HESI A2 vs ATI TEAS — Nursing School Entrance Tests

Types of Nursing Entrance Exams

Nursing schools across the United States use several different entrance exams to screen applicants. Knowing which one your target program requires — and what it covers — is the first step toward effective preparation.

HESI A2 (Health Education Systems Incorporated Admission Assessment) is among the most widely used. It covers anatomy and physiology, biology, chemistry, math, reading comprehension, vocabulary, and grammar. Programs typically look for a composite score of 75% or higher, though selective schools set the bar at 80–90%.

ATI TEAS (Test of Essential Academic Skills), published by Assessment Technologies Institute, tests reading, math, science, and English and language usage across 170 questions in just under four hours. It is widely adopted by ADN and BSN programs nationwide and produces a composite score expressed as a percentage.

NLN PAX (National League for Nursing Pre-Admission Examination) is used primarily by diploma and associate degree programs. It measures verbal ability, mathematics, and science and reports a composite score alongside individual section scores.

Kaplan Nursing Admission Test is a shorter assessment used by select programs, focusing on math, reading, writing, and science. It is often seen as less rigorous than the HESI or TEAS but still requires deliberate preparation.

What Each Exam Tests

While all four exams evaluate academic readiness for nursing study, they differ in subject emphasis and format. The HESI A2 places heavier weight on science content — especially anatomy, physiology, and biology — making it the most science-intensive of the group. The ATI TEAS balances science and reading equally and is considered the most standardized nationally. The NLN PAX weights verbal ability heavily alongside math and science, which benefits strong readers. The Kaplan test is the shortest and places the greatest emphasis on math and reading comprehension relative to science depth.

Understanding these differences lets you prioritize your study time: heavy science focus for HESI, balanced review for TEAS, verbal skills for PAX, and math fluency for Kaplan.

Scoring Requirements by Exam

Minimum passing scores vary not just by exam but by individual program. Here is a general benchmark for each:

• HESI A2: Most programs require a composite of 75% or higher. Highly competitive BSN programs at major universities often require 80–90%. Some schools set individual section minimums (e.g., 75% in math and 75% in reading) in addition to the composite.
• ATI TEAS: The national average is around 60%. Most ADN programs accept 58–65%; competitive BSN programs expect 70%+. ATI categorizes scores as Basic, Proficient, Advanced, or Exemplary — aim for Proficient (65%) at minimum and Advanced (75%+) for selective schools.
• NLN PAX: Composite scores are reported on a scale with a national mean near 100. Programs typically require scores at the 50th percentile or above. More selective diploma programs may require the 65th–75th percentile.
• Kaplan Nursing: A score of 65% or higher is generally acceptable, though programs vary. Retake policies differ — many schools allow only two or three attempts within a calendar year, with a mandatory wait period between tests.

Always check the specific requirements on your target school's nursing admission page. Do not rely solely on published minimums — competitive cohorts often have average scores significantly above the stated cutoff.

How to Prepare for the Nursing Entrance Exam

Effective preparation follows a predictable pattern regardless of which exam you face.

1. Diagnose your weaknesses early. Take a full-length practice test in timed conditions before you begin studying. Score each section separately. The sections where you score lowest deserve the most study time — do not over-invest in subjects you already know.

2. Build a study schedule at least 6–8 weeks out. Allocate study blocks by section weight. For the HESI, prioritize anatomy and physiology since those sections carry significant weight and require the most memorization. For the TEAS, balance science and reading. For the PAX, strengthen vocabulary and verbal reasoning alongside science fundamentals.

3. Use official prep materials. ATI sells official TEAS practice tests that closely mirror the real exam. Elsevier publishes HESI-specific review books. The NLN sells PAX study guides directly. Official materials are worth the cost because their difficulty and format match the real exam more accurately than third-party books.

4. Practice under timed conditions. Nursing entrance exams are designed so that time pressure is part of the challenge. Students who study content without practicing pacing often run out of time on test day. Simulate real testing conditions — no phone, no breaks outside scheduled ones, strict time limits per section.

5. Focus on science foundations. Anatomy, physiology, biology, and chemistry appear on every major nursing entrance exam. If your science background is weak, invest extra time in understanding cell biology, the body's organ systems, basic chemical reactions, and the metric system. These are not memorization-only topics — you need to understand the concepts well enough to apply them.

6. Review math without a calculator. Many nursing entrance exams restrict or prohibit calculator use. Practice arithmetic, fractions, ratios, percentages, and basic algebra by hand until the operations feel automatic. Dimensional analysis — converting units — is especially important and appears frequently.

7. Use practice questions, not just reading. Passive reading of review books produces limited retention. Work through practice questions after each topic, review every wrong answer in detail, and understand why the correct answer is right rather than just memorizing it.
