Nursing Entrance Exam: Complete Guide to TEAS, HESI, and Major Nursing Tests

A nursing entrance exam is a standardized test that nursing programs use to screen applicants for academic readiness before admission. Most associate degree nursing (ADN) and bachelor's degree nursing (BSN) programs require you to pass a nursing entrance exam as part of the application process — it's not optional, and your score directly affects whether you get a seat in the program. The specific test required depends on the nursing school: some require the TEAS (Test of Essential Academic Skills), others require the HESI A2, and a smaller number use the NLN PAX or other assessments.

Regardless of which specific nursing entrance exam your target program requires, the underlying content areas are consistent: reading comprehension, English language and grammar, mathematics, and science (biology, chemistry, and anatomy and physiology). The exact proportion of questions in each area and the scoring system differ across exams, but a student who's strong in these core academic areas can perform well on any of the major nursing entrance tests with exam-specific preparation.

Your nursing entrance exam score is typically one of several application factors — alongside GPA, prerequisite course grades, and sometimes interviews or essays. High entrance exam scores compensate for a slightly lower GPA in competitive programs; strong GPA and prerequisite performance can sometimes compensate for a borderline exam score. Understanding how heavily your target program weights the entrance exam score (many programs publish this openly) determines how much preparation investment is warranted and whether retaking after an initial attempt makes strategic sense.

This guide covers the major nursing entrance exams in detail — TEAS, HESI A2, and NLN PAX — explains the content tested in each subject area, provides a structured study plan, and offers section-specific strategies for each content domain. Whether you're starting prep eight weeks out or need to accelerate in three weeks, the material here provides a complete framework for nursing entrance exam preparation.

Most nursing programs that require entrance exams also publish minimum score requirements, which serve as the floor for application eligibility. However, in competitive programs where applications exceed available seats, the effective competitive score is usually well above the published minimum.

A program that lists a TEAS composite minimum of 62% may admit students who averaged 78% in the most recent entering class — the minimum tells you whether you're eligible to apply, not whether you're competitive for admission. Researching your target program's typical admitted-student score profile, often available from admissions staff or program information sessions, gives you a realistic target to prep toward.

Time invested in nursing entrance exam preparation correlates predictably with score outcomes. Students who begin preparation 8–12 weeks before the exam and study 45–60 minutes daily consistently outperform those who cram in the final week or take the exam without specific preparation. The science sections particularly reward distributed learning — cramming A&P content over a weekend produces far less retention than studying one body system per week over several weeks. Building your study schedule backward from your exam date, then backward from that to when you need to register, ensures you don't run out of preparation time.

Science is the most challenging section for most nursing entrance exam applicants — it covers biology fundamentals, chemistry basics, and human anatomy and physiology at a level that's well above what most candidates reviewed in high school. Life science questions test cell biology (organelle functions, cell division, DNA structure and replication), heredity and genetics, and evolution basics. The A&P questions are particularly important: nursing programs need to confirm you have a foundation in how the human body works before teaching you how to care for it professionally.

Chemistry questions on nursing entrance exams focus on atomic structure, chemical bonding, reactions, acids and bases, and solutions. You don't need advanced chemistry — the level is comparable to a solid introductory college chemistry course or a rigorous high school chemistry course. The NEX Basic Chemistry practice tests on this site cover the atomic structure and chemical reaction content that appears consistently across TEAS, HESI, and NLN PAX science sections.

Mathematics on nursing entrance exams covers arithmetic, basic algebra, ratios and proportions, fractions, decimals, and nursing-specific math applications like dosage calculations and unit conversions. The dosage calculation questions are particularly important — they appear on most nursing entrance exams and directly preview the clinical math you'll use throughout nursing school and professional practice. A question like 'How many milliliters of a 250mg/5mL solution provides a 125mg dose?' tests both math fluency and clinical reasoning simultaneously. The NEX Mathematical Calculations practice tests provide targeted dosage calculation practice that directly maps to exam question formats.

Reading comprehension questions test whether you can extract main ideas, identify supporting details, make inferences, and recognize author's purpose from passages similar to what you'd read in nursing textbooks and clinical literature. The passages are typically scientific or medical in tone — passages about clinical conditions, healthcare policy, or biological research are common. Vocabulary questions often appear within or alongside reading sections, testing both general academic vocabulary and medical/healthcare terminology. NEX Grammar practice tests cover the subject-verb agreement, punctuation, and sentence structure questions that appear in the English section of most nursing entrance exams.

English language and grammar questions test practical writing correctness: subject-verb agreement, pronoun agreement, punctuation rules, comma usage, sentence structure, and word choice. These questions appear in the English/Language Usage section of the TEAS and the Grammar section of the HESI A2. Unlike essay-based writing assessments, nursing entrance exam grammar questions are multiple-choice error-identification items — you identify which sentence has an error or which answer choice correctly completes a sentence. Systematic grammar rule review (15–20 core rules) is more efficient than general writing practice for this section.

Critical thinking questions test clinical reasoning ability rather than factual recall. These questions present brief scenarios — a patient report, a clinical situation, a decision point — and ask you to identify the most appropriate nursing response or conclusion. The answer isn't always the most technically correct option in isolation; it's the option that demonstrates sound reasoning under the constraints of the scenario.

Nursing entrance exam critical thinking questions are designed to preview the clinical judgment demands of nursing school, not test medical knowledge. Approaching them with structured reasoning (What information is given? What's the most important problem? What response addresses it directly?) rather than pattern-matching to similar-sounding scenarios reduces errors. The NEX Critical Thinking practice tests build familiarity with the question format that makes scenario-based reasoning feel less unfamiliar on exam day.

The connection between nursing entrance exam content and nursing school success is direct and well-documented. Programs require entrance exams partly as a predictor of which applicants will succeed in their curriculum — and the science, math, and reading demands of the exam genuinely preview what nursing school requires. Students who can demonstrate proficiency in these areas at application time are better positioned for the first-semester workload, which typically involves A&P, pharmacology, nursing fundamentals, and clinical practicums simultaneously. Treating entrance exam prep as foundational nursing education rather than an administrative hurdle produces both better exam scores and better first-semester readiness.

Your nursing entrance exam score needs to meet the minimum required by your target program and ideally land in the competitive range for your program's most recent entering class. Most programs publish their minimum required scores; fewer publish the mean score of admitted students. If a program's minimum TEAS composite is 65% but the mean admitted student scored 78%, your 67% score clears the minimum but leaves you competitively below the average. Knowing this distinction prevents false confidence from simply clearing the minimum when competitive admission requires a higher bar.

Retaking strategy depends on your score relative to your target programs. Most programs allow retakes, but many impose a waiting period (often 30–60 days) between attempts and limit total retake attempts (commonly 2–3 total). If your score is within 5 percentage points of your target program's competitive range, focused targeted prep for the weakest sections and retaking is a reasonable strategy.

If your score is significantly below the competitive range, a more sustained 8–12 week prep cycle before the next attempt will produce more meaningful improvement than a quick retake. NEX Anatomy and Physiology practice tests are among the highest-value prep resources for candidates whose science section score held down their composite.

Program selection strategy interacts with entrance exam performance. If you've taken the TEAS and received a solid but not exceptional score, applying to programs with score requirements aligned to your performance is more efficient than retaking until you hit a higher score threshold.

Many excellent nursing programs — including those offering strong clinical training and high NCLEX pass rates — have TEAS composite requirements in the 65–75% range that aren't the ultra-selective programs with 85%+ cutoffs. Matching your entrance exam performance to programs where you're genuinely competitive maximizes your chance of beginning nursing school this admissions cycle rather than waiting another year to improve a test score.

Preparing for the nursing entrance exam is also preparation for nursing school itself. The science content — particularly A&P — appears directly in nursing school coursework. Students who invest seriously in understanding (not just memorizing for the exam) the cardiovascular system, basic pharmacology principles, and human biology fundamentals during entrance exam prep consistently report feeling more prepared for their first nursing school semester. Treating entrance exam prep as a preview of what nursing education demands, rather than a hurdle to clear and forget, creates a preparation mindset that pays forward into the academic demands ahead.

Group study and peer preparation are underused resources for nursing entrance exam preparation. Finding 2–4 other applicants preparing for the same exam and running weekly study sessions creates structured accountability that individual study plans often lack. Group sessions work best when each participant teaches a section they've prepared — explaining A&P concepts to peers reveals gaps in your own understanding and deepens retention more effectively than re-reading notes. Nursing school application forums (Student Doctor Network, allnurses.com) connect candidates who are preparing simultaneously and often share practice materials, program-specific score data, and prep strategy recommendations.

Time management within the nursing entrance exam is more manageable than on highly time-pressured tests like the PI Cognitive Assessment, but it still requires active attention. The TEAS gives approximately 4 minutes per question on average; the HESI allows similar or slightly more time per section. Most candidates have enough time to complete every question if they don't get stuck on individual problems. The failure mode on nursing entrance exams is usually insufficient preparation, not running out of time — which means thorough content review is the higher priority than speed training.

Test day logistics for nursing entrance exams differ significantly from employer-administered tests. Most TEAS and HESI administrations happen at accredited testing centers (ATI-approved testing sites or proctored university settings) rather than at the nursing school itself. You must register, pay, and schedule in advance.

The ATI TEAS is also available as a proctored online test through ATI's platform. Bring acceptable photo ID and any materials specified by the testing center. Calculator policies vary — the TEAS provides an on-screen calculator for math; HESI may or may not depending on the program and test version. Confirm what's allowed before your test date, not the morning of.

Score validity periods are an important practical consideration. TEAS scores are generally considered valid for 2 years; HESI score validity periods vary by program (often 1–2 years). If you're applying to nursing programs in multiple cycles — this year and potentially next year — check whether scores from this cycle will still be valid for any programs you apply to in a future cycle.

Taking the exam too early (more than 2 years before your target entry date) may require retesting even if your score is strong. Plan your exam timing backward from your application deadline rather than forward from when you happen to be ready.

After receiving your scores, request a detailed score report that breaks down performance by content category. The section-level breakdown reveals which specific topics you missed, which is the most actionable information for understanding where your preparation paid off and where additional study would improve a retake score. Most programs also provide this level of feedback through the testing platform's results portal. Use the detailed breakdown to inform any retake preparation rather than starting from scratch with the same comprehensive study approach that produced your first-attempt score.

Nursing entrance exam scores don't define your nursing career — they're one step in a multi-year academic and professional journey. Students who don't achieve their target score on the first attempt, improve their preparation, and succeed on a retake are following a path taken by many practicing nurses. What matters ultimately is completing an accredited nursing program, passing NCLEX, and developing clinical competence. The entrance exam is a meaningful but bounded obstacle.

Approaching it with thorough preparation, a strategic mindset, and the understanding that an initial score is information rather than a verdict keeps the process in proper perspective. Every nurse who took a nursing entrance exam was once in the same position you're in now — study the content, prepare specifically, and take the test. Preparation, persistence, and a clear plan forward are the only things that separate exam-ready applicants from those who are not.
