exam.

HESI A2 vs HESI Exit Exam: The Difference That Matters

This is the biggest HESI mix-up. The HESI A2 and the HESI Exit Exam belong to the same testing family, but they serve different moments in a nursing student’s path. If you are asking what is the hesi test, do not skip this distinction.

The HESI A2 checks whether you are academically ready to enter a program. It covers school subjects like reading, math, vocabulary, grammar, and science foundations. You should not expect care plans, medication delegation, or priority nursing actions.

The HESI Exit Exam is different. It is used inside nursing programs, often near the end. Nurse.org notes that HESI Exit scores are commonly tied to NCLEX readiness, while the HESI A2 is for admission. If you are a pre-nursing applicant, stay focused on the HESI A2. The Exit Exam is not your test yet.

HESI A2 vs TEAS: Which Test Does Your School Require?

HESI A2 and TEAS are both nursing-school admission exams, but they are not the same test. HESI A2 is published by Elsevier. TEAS is published by ATI Testing. Schools decide which one they accept.

If you are comparing what is a hesi exam with TEAS, start with the structure. The ATI TEAS has 170 total questions and 209 minutes of testing time. It has four sections: Reading, Mathematics, Science, and English and Language Usage.

HESI A2 is more modular. It can include up to 8 academic sections plus unscored personal sections, but schools choose the required parts. That makes the HESI A2 harder to describe with one fixed format.

Some schools accept either exam. Many do not. Do not register for TEAS because your friend took TEAS. Do not register for HESI because a forum post said it was easier.

Use the admissions page as the final answer. If a school accepts both, compare the TEAS and HESI A2 before choosing.

HESI A2 Cost, Time & Logistics (Quick Hits)

HESI A2 logistics are school-specific. That is the part students often miss. The same test family can look different by school, testing center, attempt rule, and required section list.

If you are asking about the A2 exam, include logistics in the answer. You need to know the test itself and the version your school uses.

Here are the quick hits:

• Cost: often around \$35 to \$115, depending on location and school rules.

• Time: a full battery can run about 4 to 5 hours, but many students sit for 2.5 to 3.5 hours.

• Format: computer-based and mostly multiple choice.

• Calculator: usually available on screen for math.

• Retakes: school-specific, often with a waiting period.

• Scores: often available soon after testing, but official reporting rules vary.

• Validity: commonly 1 to 2 years.

Baylor shows how specific policies can get. It allows only one test per semester, has a maximum of three attempts, and requires a 60-day waiting period between tests. Other schools may set different limits.

Before booking, confirm the date, fee, location, required sections, score cutoff, and retake rule.

What Score Do You Need? (Short Answer: It Depends)

There is no national passing score for the HESI A2. Each school sets its own cutoff. That is why the HESI test for nursing should always include the phrase “check your program.”

Some schools use a composite score. Others look at section scores. Some require a minimum in Anatomy and Physiology or English, even if your overall score looks fine.

Baylor gives a clear example. Its nursing page says applicants need minimum scores of 80 or better on both the HESI A2 Math and English Composite portions to be eligible to apply.

Chamberlain gives another example. It says applicants must complete all four required academic exams per attempt, and individual scores are provided for each exam. That proves the myth from the intro is too simple. One school may judge the whole attempt differently from another.

Use this rule: find the cutoff before you study. Then study toward the school’s required sections, not a generic internet target.

What’s Next? (Soft CTA Pivot)

Now you know what the HESI A2 is. The next step depends on where you are in the process.

If you are still choosing schools, compare HESI A2 and TEAS requirements first. If you already know your school requires HESI A2, review the complete HESI A2 prep guide. If you want to see the format before committing to a full course, start with free HESI A2 practice questions.

Testavia fits this stage because it lets you move from explanation to practice. You can use free HESI A2 questions to see Math, Reading, Vocabulary, Grammar, A&P, Biology, and Chemistry in action. Then you can decide whether you need a structured prep plan.

The goal is not to study every possible HESI topic. The goal is to match your school’s version of the exam.

The Bottom Line

The HESI A2 is Elsevier’s pre-admission academic test for nursing and allied health applicants. It can include up to 8 academic sections, but your school chooses what you take. It is not the HESI Exit Exam, and it is not the TEAS.

Start with your school’s admissions page. Confirm the test, sections, score cutoff, cost, and retake rule. Then use Testavia’s HESI A2 practice questions or the full prep guide to move from “what is it?” to “how do I prepare for my version?”
