For 2026 planning, ETS currently lists the live General Science exam as test code 5436 with 135 selected-response questions in 2 hours and 30 minutes at the $130 Praxis Subject Assessment fee tier. ETS also continues to offer an official practice test labeled General Science: Content Knowledge (5435), so candidates may encounter both codes in 2026 prep. The official study companion weights the blueprint 11% Nature and Impact of Science and Engineering, 31% Physical Science, 33% Life Science, and 25% Earth and Space Science. As of March 7, 2026, I did not find an official ETS notice announcing a nationwide redesign or replacement of the current science blueprint.

About the Praxis General Science Exam

Praxis General Science Content Knowledge (5435) is the broad-field secondary science teacher-certification practice bank on this site. It is aligned to the current ETS General Science blueprint, which ETS currently lists under operational test code 5436 and weights across nature and impact of science and engineering, physical science, life science, and earth and space science.

Praxis General Science Study Tips from Top Performers

1Weight your study time by the official blueprint: life science first, physical science second, Earth and space science third, and inquiry and engineering as a regular but smaller review block.
2Treat science-inquiry questions as evidence questions: identify the variable, the control, the measurement, and what conclusion the data actually supports before choosing an answer.
3In chemistry and physics, write down the core relationship first, such as conservation of mass, density, pH, Newtonian force relations, or wave-frequency-energy links, before doing option elimination.
4For life science, connect structure to function and process to outcome, especially in cell transport, genetics, evolution, ecology, and homeostasis.
5In Earth and space science, anchor your reasoning to systems: plate interactions, rock-cycle transitions, energy transfer in the atmosphere-ocean system, and Earth-sun-moon geometry.

Frequently Asked Questions

Is Praxis General Science 5435 the same as 5436?

In current official ETS materials, the live operational test page is listed as General Science (5436), while ETS still sells an official practice test titled General Science: Content Knowledge (5435). For practical prep, the safest approach is to study the current 5436 blueprint and confirm with your state or program which code they reference.

How many questions are on Praxis General Science and how long is it?

ETS currently lists the live General Science exam as 135 selected-response questions in 2 hours and 30 minutes. That gives you less than 70 seconds per item on average, so pacing matters even though many questions are concept-based rather than computation-heavy.

What content matters most on Praxis General Science?

Use the official weighting as your study plan: Life Science is largest at 33%, Physical Science is 31%, Earth and Space Science is 25%, and Nature and Impact of Science and Engineering is 11%. In practice, that means almost two thirds of your time should go to life and physical science, but you still need dependable Earth and space coverage because one quarter of the exam sits there.

What passing score do I need?

Praxis passing scores are set by states, agencies, and educator-preparation programs rather than by one universal ETS cutoff. ETS points candidates to the state requirements lookup, so confirm your exact score requirement before registering or sending score reports.

How much does Praxis General Science cost?

The current ETS test page lists General Science in the selected-response Praxis Subject Assessment fee tier, which is $130. Always confirm the live total in your ETS account before checkout in case ETS updates taxes, service fees, or bundled offers.

What changed for Praxis General Science in 2026?

As of March 7, 2026, I did not find an official ETS notice announcing a nationwide redesign, new cut-score policy, or replacement code for the current General Science blueprint. The notable current context is simply that ETS uses 5436 on the live test page while an official practice product still uses 5435, so you may see both numbers in prep materials.

How should I study for Praxis General Science efficiently?

Study by blueprint weight and by weakness. Start with life science and physical science, then review Earth and space science, and finish with inquiry, lab methods, and engineering-design scenarios. Mixed timed sets matter because the exam expects you to switch quickly across biology, chemistry, physics, geology, and astronomy without losing precision.
