TEAS vs HESI A2: Which Nursing Entrance Exam Should You Take?
Compare the TEAS 7 and HESI A2 by purpose, subjects, timing, scoring, difficulty, and preparation so you know what your nursing program requires.
Quick answer: TEAS vs HESI A2
The TEAS 7 and HESI A2 are nursing and health-program admission assessments, but they are not interchangeable at every school. ATI gives the TEAS a fixed four-section structure, while schools can select the HESI A2 subject exams they want applicants to complete. Start by checking each program's admissions page for the required exam, sections, scores, attempt rules, and deadline.
If a program accepts either exam, compare the tested subjects with your strengths. The TEAS 7 combines Reading, Mathematics, Science, and English and Language Usage in one exam. The HESI A2 can assess Mathematics, Reading Comprehension, Vocabulary and General Knowledge, Grammar, Biology, Chemistry, and Anatomy and Physiology, depending on the modules selected by the school.
TEAS vs HESI A2 comparison
| Feature | ATI TEAS 7 | HESI A2 |
|---|---|---|
| Exam purpose | Measures entry-level academic readiness for health science programs. | Helps health-profession programs evaluate applicants' existing academic knowledge. |
| Subjects | Four required sections: Reading, Mathematics, Science, and English and Language Usage. | Modular subject exams. A school chooses which subjects applicants must take, so requirements vary. |
| Questions and timing | 170 questions in 209 minutes across four timed sections. Of these, 150 are scored and 20 are unscored pretest items. | Each current academic module contains 30 or 55 items. All seven common modules total 310 items and 285 recommended minutes, but applicants take only the modules assigned by their school. |
| Scoring | Reports a total score and content-area scores. ATI confirms that each school establishes the score it requires. | Reports performance by assigned subject area and a composite based on completed exams. Elsevier describes 75–79% as satisfactory preparation and 80–89% as very good; schools set their own admission cutoffs. |
| Difficulty | Can feel harder if integrated science or the pace of four required sections is a weakness. | Can feel harder if a school assigns several separate science and language modules. |
| Best prep path | Diagnose all four required areas, review weak topics, then rehearse section timing. | Confirm the assigned modules first, then focus study time on those subjects and their weakest topics. |
There is no universal winner in a TEAS vs HESI difficulty comparison. The harder test is usually the one that places more weight on your weaker subjects or gives you less comfortable pacing. Admission standards also belong to the nursing program, not to a universal national passing score.
What is the main difference between the TEAS and HESI A2?
The clearest difference is fixed structure versus school-selected modules.
Every TEAS 7 candidate takes the same four broad sections. ATI's current content outline lists 170 total questions and 209 minutes of testing time. Of those questions, 150 are scored and 20 are unscored pretest items. Your preparation must therefore cover all four sections even if one is already a strength.
The HESI A2 is more configurable. Elsevier's current admission-assessment guide covers Mathematics, Reading Comprehension, Vocabulary and General Knowledge, Grammar, Biology, Chemistry, and Anatomy and Physiology. The four 55-item language and math modules plus three 30-item science modules total 310 items. Elsevier's recommended times total 285 minutes, or about 4 hours 45 minutes, when all seven are combined. A school may assign only the subjects relevant to its admission requirements, so another applicant's HESI question count and testing time may not match yours.
You may see descriptions of eight sections, 326 questions, or about five hours. Those figures can reflect an older HESI version or the addition of non-academic assessments. They should not be presented as the fixed format for every current applicant.
Before building a plan, write down the exact requirements published by your target program. Do not assume that another nursing school's exam or score requirement applies to yours.
Which exam should you take?
Use this decision order:
- Follow the program requirement. If your nursing program names one exam, prepare for that exam.
- Check every target school. Applicants to several programs may encounter different accepted exams or score rules.
- Confirm the HESI modules. If HESI A2 is required, ask which subject exams are included.
- Confirm minimum and competitive scores. A published minimum may not describe the score profile of admitted students.
- Check attempt and deadline rules. Retake limits and score-report deadlines can change your preparation schedule.
If a school genuinely accepts either assessment, try representative questions from both formats before choosing. Compare accuracy, pacing, and unfamiliar material rather than relying on claims that one exam is always easier.
How the subjects compare
Both exams assess foundational skills used in nursing education, but they organize that material differently.
Reading and language
The TEAS separates Reading from English and Language Usage. HESI A2 can separate Reading Comprehension, Vocabulary and General Knowledge, and Grammar into individual subject exams. HESI candidates should prepare for the language modules assigned by their school rather than treating them as one generic English section.
Mathematics
Both exams include foundational mathematics. Start with a timed baseline, identify whether errors come from concepts or pacing, and use the relevant TEAS practice tests or HESI A2 practice tests to target weak areas.
Science
The TEAS Science section combines human anatomy and physiology, biology, chemistry, and scientific reasoning within one required section. HESI A2 offers science areas as separate modules, and a program decides which ones applicants take. HESI candidates should verify their assigned modules before spending equal time on every science subject.
Best preparation path for each exam
Preparing for the TEAS 7
- Take a baseline test across all four sections.
- Review the lowest-scoring topics with the TEAS study-guide hub.
- Use subject practice to correct knowledge gaps.
- Add timed section practice once accuracy improves.
- Recheck all four areas before test day because every section is required.
Preparing for the HESI A2
- Get the required subject list from your nursing program.
- Take a baseline set for those assigned areas.
- Review weak concepts with the HESI A2 study-guide hub.
- Use subject questions to practice applying each concept.
- Rehearse the complete assigned combination under your school's stated timing rules.
Preparation tools that help for either exam
The exam-specific plan matters, but several study tools remain useful for both assessments.
- Start with the official content outline. Match every study topic to the current ATI blueprint or the HESI modules assigned by your program. This prevents broad review from consuming time that should go to tested material.
- Use a structured study guide. Work through weak concepts in a deliberate order instead of collecting disconnected notes and videos.
- Take practice questions and timed tests. Practice reveals whether a missed answer came from knowledge, interpretation, or pacing. Review the rationale before moving to another set.
- Use flashcards for recall-heavy material. The TEAS flashcard hub and HESI A2 flashcard hub are most useful for terminology, formulas, grammar rules, and science facts that need repeated retrieval.
- Add explanation-based support when needed. Video walkthroughs, tutors, or worked examples can help when repeatedly reading the same material does not resolve a concept gap.
The key is to connect each resource to evidence from your own results. A study guide supplies structure, practice exposes the gap, and focused review helps correct it before the next timed attempt.
Frequently asked questions
Is the TEAS harder than the HESI A2?
Not for everyone. Difficulty depends on the HESI modules your school assigns, your academic strengths, and the pacing rules. Compare the actual requirements rather than relying on a universal difficulty label.
Do nursing schools accept both the TEAS and HESI A2?
Some programs may accept more than one admission assessment, while others specify one. Check the current admissions requirements for every program before registering.
Are the TEAS and HESI A2 passing scores the same?
No. Schools establish their own admission standards and may evaluate total, composite, or subject-level performance differently. Use the requirement published by your program rather than a national passing-score claim.
Does every HESI A2 test contain the same subjects?
No. The HESI A2 is modular, so the assigned subject combination can vary by school. Confirm your required modules directly with the program or testing office.
Can I use the same study plan for both exams?
You can reuse a baseline-review-practice-retest workflow, but the content plan should match the exam. TEAS preparation must cover its four required sections; HESI preparation should follow the exact modules assigned by the school.
Final takeaway
The most important TEAS vs HESI A2 difference is not which exam is easier. It is that the TEAS has a fixed four-section blueprint while the HESI A2 can be configured by the school. Confirm the program requirement first, identify the subjects that affect your application, and then use targeted study guides and practice questions to close measurable gaps.
