A focused guide to the 60-minute Praxis 7814 science CKT subtest, including Earth and Space Sciences, Life Sciences, Physical Sciences, engineering applications, science practices, models, student misconceptions, and instructional decision-making.
Praxis 7814 tests science content knowledge through the work of teaching. The strongest preparation connects elementary science concepts to investigations, representations, student thinking, scientific explanations, vocabulary, and evidence-based instructional choices.
Use these ETS structure points to keep science CKT preparation precise and classroom-facing.
ETS lists 60 minutes and 47 selected-response questions for Science CKT 7814.
Earth and Space Sciences has about 11 to 15 questions and 30% of the examination.
Life Sciences and Physical Sciences each carry about 13 to 17 questions and 35%.
About 80% of questions measure specialized science content knowledge for teaching.
Praxis 7814 expects candidates to know science ideas and use them in teaching decisions. Items may involve selecting goals, choosing investigations, evaluating resources, diagnosing student misconceptions, modeling scientific language, or critiquing explanations.
Earth and Space Sciences covers astronomy, Earth systems, weather, climate, natural resources, and hazards. Life Sciences covers structures, processes, heredity, adaptation, ecosystems, and interdependence. Physical Sciences covers matter, forces, motion, energy, and interactions.
ETS states that engineering, technology, and application questions draw from Earth and Space, Life, or Physical Sciences and report into those categories. Practice should include design solutions, models, evidence, data, and how students reason about phenomena.

Praxis Elementary Education: Science CKT 7814 is the science Content Knowledge for Teaching subtest in the Praxis 7811 series. ETS lists a 60-minute computer-delivered subtest with 47 selected-response questions.
HiraEdu prepares candidates around the official ETS blueprint: Earth and Space Sciences has about 11 to 15 questions and 30% of the examination, Life Sciences has about 13 to 17 questions and 35%, and Physical Sciences has about 13 to 17 questions and 35%. Engineering, Technology, and the Application of Science questions draw from those three science domains and are reported within them. ETS also describes the subtest as about 20% student-curriculum content knowledge and about 80% specialized content knowledge for teaching elementary science.
ETS lists a 60-minute time limit for the Science CKT 7814 subtest.
The official ETS study companion lists 47 selected-response questions.
The domains are Earth and Space Sciences at about 30%, Life Sciences at about 35%, and Physical Sciences at about 35%.
ETS states that Engineering, Technology, and the Application of Science questions cover topics from Earth and Space, Life, or Physical Sciences and are reported in those categories.
CKT means Content Knowledge for Teaching. ETS says about 80% of the Science CKT questions measure specialized content knowledge used to teach elementary science.
Schedule review around 30% Earth and Space Sciences, 35% Life Sciences, and 35% Physical Sciences.
For each content topic, practice one classroom decision: investigation selection, resource evaluation, misconception diagnosis, vocabulary support, model critique, or explanation feedback.
Review sample student claims, drawings, tables, models, and explanations, then identify evidence of understanding or partial conceptions.
Complete 47-question mixed science CKT sets under 60-minute timing and review misses by domain, practice, and teaching task.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
