NES Physics (308) Exam Secret

About this resource

The NES Physics (308) examination is a National Evaluation Series computer-based test required for secondary physics educator certification in adopting states, including Arizona, Oregon, and Wisconsin. This comprehensive test preparation guide outlines the official exam framework, domain weighting, passing score benchmarks, and time management strategies to help educator candidates achieve credentialing success.

NES Physics (308) Exam Specifications & Test Structure

Administered by Pearson Education and Evaluation Systems, the NES Physics test assesses prospective physics teachers on both foundational scientific inquiry and advanced physical principles. The test is administered as a computer-based examination at authorized Pearson VUE testing centers.

• Format: 150 multiple-choice questions.
• Testing Duration: 3 hours 45 minutes total appointment time (225 minutes of dedicated testing time, plus 15 minutes for the introductory tutorial and nondisclosure agreement).
• Passing Scaled Score: 220 (scores are reported on a scaled range from 100 to 300).
• On-Screen Testing Aids: An on-screen scientific calculator and a constants and formulas pop-up reference sheet are accessible throughout the test.
• Retake Policy: Candidates who do not achieve a passing score must wait a minimum of 30 calendar days before retesting.

Content Domains & Competency Breakdown

The examination covers five core domains comprising 15 comprehensive competencies:

1. Domain I: Nature of Science and Engineering Design (~19% of exam, ~28 questions)
   Covers principles of scientific inquiry, experimental design, systematic error analysis, the societal context of scientific discovery, and the iterative engineering design process (Competencies 0001–0002).
2. Domain II: Mechanics (~31% of exam, ~47 questions)
   Represents the largest single test domain. Focuses on 1D and 2D kinematics, vector operations, Newton’s laws of motion, frictional forces, universal gravitation, work-energy theorems, conservation of linear and angular momentum, rotational dynamics, and fluid mechanics (Competencies 0003–0006).
3. Domain III: Electricity and Magnetism (~22% of exam, ~33 questions)
   Examines electrostatics, Coulomb’s law, electric field mapping, electric potential, DC and AC circuit analysis, Ohm’s law, magnetic fields, electromagnetic induction, Faraday’s law, and foundational Maxwell relationships (Competencies 0007–0009).
4. Domain IV: Waves, Sound, and Optics (~14% of exam, ~21 questions)
   Tests wave characteristics, acoustic wave propagation, Doppler shifts, geometric optics (Snell’s law, reflection, refraction, ray tracing for lenses and mirrors), and physical optics (interference, diffraction, polarization) (Competencies 0010–0012).
5. Domain V: Modern Physics (~14% of exam, ~21 questions)
   Addresses special relativity, thermal physics concepts, quantum phenomena, wave-particle duality, the photoelectric effect, atomic models, nuclear decay modes, half-life calculations, and the Standard Model of fundamental particles (Competencies 0013–0015).

Study Strategy & Time Management Guidelines

Mastering the NES Physics (308) exam requires balancing conceptual clarity with mathematical problem-solving speed:

• Prioritize High-Weight Domains: Domains II (Mechanics) and III (Electricity & Magnetism) constitute 53% of all questions (~80 items). Candidates should dedicate more than half of their preparation schedule to active practice problems in these areas.
• Pacing Budget: Allocating 225 minutes across 150 questions provides an exact budget of 90 seconds (1.5 minutes) per question. Candidates should complete qualitative and conceptual questions in 45–60 seconds, leaving up to 2 minutes for complex multi-step kinematics, circuit calculations, or modern physics conversions.
• Formula Sheet Proficiency: While an on-screen reference sheet is provided, candidates should be thoroughly familiar with physical constants and standard notation to avoid losing testing time navigating reference windows.
