How It Works in the Classroom

This Grade 8 Ohio OST Science practice test is designed for flexible use:

• Administer as a full-length mock test (2 sessions, ~90–120 minutes) to simulate real testing conditions

• Use domain-by-domain practice (3 weeks) for focused review of each science area

• Assign as a benchmark or diagnostic assessment to guide instruction

• Use for small-group intervention and reteaching

• Track progress using the built-in data tracker chart (page 11)
