What is the HESI Exam & How to Prepare for It

What Is the HESI Exam?

The HESI exam is an entrance exam required for many nursing and allied health programs. It's a predictor of nursing student success, and many schools use the exam as a part of the admissions criteria for acceptance.

HESI stands for Health Education Systems Incorporated (HESI), which is a US-based company dedicated to developing tests and educational tools for nurses and other healthcare professionals. Although some colleges do not use HESI, it is becoming more common to help students study and pass their licensure exams.

There are two main HESI exams for nurses - the HESI Admissions (A2) and the HESI Exit Exam.

What Is the HESI A2 Exam?

The HESI A2 is a 4-hour exam that some schools give to prospective nursing candidates. Schools may use this test to determine if the applicant qualifies for acceptance into their program. The exam also reveals information about candidates' learning styles, giving schools more information about incoming students.

Some schools customize the HESI for their program by excluding some information and determining their required passing score. If you are taking the HESI exam, contact your nursing program for more exam details.

What Is the HESI Exit Exam?

The HESI Exit Exam is a test given by nursing schools to determine if a student is prepared to pass the NCLEX as they approach graduation. Since graduates must pass the NCLEX to become licensed to practice as a nurse, schools make sure they're prepared for it by administering the HESI Exit Exam. Some schools even use it to determine whether students are eligible for graduation.

Elsevier states that the HESI Exit Exam predicts whether or not a student will pass the NCLEX exam with 98% accuracy.

How to Register for the HESI Exam

You must register to take any HESI exam, receive test results, register for distance exams, and make payments. To do this, you will also need to create a student account.

  1. Step 1: Set up an account at https://evolve.elsevier.com/cs/

  3. Step 3: On the next screen, select “Register for Distance Testing”

Keep in mind that your institution may have other instructions for you regarding making an Elsevier account and registering for a HESI exam. For example, some schools offer the exam online through Proctor U, and others have testing centers that allow you to take it in person.

Bottom Line: Check with your institution to see if it has any additional requirements for registration.

How to Prepare for the HESI Exam

Studying for the HESI exam might seem like a monumental process now, but if you plan ahead and understand the details about the test, you can succeed! You will likely need to study for the HESI exam before getting into a nursing program, and again as you approach graduation. 

Here are some HESI study tips that will help you as you prepare for testing:

  1. Know the Topics: Each program can decide which parts of the HESI exam it will give students. Additionally, each testable subject has a set number of questions and a time limit in which to complete them. Knowing what subjects your university tests will help you focus on areas of importance and practice completing each section in time.

  2. Understand the Scoring System: HESI exams are scored from 100 to 1,000. The higher the score, the better. However, each nursing program may have its own criteria for passing the test. Talk to administrators in your program for more details.

  3. Start with a Practice Test: HESI practice exams give you a feel for what the real test looks like and the types of questions you will see. After your practice exam, you should review the results to identify your strengths and weaknesses and figure out exactly what you should focus on to improve your score.

  4. Follow a Study Schedule: This is not a test that you want to wait until the last minute to study for. Planning out your study time is going to allow you to take your time with the material and not rush at the last minute. It will also leave you less stressed when it is time for you to take your exam.

  5. Develop Your Ideal Study Strategy: Several study methods exist to help you achieve a passing HESI score, including study guides, flashcards, written lessons, videos, and practice questions. Selecting the best method or methods that help you retain knowledge will optimize your study routine.

  6. Take Your Exam Believing You Will Pass: Now that you have fully prepared yourself to pass this exam, be confident about it! Make sure to get a good night's rest and eat a healthy breakfast before you go to your exam. You got this! 

HESI Prep Courses & Practice Tests

HESI offers its own “assignable and gradable” quizzes for self-practice. Self-quizzing throughout your nursing program will best prepare you for answering questions on your licensure exam. It also provides you with details on the subject areas you are underperforming in.

Several other companies also offer HESI prep courses online. Some of the most popular courses include:

  1. Mometrics
  2. Nursing.com*
  3. Pocket Prep
  4. Nursehub

Prep courses are an excellent way to prepare yourself for the NCLEX throughout your program. You can also focus your energy on taking practice tests that align with the coursework you are currently studying.

Prep courses allow you to answer thousands of potential test questions in the same topics you will be tested on during the HESI and NCLEX exams.

What to Do After the HESI Exam

How Long Does it Take to Get Results?

You will receive your HESI score shortly after your exam. Your score and a remediation plan are sent to you within two weeks of completing the exam. 

What Happens if You Fail the HESI Exam? 

The HESI exam is not a traditional pass/fail exam. It gives you a numerical score between 100-1000. The higher the number, the better you performed on the exam. 

Your nursing institution may have a score that you must meet for program acceptance. You need to speak with your administrators to see what the minimum accepted score is. 

Most nursing schools require that students take the HESI before graduation to ensure they are ready to take the NCLEX. Many nursing programs require a score of 850 or higher because that indicates you will most likely pass the NCLEX.

If your score is too low, you will need to retake the exam. Before you do, make sure that you study with HESI prep courses that will help you perform better the next time. 

No matter what nursing program you go to, you will need to study to pass your courses and licensure exams. The HESI exams are a great tool to ensure that you have the necessary knowledge to earn licensure and perform as a nurse. The testing may seem daunting, but you will succeed if you study hard, focus, and use preparation courses.
