Quick answer: The main NCLEX-RN prep programs each include an adaptive readiness check, but they measure it differently. UWorld includes 1 to 6 self-assessments of 100 questions, depending on plan, which it says give a statistically validated readiness prediction. Archer Review lists 30+ readiness assessments and CAT exams and reports your pass probability from low to very high. Kaplan’s CAT + Qbank includes 3 full-length CATs. NCLEX Key’s adaptive CAT simulator runs 85 to 150 questions and reports whether you are above or below the passing standard. None of these is an official NCLEX prediction, so look for consistent results across several tests. Details are from each program’s website on September 29, 2026.

A readiness test answers the question every NCLEX candidate has before booking: am I ready? The NCLEX-RN is itself adaptive, so the most useful practice tests adapt too and tell you where you stand against the passing standard. Here is how the main options compare.

| Your nursing program | Many schools give a standardized exit exam, such as ATI’s RN Comprehensive Predictor or the HESI Exit Exam | Varies by exam; ask your program how it uses the score | Through your school |
NCLEX.com’s free Candidate Tutorial and Sample Pack are also worth doing, but they are for learning the exam software and item types rather than for measuring readiness.

- Included on every plan, from $59 for 30 days, alongside 3,500+ questions and all 6 NGN item types
- Part of our Pass Guarantee for first-time candidates, which asks for one full CAT above the passing standard and at least 500 questions, among its conditions
How to get the most from a readiness test
- Take one early as a baseline, so you know which client-needs categories to focus on.
- Take it in one sitting, under exam-like conditions, so the result reflects test-day stamina too.
- Use questions you have not seen. Retaking the same items inflates your score.
- Look for a pattern, not one score. Archer Review, for example, recommends that first-time users get four consecutive “High” or “Very High” readiness assessments before the NCLEX.
- Retest after focused study. If you land near or below the standard, work on your weakest categories and read every rationale before trying again.

Frequently Asked Questions
Which NCLEX readiness test is the most accurate?
Each program measures readiness its own way, and none is an official NCLEX prediction. UWorld says its self-assessments give a statistically validated prediction, and Archer Review reports pass probability from low to very high. The most useful signal is a consistent result across several tests taken on questions you have not seen.
What does “above the passing standard” mean?
The NCLEX-RN decides pass or fail by comparing your ability to a fixed passing standard, not to other test-takers. A practice CAT that reports “above the passing standard” is estimating that your performance was above that line on its questions.
How many readiness tests should I take before the NCLEX?
Take one early as a baseline and several more as your exam date gets closer. Archer Review recommends four consecutive “High” or “Very High” readiness assessments; NCLEX Key’s Pass Guarantee asks for at least one full CAT above the passing standard.
Is there a free NCLEX readiness test?
NCLEX.com’s Candidate Tutorial and Sample Pack are free, but they teach the software and item types rather than score readiness. Adaptive readiness tests are usually part of paid plans; NCLEX Key’s CAT simulator is included on every plan from $59.
Does NCLEX Key have a readiness test?
Yes. Every paid plan includes an adaptive CAT simulator that ends between 85 and 150 questions and reports whether you are above or below the passing standard, with a tier from Comfortably Above to Below Standard.
