Grades 3-8
EOC
Brief
Exact Path diagnostic assessments yield highly accurate predictions of student test results on Ohio’s State Test (OST). Strong correlations were also found between Exact Path diagnostic scores from grades 1 and 2 and OH OST grade 3 scores, and OH EOC scores in Algebra 1, Geometry, and English 2. These findings suggest that the assessments measure similar skills and knowledge, and that Exact Path is a strong predictor of OH OST performance across grades 1-12. In preparation for OH OST assessments, educators can use Exact Path diagnostic results to:
- Identify K-12 students who need additional support
- Prioritize content areas to focus on
- Inform data-driven math, reading, and OH EOC instruction and targeted intervention
- Help ensure that students are on track to meet academic standards
