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
