The Praxis II Science (5905) is the Science subtest within the Elementary Education: Three Subject Bundle (5901). It is designed to measure whether a prospective elementary teacher has the broad scientific knowledge and reasoning skills necessary to teach science at the K–6 level.
The exam is computer delivered and consists of 55 selected-response questions completed in 60 minutes. An on-screen scientific calculator is provided. It is built into the computer-delivered testing system—you may not bring your own calculator.
Because the calculator interface may feel different from a handheld model, you are strongly encouraged to practice using the official version before test day. You can access the practice calculator here.
The test is divided evenly across three major content categories:
- Earth and Space Science (approximately 17–18 questions, 33%)
- Life Science (approximately 18–19 questions, 33%)
- Physical Science (approximately 18–19 questions, 33%)
Across all three categories, questions often assess scientific inquiry skills, such as interpreting data tables, graphs, diagrams, and experimental scenarios. Many items are framed in elementary classroom contexts, requiring you to apply scientific knowledge to teaching situations.
Overall, the 5905 evaluates both foundational science content and your ability to apply that content in an instructional setting.
