How to interpret NCLEX mock scores
What UWorld SA, Kaplan QT, ATI Comprehensive Predictor, and Archer Readiness actually predict. And what to do with the number.
Each major mock has its own scoring system and its own correlation with the real NCLEX. They are not interchangeable.
UWorld Self-Assessment (SA)
Outputs: 'Very High,' 'High,' 'Borderline,' 'Low,' 'Very Low' probability of passing. Maps closely to real NCLEX outcomes for first-time US BSN candidates. 'High' or 'Very High' on two consecutive SAs is a strong readiness signal.
Kaplan QT5 / QT6
Numeric percentage. 65%+ on QT5 or QT6 is Kaplan's cutoff. Their internal data shows ~90% pass rates above that threshold. Below 60%, more prep needed.
ATI Comprehensive Predictor
Outputs a predicted probability of passing (e.g., '92% predicted probability'). 92%+ is generally considered ready. 88-92% is borderline; below 88% means more prep.
Archer Readiness Assessment
Categorical: 'Very High,' 'High,' 'Borderline,' 'Low.' Archer's case-study and adaptive items track closely to NGN format. 'Very High' on two assessments is a strong signal.
What to do with conflicting scores
If UWorld says 'High' and Kaplan says 62%, the truth is probably in between. The conservative move: assume the lower predictor and study one more week. The aggressive move: trust your trajectory if it's been moving up. There's no perfect answer.
Frequently asked
How many mocks should I take?
For a 4-week runway: 3 total. For 8+ weeks: 4-5. More than that is diminishing returns and shakes confidence on bad-day variance.
Can I trust just one mock?
No. Mock scores have day-to-day variance of 5-10 points. Two consecutive scores in the green is the standard.
