A current guide to the 2 hour 30 minute Praxis 5436 exam, including physical science, life science, Earth and space science, nature and impact of science and engineering, science practices, teaching tasks, and periodic-table support.
Praxis 5436 is a broad secondary science exam. Preparation should pair general science content with science and engineering practices, data interpretation, models, classroom investigations, student thinking, and instructional decision-making.
Use these ETS structure points to organize General Science preparation.
ETS lists 2 hours 30 minutes and 135 selected-response questions for General Science 5436.
Physical Science is the largest category, with about 50 questions and 37% of the examination.
Half or more of the questions integrate a Science and Engineering Practice.
About one-quarter to one-third of questions apply content to a Task of Teaching Science.
Physical Science carries the largest weight and includes matter, energy, atomic and nuclear structure, chemistry, mechanics, electricity, magnetism, optics, waves, thermodynamics, and quantitative reasoning.
ETS emphasizes Science and Engineering Practices, so candidates should practice using evidence, interpreting data, evaluating models, designing investigations, applying engineering design, analyzing errors, and explaining phenomena across all domains.
Teaching-task questions place science content in classroom contexts. Study should include student misconceptions, diagnostic questions, lab safety, resource selection, model critique, data displays, explanations, and instructional next steps.

Praxis General Science 5436 measures the science knowledge and competencies needed for beginning practice as a teacher of general science. ETS lists a 2 hour 30 minute computer-delivered exam with 135 selected-response questions.
HiraEdu prepares candidates around the official ETS blueprint: Nature and Impact of Science and Engineering has about 20 questions and 15% of the examination, Physical Science has about 50 questions and 37%, Life Science has about 35 questions and 26%, and Earth and Space Science has about 30 questions and 22%. ETS notes that half or more of the questions integrate a Science and Engineering Practice, and about one-quarter to one-third apply content to a Task of Teaching Science. Candidates do not need calculators, but a periodic table and selected constants/conversion factors are available as Help screens.
ETS lists a 2 hour 30 minute time limit for Praxis 5436.
The official ETS study companion lists 135 selected-response questions.
Physical Science is the largest domain, with about 50 questions and 37% of the examination.
Yes. ETS states that half or more of the questions integrate a Science and Engineering Practice.
ETS states that calculators are not needed. A periodic table and selected constants or conversion factors are available as Help screens.
Plan review around Nature and Impact at 15%, Physical Science at 37%, Life Science at 26%, and Earth and Space Science at 22%.
Use estimation, unit reasoning, formulas, periodic-table information, constants, and conversion factors because ETS says calculators are not needed.
For each content topic, practice one teaching decision involving investigation design, safety, student thinking, model selection, or explanation feedback.
Complete 135-question mixed science sets under 2 hour 30 minute timing and review errors by domain and science practice.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
