HESI A2 Practice Test 2026 — ATI Nursing Entrance Exam Prep Guide
HESI A2 practice test 2026: complete guide to the ATI HESI Admission Assessment covering test sections, scoring, subject breakdowns, study tips, and free practice questions.
What Is the HESI A2?
The HESI Admission Assessment Exam — commonly called the HESI A2 — is a standardized academic readiness test developed by ATI (formerly Elsevier Health Sciences). Nursing schools use it to predict which applicants have the foundational academic skills needed to succeed in rigorous nursing curricula.
Unlike the NCLEX (which licenses graduates), the HESI A2 is taken before you start a nursing program. It tests knowledge across science, math, reading, and English language skills. Each school selects which sections it requires, so you should verify the exact requirements with your target program before registering.
The exam is administered at approved testing centers and, at some institutions, in a proctored online format. Because scores are school-specific and not universally transferable, you may need to retake the exam if you apply to multiple programs with different cut-off thresholds.
HESI A2 Key Exam Sections
- Time: 50 minutes
- Topics: Basic math, fractions, decimals, ratios, Roman numerals, dosage calculations
- Focus tip: Dosage and conversion problems are heavily tested — practice milligrams to grams and standard to metric conversions
- Time: 60 minutes
- Topics: Identifying main idea, making inferences, understanding author purpose, vocabulary in context
- Focus tip: Read each passage twice — once for overall meaning, once to locate evidence for each answer choice
- Time: 25 minutes
- Topics: All major body systems, cellular biology, homeostasis, organ structure and function
- Focus tip: A&P is the most challenging section and a common cause of failure — allocate the most study time here
- Time: 45 minutes
- Topics: Subject-verb agreement, correct word usage, punctuation, spelling, sentence structure
- Focus tip: Review commonly confused words (their/there/they're, affect/effect) and comma rules
HESI A2 Scoring at a Glance
Each HESI A2 section is scored on a 0 to 100 scale. Most nursing programs set their minimum acceptance threshold at 75% cumulative, though competitive programs and individual sections may require 80% or higher.
- 75%+ — minimum threshold at most programs
- 80%+ — required per section at many BSN programs
- 90%+ — considered highly competitive; increases admission chances significantly
- Scores are reported per section — a weak section can sink your application even if your average looks acceptable
Always confirm the exact cut-off scores with each school you apply to, as requirements vary widely.
Time Limit, Cost, and Retake Policy
The total time you spend on the HESI A2 depends on which sections your school requires. A full exam covering all eight subjects typically runs 3 to 5 hours, including short breaks between sections. Individual section time limits range from 25 minutes (Anatomy and Physiology) to 60 minutes (Reading Comprehension).
Registration fees typically fall between $40 and $50 per attempt, though the exact cost depends on the testing center and the number of sections included. You pay when you register, so confirm the fee with your school or the testing center in advance.
Most nursing programs enforce a 60-day waiting period between retakes, and many limit the number of attempts to two or three. After exhausting retake allowances at one school, you may be ineligible to reapply to that program for a full academic year. This makes thorough preparation essential — treating your first attempt as a high-stakes test rather than a trial run.
HESI A2 vs. HESI Exit Exam — Key Differences
The HESI brand covers two entirely different exams that are often confused:
- HESI A2 (Admission Assessment) — taken before nursing school; tests academic readiness in math, sciences, and English
- HESI Exit Exam — taken near the end of a nursing program; tests clinical nursing knowledge and is used to predict NCLEX passage rates
If your nursing school mentions the HESI, always clarify which version they mean. Studying NCLEX-style content for your nursing school entrance exam is a common and costly mistake.
Study Strategies by Section
Mathematics: Most students find the math section manageable with focused practice on fractions, ratios, percentages, and metric conversions. Pay extra attention to medication dosage calculations — they appear frequently and follow a predictable format. Use dimensional analysis (the unit-factor method) consistently.
Anatomy and Physiology: This is the section that derails the most applicants. Invest the bulk of your study time here. Learn each body system methodically: structure, function, regulation, and common disorders. Visual learners benefit from labeled diagrams; auditory learners from recorded lectures.
Vocabulary and General Knowledge: Medical terminology questions test Greek and Latin root words. Flashcards — physical or digital — remain the most effective tool. Aim to learn at least 10 new medical terms per study session.
Reading Comprehension: Speed and accuracy both matter. Practice reading dense academic passages and answering questions without rereading the full text. Identify the main idea in the first paragraph and use process of elimination for inference questions.
A well-structured HESI practice test covering all sections is the most efficient way to identify your weak areas before the real exam. Use your practice scores to reallocate study time in the final two weeks before your test date.
