Key Takeaways
- Praxis General Science Content Knowledge (5435) on this site is aligned to the current ETS General Science blueprint shown on the live 5436 test page.
- ETS currently lists 135 selected-response questions in 150 minutes with the $130 Praxis Subject Assessment fee tier.
- The official domain weights are 11% Nature and Impact of Science and Engineering, 31% Physical Science, 33% Life Science, and 25% Earth and Space Science.
- Passing scores are set by states or agencies rather than by one universal ETS cutoff.
- As of March 7, 2026, I did not find an official ETS nationwide redesign notice for the current General Science blueprint.
Praxis General Science Content Knowledge (5435)
This study guide supports Praxis General Science Content Knowledge (5435) prep while staying aligned to the current ETS General Science blueprint, which ETS presently lists on the live operational test page as General Science (5436).

What the 5435 vs 5436 Labels Mean
Candidates may see both numbers in official ETS materials:
- the live test page is currently listed as 5436
- ETS also still offers an official practice product labeled 5435
For your study plan, the important point is the current official blueprint, not the label alone. If your state or program names 5435, confirm whether it maps directly to the current 5436 administration.
Best Study Strategy
The highest-return sequence is:
- Build strong coverage in life science and physical science first.
- Add earth and space science as a full quarter of your prep.
- Keep inquiry, lab methods, graphing, and engineering design in regular rotation.
- Finish with mixed timed sets so you can switch domains quickly without losing accuracy.
2026 Planning Note
As of March 7, 2026, I did not find an official ETS notice announcing a nationwide blueprint redesign or replacement for the current General Science exam. The safest plan is to study the current ETS weighting, then verify your own state's score requirement before registering.
