NAPT Easy Guide: Navy Advanced Programs Test

Didn’t score high enough on the ASVAB for the Navy Nuclear Field (NF) program? You’ll need to pass the NAPT (Navy Advanced Programs Test) to prove your math and science skills.

Here’s the test format, subjects, scoring, and the fastest way to prepare.

What is Navy NAPT?

The NAPT (Navy Advanced Programs Test) is a secondary exam for applicants who didn’t score high enough on the ASVAB to qualify for the Navy Nuclear Field (NF) program. It tests math, physics, and problem-solving skills to ensure candidates can handle the program’s technical demands.

NAPT Test Format

• 80 multiple-choice questions
• Passing score: 55 out of 80
• Time limit: 2 hours (maybe 20 extra minutes)
• Location: MEPS (Military Entrance Processing Station)
• What’s provided: Calculator, scratch paper, pencils
• What you need: State ID (driver’s license) + Social Security card
• Retesting: Allowed once after 90 days if you score 40+, but you must show academic improvement

Subjects Covered on the NAPT

This test is 80% problem-solving, 20% knowledge recall. It’s not just about memorizing formulas—you need to know how to apply them.

• Understand permutations and combinations
• Work with basic statistical analysis and data interpretation

How to Prepare:

• Learn how to calculate probability using fractions and percentages
• Practice questions that involve multiple-step probability problems
• Review statistical measures like mean, median, and mode

Chemistry

• Balance chemical equations
• Understand atomic structure and periodic table trends
• Identify types of chemical reactions (synthesis, decomposition, etc.)

How to Prepare:

• Get comfortable with balancing equations—this shows up often
• Learn to predict reaction products using the periodic table
• Study real-world chemistry applications (e.g., combustion reactions)

How to Use This Information

• Start with your weakest subject and build up from there
• Use real-world examples to make concepts stick
• Time yourself on practice questions to simulate test pressure

This test isn’t just about knowing the material—it’s about applying it fast and accurately.

NAPT Scoring Explained for ASVAB Test-Takers

Your ASVAB score decides if you even need to take the NAPT for the Navy Nuclear Field program. Here’s how it works:

1. First, check your ASVAB scores.
   • Add up your VE (Verbal Expression) + AR (Arithmetic Reasoning) + MK (Mathematics Knowledge) + MC (Mechanical Comprehension). If the total is 235 or higher, move to the next step.
   • Also, add up your AR + MK + EI (Electronics Information) + GS (General Science). If this total is also 235 or higher, you don’t need the NAPT.
2. If your ASVAB scores don’t meet those numbers, you must take the NAPT.
   • After taking the NAPT, your new total must be:
     • VE + AR + MK + MC + NAPT ≥ 290 OR
     • AR + MK + EI + GS + NAPT ≥ 290
3. Both ASVAB line scores (without NAPT) must be at least 225.
   • If your ASVAB scores are below 225 in either category, you can’t qualify, even with a high NAPT score. No waivers allowed.
4. If you fail the NAPT but score 40 or higher, you can retake it in 90 days.
   • But only if you can prove academic improvement in math or science (like a college course or independent study program).
   • Retest minimum passing score: 50.

Bottom line: If your ASVAB scores are high enough, you don’t need the NAPT. If they’re borderline, you’ll need to pass the NAPT to qualify. If you don’t pass, you’ll need to prove you’ve improved before retesting.

What Happens on Test Day

• Arrive 30 minutes early at MEPS
• A Petty Officer or Test Administrator runs the session
• ID and SSN checked before testing
• No cell phones allowed
• Dry-erase board or digital whiteboard provided for calculations
• Escorted in/out if you leave the room
• Turn in all materials before exiting

Common Mistakes & How to Fix Them

1. Physics & Chemistry Struggles

• Know the difference between Newtonian vs. Aristotelian physics
• Expect velocity/time problems

2. Algebra & Trigonometry Errors

• Many struggle with the Acceleration formula—memorize it
• Some problems require rearranging formulas

3. Word Problems & Logical Thinking

• Read carefully—some questions test direction of motion
• Break multi-step problems into smaller parts

2-Week NAPT Study Plan

Week 1: Build Your Foundation

Day 1-3: Master the Math

• Algebra II: Solve for x, factoring, quadratic equations
• Geometry: Angle rules, Pythagorean theorem, area/volume
• Trigonometry: Sine, cosine, tangent, velocity formulas
  Goal: Get comfortable with formulas—you’ll need them.

Day 4-5: Science Crash Course

• Physics: Newton’s Laws, motion (vertical, horizontal, projectile)
• Chemistry: Balancing equations, atomic structure, reactions
  Goal: Learn how these concepts apply to real-world problems.

Day 6-7: Apply What You Learned

• Take a NAPT practice test (timed)
• Review every wrong answer—figure out why you missed it
  Goal: Find weak spots before diving into full test prep.

Week 2: Test Simulation & Strategy

Day 8-9: Focused Practice on Weak Areas

• Struggle with physics? Drill motion problems
• Messed up probability? Work through data prediction questions
• Go slow and correct mistakes—don’t rush
  Goal: Strengthen weak subjects before full test runs.

Day 10-12: Exam Simulation Mode

• Take a NAPT practice test under full timing conditions
• After the test: Review every mistake and retake those problem types
  Goal: Get faster while maintaining accuracy.

Day 13: Final Full-Length Test

• Take a realistic practice exam—strict time limit
• No notes, no help—simulate test day
  Goal: Build confidence under pressure.

Day 14: Light Review & Rest

• Look over key formulas—don’t cram
• Sleep early—test day success starts with a clear mind
  Goal: Be mentally sharp for the real thing.

Final Reminder: The NAPT is 80% problem-solving, not just memorization. Practice applying formulas, breaking down problems, and managing time. Stick to the plan, and you’ll be ready.

Your turn—Get at it

The NAPT is passable—if you prepare right. No shortcuts. You need math and science skills plus test-taking strategy.

Use NAPT practice tests, break down formulas, and focus on problem-solving. Stay consistent, follow the plan, and hit that passing score.
