- The KNAT has 91 questions across four timed sections totaling 165 minutes - no single overall clock.
- Math is the largest section (28 questions, 31% weight), covering conversions, ratios, percentages, and word problems.
- Passing cutoffs are set by each nursing program, not Kaplan - Jackson College requires 62%, MSU Billings 65%.
- Fees range from $25 to $70 depending on the administering school, so check your program's own testing office.
What the KNAT Actually Tests
The Kaplan Nursing School Admission Test (KNAT) is not a licensing exam and it is not a nursing knowledge test in the way the NCLEX is. It's an admissions screening tool that individual nursing programs use to gauge whether an applicant has the academic foundation to succeed in a demanding coursework schedule. Kaplan develops and delivers the exam content, but your own nursing school administers it - typically at that school's assessment and testing center rather than through a national testing network like Pearson VUE or PSI.
That distinction matters more than most applicants realize. Because each program administers its own KNAT, the fee you pay, the score you need, how many times you can retake it, and how long your score stays valid are all decided locally. If you're comparing notes with a friend at a different school, don't assume your numbers match.

Exam Format and Timing Breakdown
The KNAT is delivered as 91 online multiple-choice questions split into four separately timed sections, for a combined testing time of 165 minutes. Each section has its own clock, and once time expires on a section you move forward - you cannot borrow time from Math to finish Reading, for example. That structure changes how you should pace yourself compared to a single-timer exam.
| Section | Questions | Time Allowed | Domain Weight |
|---|---|---|---|
| Reading | 22 | 45 minutes | 24% |
| Math | 28 | 45 minutes | 31% |
| Writing | 21 | 45 minutes | 23% |
| Science | 20 | 30 minutes | 22% |
Notice that Science has the tightest ratio of time to questions - 30 minutes for 20 questions, or about 1.5 minutes per item, compared to roughly 2 minutes per item in the other three sections. Candidates who haven't reviewed physiology content ahead of time often run out of time here even though the section is shortest overall. Our How Hard Is the KNAT Exam? Complete Difficulty Guide 2026 article goes deeper into which section trips up first-time test takers most often.
An on-screen calculator is built into the testing software for the Math section, and proctors supply scratch paper and pencils. You generally cannot bring your own calculator, so if you're used to a specific model with memory functions, practice with a basic on-screen calculator interface instead so it isn't unfamiliar on test day.
Registration, Fees, and School-by-School Differences
Because your nursing program administers the KNAT directly, registration happens through your school's testing or admissions office rather than a third-party scheduling portal. This also means the fee varies significantly by institution. Documented amounts include $25 at Clayton State University, $50 at the University of Southern Mississippi and Jackson College, and $70 at Delgado Community College. Always confirm the current fee with your specific program rather than assuming a flat national price - for a wider breakdown of what you might budget for prep materials on top of the exam fee itself, see KNAT Certification Cost 2026: Complete Pricing Breakdown.
Attempt limits and retest waiting periods are also program-specific. Common published policies allow one or two attempts per application period, with a minimum 30-day wait required between retests. Score validity windows vary widely too - some programs accept a score for as little as six months, others up to three years. If you're taking the KNAT well ahead of your intended application term, verify your target school's validity window before you schedule, because a strong score that expires before your application deadline is wasted effort. Testing calendars and deadline patterns are covered in KNAT Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Key Takeaway
Before you register, get three numbers in writing from your program: the exact fee, the minimum passing score, and how many attempts you're allowed. These are set locally and are not standardized across schools.
The Four Domains, Section by Section
Passing the KNAT on your first try comes down to matching your prep time to how each section is actually weighted and structured, rather than spreading effort evenly. Here's what each domain demands.
Domain 1: Reading (24%, 22 questions)
Reading measures comprehension and inference from passages, not memorized content. You'll need to identify main ideas, distinguish supporting details from conclusions, and interpret author intent within a tight 45-minute window.
- Practice skimming for structure before reading for detail
- Watch for questions that ask you to infer rather than recall
- Budget roughly two minutes per question and flag, don't stall
Domain 2: Math (31%, 28 questions)
Math is the largest section on the exam and covers unit conversions, basic and advanced arithmetic operations, ratios, percentages, and word problems presented both as direct equations and as applied real-world scenarios.
- Drill unit conversions until they're automatic - they appear disguised inside word problems
- Practice translating a word problem into an equation before solving
- Use the on-screen calculator during practice so its layout feels familiar
Domain 3: Writing (23%, 21 questions)
Writing tests grammar, sentence structure, punctuation, and clarity of expression rather than composing original essays. Expect error-identification and sentence-correction style items.
- Review common grammar rules: subject-verb agreement, comma usage, parallel structure
- Practice spotting the single error in a sentence quickly rather than rereading the whole passage
Domain 4: Science (22%, 20 questions)
Science is the only section tied to actual health content. It is specifically physiology-focused, covering the cardiovascular, renal, hematological, gastrointestinal, respiratory, immune, sensory, and neurological systems, plus electrolyte balance and homeostasis.
- Build a systems-by-systems review sheet rather than studying anatomy broadly
- Focus on how systems maintain balance (homeostasis) - a recurring theme across questions
- Practice under the tighter 1.5-minute-per-question pace this section demands
For a section-by-section deep dive with sample question styles, our companion piece KNAT Exam Domains 2026: Complete Guide to All 4 Content Areas expands on each of these four areas individually.
A Realistic Study Timeline
You don't need months of preparation for the KNAT, but you do need a plan that respects the section weights above. Math carries the most questions, so it deserves the most repeated review, while Science needs targeted review of specific physiology systems rather than general study.
Math Foundations
- Review unit conversions, ratios, and percentage calculations daily
- Practice translating word problems into equations
- Time yourself at roughly 90 seconds per problem
Reading and Writing
- Practice passage-based inference questions under timed conditions
- Review grammar rules most commonly tested: agreement, punctuation, parallelism
- Take one full-length Reading and one Writing practice section
Science Systems Review
- Build one review sheet per body system listed in the Science domain
- Focus extra time on cardiovascular, renal, and respiratory systems
- Review electrolyte balance and homeostasis concepts specifically
Full Simulations
- Take full-length timed practice tests covering all four sections
- Review every missed question and trace back the underlying concept
- Retest your weakest domain in isolation two to three days before test day
This structure follows a spaced repetition principle: revisit Math concepts briefly during weeks two through four even after week one's focused review, since it's worth the most points overall. If you want a condensed reference to keep handy during this final stretch, our KNAT Cheat Sheet 2026: One-Page Review of Must-Know Facts summarizes the highest-yield facts across all four sections on one page.
Test Day Logistics
Because the KNAT is administered directly by your nursing program's testing center rather than a commercial test network, logistics can differ from what you might expect from other standardized admissions exams. Confirm ahead of time whether you need a printed confirmation, a photo ID, or an appointment made through a specific portal - these details are set by the individual school.
- Scratch paper and pencils are typically provided by the proctor; you generally don't need to bring your own.
- An on-screen calculator is built into the Math section - outside calculators are generally not permitted.
- Results are returned immediately after testing, shown as a percentage score for each section plus a cumulative score, so you'll know where you stand before you leave the testing center.
Because scoring is immediate, it's worth knowing your target cutoff before you sit down. Published institutional benchmarks include 62% for the AAS-N program at Jackson College and 65% at MSU Billings City College, but your own program sets its own threshold.

Common First-Attempt Mistakes
Most repeat test-takers don't fail because the material was impossible - they fail because of avoidable, structural mistakes.
- Treating all four sections as equal weight. Math carries 28 of 91 questions; spending equal study time on all sections shortchanges your biggest scoring opportunity.
- Studying general biology instead of physiology systems. The Science section is narrowly focused on physiology and homeostasis, not broad life-science trivia.
- Ignoring section-specific timing. Since each section has its own separate clock, running out of time on Reading doesn't give you extra time on Writing - and vice versa.
- Not confirming their program's specific cutoff and retake rules before scheduling. A candidate expecting a six-month score validity window at a program that only honors scores for that period can be caught off guard if they test too early.
- Skipping calculator practice. Since outside calculators typically aren't allowed, the on-screen tool needs to feel familiar before test day, not during it.
