ATI Score to NCLEX Pass Probability: The Complete Conversion Chart (2026)
If you just got your ATI score back and want to know what it predicts for the NCLEX, this is the article. We cover the ATI Comprehensive Predictor probability chart, what ATI Proctored exam scores mean, the caveats everyone glosses over, and what to actually do with your results.
ATI Comprehensive Predictor: NCLEX Pass Probability Chart
The ATI Comprehensive Predictor is the most widely used ATI assessment for predicting NCLEX readiness. ATI publishes their own probability data based on their research. Here's what the data shows:
NCLEX-RN Pass Probability by ATI Comprehensive Predictor Score
| ATI Comp Predictor Score | Probability of Passing NCLEX-RN (First Attempt) |
|---|---|
| 95–100% | ~99% |
| 90–94% | ~97–98% |
| 85–89% | ~95–97% |
| 80–84% | ~92–94% |
| 75–79% | ~88–91% |
| 70–74% | ~82–87% |
| 65–69% | ~74–80% |
| 60–64% | ~64–72% |
| 55–59% | ~52–62% |
| Below 55% | ~40–50% |
ATI's own benchmarks: ATI defines a score of 68.7% or above as indicating high probability of passing NCLEX-RN. Most nursing programs use a 65–70% threshold as the line between "likely ready" and "needs additional prep."
ATI Proctored Exam Scores by Subject: What the Levels Mean
ATI uses a Level system (1, 2, 3) for Proctored subject exams. Here's what each level predicts for NCLEX content mastery:
ATI Proctored Exam Level Benchmarks
| ATI Level | Score Range (approx.) | What It Means |
|---|---|---|
| Level 3 | 90th percentile+ | Exceeds expected NCLEX readiness in this content area |
| Level 2 | 66th–89th percentile | Meets expected NCLEX readiness — this is the target |
| Level 1 | 33rd–65th percentile | Below expected readiness — remediation recommended |
| Below Level 1 | Below 33rd percentile | Significant content gap — requires focused intervention |
The target most programs set: Level 2 or above on all Proctored exams. Programs that require Level 2 or above for graduation/progression are using ATI data appropriately as a readiness gate.
Subject-Specific Benchmarks That Matter Most for NCLEX
Some ATI subject exams are stronger predictors of NCLEX performance than others. Based on the content weighting of the NCLEX:
| ATI Subject Exam | NCLEX Content Weight | Why It Matters |
|---|---|---|
| ATI Pharmacology | 12–18% of NCLEX | Pharm is the most consistently tested content area |
| ATI Med-Surg | ~30–35% of NCLEX | Physiological Integrity is the largest category |
| ATI Fundamentals | ~20% of NCLEX | Safety, infection control, basic care |
| ATI Mental Health | 6–12% of NCLEX | Smaller weight but psychosocial content appears throughout |
| ATI Maternal-Newborn | 9–15% of NCLEX | Frequently tested, has specific high-yield content |
| ATI Pediatrics | 9–15% of NCLEX | Less tested than med-surg but still meaningful |
| ATI Leadership | ~17–23% of NCLEX | Management of Care/delegation category |
ATI Comprehensive Predictor: What It Is and How to Interpret It
The ATI Comprehensive Predictor is a 180-question exam covering all NCLEX content areas. It's the most predictive single ATI assessment for NCLEX outcomes. Here's how to interpret your result:
Your Individual Probability Score
When you get your Comprehensive Predictor results, ATI gives you an individual probability score (e.g., "75% probability of passing NCLEX-RN"). This is calculated based on your performance relative to the normed population of nursing students.
What the score does not tell you:
- Whether you'll pass — it's a probability, not a guarantee
- Whether you're ready for NGN-specific formats (the Comprehensive Predictor has a more limited NGN question bank than the actual 2026 NCLEX)
- What specific content areas to fix before your exam date
What it does tell you:
- A general readiness signal relative to your peers
- Which content areas in your detailed report are below the passing standard
- Whether your current trajectory needs a significant intervention
The Content Area Breakdown Is More Valuable Than the Overall Score
Most students focus on their overall probability score. The smarter move is to look at the content area breakdown — specifically any areas marked "Below the Passing Standard." These map directly to NCLEX client needs categories.
The 2026 Test Plan Factor: Why Your ATI Score Might Understate Your Readiness Gap
Here's a nuance most articles don't address: the April 1, 2026 NCLEX test plan update shifts the content weighting and further emphasizes clinical judgment and NGN formats. ATI's Comprehensive Predictor is calibrated to predict NCLEX performance — but there's a lag between when NCSBN updates the test plan and when predictive assessments are fully recalibrated.
What this means practically:
- If your Comprehensive Predictor showed 70–75% probability, you're in a borderline zone — but the actual 2026 exam may be more NGN-intensive than the predictor accounts for
- Strong performance on traditional multiple-choice in ATI does not fully predict performance on bow-tie and matrix questions
- Students with borderline ATI scores should treat NGN format practice as a specific additional preparation requirement, not something covered by content review
The students most at risk for a disconnect between ATI probability and NCLEX performance are those who score well on ATI Proctored content exams but haven't specifically practiced clinical judgment question formats.
What to Do With Your ATI Score
If You Scored 80%+ Probability
You're in good shape. Your risk of failing is low, but it's not zero. Focus your remaining prep on:
- Any content areas marked "Below Passing Standard" in your detailed report
- NGN format fluency — even well-prepared students can stumble on bow-tie and matrix formats if they haven't practiced them specifically
- Test-taking stamina (full-length simulations)
If You Scored 65–79% Probability
This is the "needs focused work" zone. Students in this range pass all the time — with targeted preparation. What to do:
- Pull up your detailed ATI report and list every content area marked "Below Passing Standard" or "Near Passing Standard"
- Map those to NCLEX client needs categories (see the table above)
- Dedicate the majority of your remaining prep time to those specific areas
- Specifically add NGN format practice — bow-tie, matrix, and cloze questions — which aren't well represented in ATI content review
The students in this range who fail the NCLEX typically failed because they reviewed the same broad content they already reviewed rather than targeting their specific CPR-identified gaps. Be ruthless about prioritization.
If You Scored Below 65% Probability
You need to extend your prep timeline. Below 65% means the data says you're more likely to fail than pass on the current trajectory.
What this does not mean: that you can't pass. It means your current preparation level is insufficient. Students who score in the 55–65% range and give themselves 6–8 additional weeks of focused, targeted preparation — and change their study method, not just the hours — frequently pass.
What to do:
- Do not schedule your exam until you've significantly moved your practice test scores
- Run full ATI practice Comprehensive Predictors every 2–3 weeks to track progress
- Prioritize clinical judgment practice over content review — if you're already at 60%, you have most of the content. What you're likely missing is the application layer.
FAQs
What ATI score is needed to pass NCLEX?
ATI doesn't have a single "required" score for NCLEX passage — it uses probability estimates. Most programs target a Comprehensive Predictor score of 65–70% or above (corresponding to roughly 75–82% probability of passing NCLEX-RN). Scoring above 68.7% puts you in ATI's "high probability" zone.
How accurate is ATI at predicting NCLEX results?
ATI's Comprehensive Predictor is among the most validated NCLEX predictors available. The correlation between ATI probability scores and actual NCLEX outcomes is strong at the population level. Individual predictions are less certain — especially for borderline cases (65–75% probability range) and for students whose ATI preparation differs significantly from their NCLEX preparation.
Does ATI use the same question formats as the 2026 NCLEX?
ATI has been incorporating NGN-style questions including bow-tie, matrix, and cloze formats. Their coverage of these formats is expanding but is not yet equivalent to the actual 2026 NCLEX's NGN emphasis. This is why a student's ATI score can overestimate NCLEX readiness when NGN format fluency is the limiting factor.
Can I retake the ATI Comprehensive Predictor?
Most nursing programs allow or require students to retake the Comprehensive Predictor if they score below the program threshold. Retaking it 4–6 weeks after a low score with targeted preparation is useful — the score movement tells you whether your remediation is working.
What's the difference between ATI probability and Kaplan's NCLEX predictor?
Both measure NCLEX readiness but use different methodologies. ATI's probability is derived from their own research population. Kaplan's NCLEX Readiness test uses its own norming. Neither is a perfect predictor; both are better than nothing. The content area breakdowns are generally more actionable than the overall scores.
