Frequently asked questions
What is the Praxis Physics: Content Knowledge test (5266)?
Praxis 5266 is the ETS content-knowledge exam many U.S. states require to certify secondary physics teachers. It covers five domains — Nature of Science, Matter & Energy, Mechanics, Electricity & Magnetism, and Waves — in a computer-based, multiple-choice format.
How is 5266 different from the retired 5265 test?
5265 (Physics: Content Knowledge) was retired by ETS; 5266 is its current replacement and the version state boards now require. The subject matter is similar, but always confirm with your state's certification office that 5266 is the code they accept.
How long should I study before taking the exam?
Most candidates prepare for 3-6 weeks of consistent practice, more if physics coursework was a while ago. Start with the free 15-minute diagnostic to see which domains need the most work, then follow the weighted practice plan built around the official ETS proportions.
How does payment and access work?
Access is free — this is a non-commercial project and no payments are accepted. Create an account with your email and the full tool opens right away. If it helps, tell a colleague. Questions? Email contact@podlevskikh.com.
