CURRICULUM GUIDE
About the Oklahoma Science Curriculum
How OAS Science Works
Oklahoma sets its own science standards through the Oklahoma Academic Standards, organized around disciplinary core ideas, science practices, and crosscutting concepts by grade.
How Oklahoma Differs
Oklahoma adopted its own OAS Science framework rather than NGSS, introducing integrated physical and life science strands starting in Kindergarten and maintaining that structure into high school.
How Oklahoma Science Progresses
Students move from foundational life and earth science in elementary grades through deeper investigation of matter and ecosystems in middle school, into integrated 9th and 10th grade science.
How Oklahoma Assesses Science
OSTP Science tests are administered in 5th and 8th grade; high school students take the Biology End-of-Instruction exam alongside other OAS-based assessments for graduation readiness.
