Who it's for
RN students nearing the end of the nursing curriculum who are preparing for the ATI Comprehensive Predictor — the capstone exam most programs use to gauge NCLEX-RN readiness. Best used after you've worked through the individual content-mastery topics, as a final cumulative review.

What the ATI Comprehensive Predictor actually covers
Unlike a single-topic content-mastery exam, the Comprehensive Predictor draws items from the whole RN curriculum. Here's what that means for how you study.
Whole-Curriculum Coverage
Instead of testing one content area, the Comprehensive Predictor pulls items from every core RN topic — Fundamentals, Medical-Surgical, Pharmacology, Mental Health, Maternal/Newborn, Pediatrics, Leadership, and Community Health — in a single exam. There's no way to "cram" one domain the night before; broad review across all your prior content-mastery topics matters more here than for any single CMS exam.
Next-Generation NCLEX (NGN) Item Types
Expect case-study exhibits with tabbed vital signs/labs/provider orders, matrix or multiple-response grids, and cloze (dropdown) fill-in-the-blank items, alongside standard single-best-answer questions. These are scored differently than simple multiple choice, so it's worth practicing the format itself, not just the content.
Clinical Judgment & Prioritization
Prioritization questions — who does the nurse see first, what does the nurse do first — appear across every content area on this exam, not just in a Leadership section. The NCSBN Clinical Judgment Measurement Model underlies most NGN items: recognizing cues, analyzing them, prioritizing hypotheses, and generating/evaluating a plan of care.
A Predictive NCLEX-RN Readiness Score
Individual content-mastery exams report a proficiency level (Level 1, 2, or 3) for that one topic. The Comprehensive Predictor instead reports a probability-of-passing-NCLEX-RN band, which is why most programs treat it as a late-curriculum checkpoint rather than a per-course requirement — ask your program which band they require before graduation.
Case-Study Exhibits
A meaningful share of the exam links several questions to one shared case: a set of vital-sign trends, lab values, or provider prescriptions you have to reference across multiple items. Budget more time per case-study cluster than you would for an isolated single-stem question.
Sample Comprehensive Predictor questions with rationales
Rationale: Addressing a quality concern starts with assessing and identifying contributing factors before implementing training, policy changes, or escalation.
Rationale: A grandiose sense of self-importance and need for admiration is the hallmark of narcissistic personality disorder; the other options describe avoidant, obsessive-compulsive, and paranoid personality disorder, respectively.
Rationale: Chest pain with radiation and diaphoresis suggests acute coronary syndrome, a life-threatening emergency requiring immediate evaluation ahead of non-emergent complaints.
Rationale: Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy; INR monitors warfarin, not heparin.
Rationale: Bananas are high in potassium and should be limited in a client with hyperkalemia; the other options are comparatively low in potassium.
ATI Comprehensive Predictor FAQ
How many questions are on the ATI RN Comprehensive Predictor?
ATI's official Comprehensive Predictor is a longer, cumulative exam than a single content-mastery test — the exact question count, time limit, and number of unscored items are set by ATI and your nursing program, so check your course syllabus or ATI Learning System for your cohort's specific format.
What score do I need on the Comprehensive Predictor?
Unlike topic exams, which report a proficiency level (1, 2, or 3), the Comprehensive Predictor reports a probability-of-passing-NCLEX-RN band. Each nursing program sets its own required band for progression or graduation — ask your instructor which one applies to you.
Is this the same test as ATI's official Comprehensive Predictor?
No. This is an independent, original study resource written to cover the same content areas and NGN item styles as ATI's Comprehensive Predictor. It is not affiliated with, endorsed by, or a reproduction of Assessment Technologies Institute's proprietary exam content.
How is the Comprehensive Predictor different from the individual content-mastery (CMS) exams?
Each CMS exam (Fundamentals, Pharmacology, etc.) tests one content area. The Comprehensive Predictor draws items from all of them in one exam, closer in format and difficulty to the real NCLEX-RN, and is typically taken near the end of the program rather than after a single course.
What should I study first if I'm running out of time?
Prioritization and clinical-judgment items pay off the most — they appear across every content area on this exam, not just one section. After that, revisit whichever individual CMS topic you scored lowest on.
What is ATI CMS?
CMS stands for Content Mastery Series — ATI's name for the individual proctored exams like Fundamentals or Pharmacology, as distinct from the cumulative Comprehensive Predictor. Read our full explainer on what ATI CMS means for more detail.
