Short answer

ATI is a company that makes nursing school assessments — the TEAS entrance exam, content mastery (proficiency) exams for courses and the Comprehensive Predictor near graduation. The NCLEX is the licensing exam run by NCSBN. Schools use ATI tests to check your progress; the NCLEX decides licensure. Studying NCLEX-style questions with rationales helps with both because they test the same nursing knowledge and clinical judgment.

Key takeaways

  • TEAS is an entrance exam: reading, math, science and English.
  • ATI content mastery exams test individual course subjects and give proficiency levels.
  • The ATI Comprehensive Predictor estimates readiness near graduation.
  • The NCLEX is adaptive and scored pass/fail; ATI exams are fixed-length.
  • The same habits — rationales, prioritization, pharmacology, labs — help on both.

What is ATI testing?

Assessment Technologies Institute (ATI) supplies many nursing programs with exams and review materials. You may meet ATI three times in your nursing journey: before admission (TEAS), during each course (content mastery or proficiency exams) and before graduation (the Comprehensive Predictor). Your school decides which tests count and what score you need.

The main ATI exams

  • TEAS — admissions test covering reading, mathematics, science and English and language usage.
  • Content mastery series — subject exams such as fundamentals, pharmacology, adult medical-surgical, maternal newborn, nursing care of children, mental health, community health and leadership.
  • Comprehensive Predictor — a broad exam near the end of the program that estimates NCLEX readiness.
  • Practice assessments and remediation — focused review tied to your results.

ATI vs NCLEX: key differences

  • Purpose: ATI measures school progress; the NCLEX grants licensure.
  • Format: most ATI exams have a set number of questions; the NCLEX uses computerized adaptive testing, between 85 and 150 questions for RN and PN.
  • Scoring: ATI gives percentages and proficiency levels; the NCLEX is pass/fail.
  • Item types: both include multiple-choice and select-all-that-apply; the NCLEX includes Next Gen case studies, bowtie and matrix items.

How to prepare for ATI and the NCLEX at the same time

The content overlaps heavily. A combined plan:

  • Practice by subject during each course, matching your ATI content mastery topic.
  • Read every rationale — ATI and the NCLEX both reward understanding why.
  • Drill prioritization (ABCs, Maslow, acute vs chronic) and delegation every week.
  • Keep a running list of missed pharmacology and lab values and review it with flashcards.
  • Before the Comprehensive Predictor or the NCLEX, take a full-length timed simulation such as the Naxlex NCLEX Predictor or NCLEX RAT.

Using Naxlex alongside ATI

Naxlex.app is independent of ATI and does not reproduce ATI exams. It gives you original NCLEX-style practice by subject, nursing school course content, TEAS and HESI entrance practice, and exam simulations, so you can study the same nursing topics your ATI tests cover.

Practice questions with rationales

Original NCLEX-style questions. Choose an answer to see the rationale.

  1. 1. A client taking furosemide reports leg cramps. Which lab value should the nurse check?

    Answer and rationale

    Correct: B. Furosemide is a loop diuretic that causes potassium loss. Muscle cramps are a classic sign of hypokalemia.

  2. 2. Which client statement shows understanding of warfarin teaching?

    Answer and rationale

    Correct: B. Consistent vitamin K intake keeps INR stable. Aspirin adds bleeding risk, and INR checks are essential.

Frequently asked questions

Is ATI the same as the NCLEX?

No. ATI makes school assessments; NCSBN runs the NCLEX licensing exam.

Does a good ATI score help on the NCLEX?

The knowledge overlaps, so strong preparation for one supports the other.

Does Naxlex have TEAS practice?

Yes, Naxlex includes TEAS and HESI A2 entrance practice.
