ATI Comprehensive Predictor: what your score actually means
ATI predicts your probability of passing NCLEX with a single number. Here's how reliable it is, the cutoff to aim for, and what to do at each tier.
ATI's Comprehensive Predictor is the exit exam most US BSN programs require. The 'predicted probability of passing the NCLEX' number it spits out is one of the most cited predictors in NCLEX prep, and also one of the most misunderstood.
What the predicted probability means
ATI computes a probability of passing the NCLEX on the next attempt based on your performance on the Comprehensive Predictor. It's a single percentage, e.g., '92% predicted probability of passing.' The percentage reflects ATI's internal validation against actual NCLEX outcomes from prior cohorts.
The cutoffs that matter
92%+ is the standard 'ready' threshold. 88-92% is borderline; more prep recommended. Below 88% means a real risk of failing on first attempt. Many BSN programs require 92%+ to graduate or to be 'released' to test.
How accurate is it?
ATI's validation studies report ~90% pass rates at 92%+. In practice, students at the 92% predictor have ~90-95% real pass rates; students at 88-92% have ~75-85% pass rates; below 88% drops to 60-70%.
What to do at each tier
92%+: Stay sharp. Light maintenance for 2-3 weeks, then test. 88-92%: 4-6 weeks more prep. Focus on the bottom 2 categories from your individual ATI breakdown. Below 88%: 8+ weeks more prep. Rebuild content + add 1,500 more questions before retesting.
Common misuses
Treating the Comprehensive Predictor as a substitute for NCLEX prep. The Predictor is a measure of where you are, not a prep program. A 95% score with no recent question practice is a stale score by test day.
Frequently asked
Is the Comprehensive Predictor harder or easier than the NCLEX?
Similar in feel but slightly different in stem-writing style. ATI questions skew toward content recall; NCLEX skews toward clinical reasoning. The two are not interchangeable but the predictor validity holds.
Can I retake the Comprehensive Predictor?
Yes, most students take it 2-3 times during their program. Each version is a different question set.
