Applicants sometimes ask whether the HESI A2 or the ATI TEAS is the easier nursing entrance exam. Usually the first question should be different: which examination will the nursing program accept? Schools choose the admission assessments and the required components. A result from an otherwise well-prepared candidate has little application value if the intended program does not accept that test. The HESI Admission Assessment and ATI TEAS 7 measure overlapping academic skills, but their structure, scoring, timing, and registration processes differ in consequential ways.
The TEAS is a standardized four-section ATI exam with 170 questions in 209 minutes. HESI A2, from Elsevier, is a suite of academic subject assessments from which a school chooses its required combination. Some programs add a separate Critical Thinking component or other institutional conditions. Rather than choose by perceived difficulty, first obtain the program’s current written admission instructions and use those to determine the test you must study.
The school determines which assessment counts
Confirm the exact nursing credential, start term, campus, and applicant track before selecting an entrance exam. A prelicensure BSN transfer route, ADN, LVN-to-ADN bridge, and vocational nursing pathway can apply different assessment policies, even when operated in the same region. Ask whether TEAS 7 or HESI A2 is required, whether an equivalent score from another examination is acceptable, and whether a result from remote or external testing will count.
For HESI, get the complete list of required sections and any minimum score for each one. For ATI TEAS, confirm the overall threshold, any subject-specific minimum, the number of attempts considered, and the required transcript delivery. A school might also ask for remedial steps after a low score. These details are not peripheral: they decide which materials are relevant and whether a retake strategy is even available.
ATI TEAS 7 has a fixed four-section blueprint
ATI TEAS 7 tests Reading, Mathematics, Science, and English and Language Usage. Candidates encounter 170 questions, including 20 unscored development items, with 209 minutes of allocated section testing time. Reading has 45 questions and 55 minutes; Mathematics has 38 and 57; Science has 50 and 60; English and Language Usage has 37 and 37. Sections occur in that order, and spare time from one does not move to the next. Candidates should prepare for multiple-select, ordered-response, fill-in-the-blank and hotspot items alongside ordinary multiple choice.
This standardized structure means the TEAS 7 exam structure applies across test settings, while the school decides the score it will accept. TEAS questions require interpretation of texts, mathematical reasoning, anatomy and physiology, biology, chemistry, scientific reasoning, grammar, and effective language usage. ATI provides an official content outline, current Version 7 guide, and practice forms aligned to the same domains. The exam is an admission assessment rather than a direct nursing licensure test.
HESI A2 uses school-selected subject tests
HESI Admission Assessment (A2) commonly offers Mathematics, Reading Comprehension, Vocabulary and General Knowledge, Grammar, Anatomy and Physiology, Biology, and Chemistry. Some institutional descriptions also list Physics or personal-assessment components. Elsevier’s current sixth-edition A2 preparation guide covers its academic areas, but a prospective student should not assume that every school will administer every subject or count every score. One institution may emphasize Math, Reading, Grammar, Vocabulary, and Anatomy and Physiology; another can add Biology, Chemistry, or Critical Thinking.
University of Texas Rio Grande Valley explains explicitly that schools select their own required HESI components and cut scores. Applicants preparing the HESI A2 science components should identify exactly which are requested by the receiving institution. Studying a Physics section that your school does not administer wastes preparation time; neglecting a required A&P or Reading section can jeopardize eligibility. Read the institution’s current procedure for booking, test setting, identification and any required single-sitting rules.
What the scores mean and how schools interpret them
ATI reports an adjusted individual total on a percent scale and content-area results in an official performance profile. The 150 scored items contribute to results, while 20 unscored items do not. ATI uses equating to account for differences among forms, so a reported TEAS total is not simply correct answers divided by 170. The score profile includes national comparisons and topics needing review. The school—not ATI’s national average—determines the admission threshold or points awarded.
HESI A2 provides percentages for the required academic subject exams and may calculate an institution-specific composite from the components administered. Some programs apply a minimum to every required subject; others use a cumulative threshold. HESI results should not be converted to an invented TEAS equivalent or compared against TEAS preparedness categories. Likewise, a school’s HESI 75% requirement does not mean that TEAS 75% meets its standard. Always quote the assessment and scoring policy together.
Timing and test format require separate preparation
TEAS is separately timed by four fixed content sections. In HESI A2, duration depends on the subject combination and the scheduling arrangement authorized by the school. Elsevier’s faculty scoring guide provides recommended times for particular HESI sections; those recommended durations are not a universal six-hour exam for every applicant. Confirm both the sections and session rules on the testing confirmation instead of copying generic timing charts.
For either examination, the legitimate format matters. ATI offers in-person and remote TEAS variants through ATI, institutions, or PSI, each with technical and ID requirements. HESI can be scheduled through an institution or an approved proctoring/test-center arrangement selected by the school. A remotely delivered test is not automatically accepted by every program. Registration should follow the receiving school’s instructions, and candidates need to allow time for score reporting before application deadlines.
How to build an efficient study plan for either exam
Begin with the required domains. For TEAS 7, use official section objectives to diagnose reading-inference errors, ratios and proportions, scientific reasoning, anatomy and physiology, and English editing. Practice alternate formats and separate section time limits. ATI’s Practice Forms A and B contain 150 questions each, while the proctored assessment has 170; the difference should not be mistaken for a missing portion of the real test. The practice forms can inform study priorities but do not guarantee a reported admission score.
For HESI A2, choose the exact required academic modules and the latest Elsevier study guide sections for them. An applicant required to complete Reading, Math, Grammar, Vocabulary, and A&P should not devote most of the schedule to an optional subject merely because a general study book includes it. Track which objective caused a mistake: a ratio setup, a body-system function, a main-idea inference, or a grammar rule. Revisit each weakness with a short set of problems and a clear explanation.
If you are applying to two nursing schools and they require different exams, do not assume that retaking one assessment or submitting one transcript will satisfy both. Work backward from each school’s application window and testing policy, then compare whether two registrations are realistic without sacrificing time needed to prepare adequately. Ask whether the program accepts a result taken at another institution, which HESI subject combination it considers complete, and whether TEAS attempts appear on the recipient’s score transcript. Also confirm that the school has not changed its entrance testing policy for the next cohort. A candidate who is eligible under last year’s HESI composite rule may still need an extra subject exam if the new application notice adds it. The practical consequence of comparing exams is therefore a documented admissions plan, not just a preference for one study book over another.
Retakes, transcripts and score validity differ by school
ATI does not set a universal waiting period between TEAS retakes, but a school may limit the number or timing of attempts. Schools also choose how old a TEAS score may be, which attempts they consider, and whether external scores or particular proctors are permitted. HESI policies are similarly set by institutions, sometimes including the number of attempts or whether components must be completed together. A school’s admissions page is therefore a more reliable authority than a forum post about a different program.
Confirm how the official score is delivered, whether additional transcripts cost extra, and whether a result can reach the admissions office before its deadline. For TEAS at ATI and some PSI testing formats, applicants may need to send a transcript credit through their ATI account; institution-proctored modes can forward results differently. HESI results follow the ordering institution’s process. Do not substitute unofficial screenshots for an official report unless the school expressly permits them.
Choose a program pathway, not an exam based on convenience
If your preferred program requires only TEAS, prepare for that exam even if you are already familiar with HESI materials. If it requires HESI A2, request the precise component list before buying resources. If a program explicitly accepts both, compare scheduling availability, accepted scores, testing conditions and the content areas you know well, and ask the school how it compares results for selection. A single individual’s claim that one exam is easier cannot reliably predict which test will suit a different applicant.
Both examinations assess academic readiness for education in health professions, but neither establishes licensure eligibility by itself. The right preparation plan is founded on the receiving school’s admission requirements, an accurate issuer blueprint, and enough practice to recognize and correct actual weaknesses. Making that determination first prevents a common and costly mistake: preparing diligently for an assessment that the intended program does not accept.
