Exact Path Diagnostic and Ohio State Test (OST) Correlational Study

Exact Path diagnostic assessment scores are highly correlated to Ohio State Test (OST) math and English language arts scores across grades (3-8) and testing windows. High correlations were also found between Exact Path diagnostic Grade 2 and OST Grade 3 scores, and for middle school students that took the Exact Path mathematics diagnostic assessment and Ohio's Algebra I and Geometry end-of-course tests. These results support use of Exact Path as an early indicator of student achievement in mathematics and English language arts, and a strong predictor of success on Algebra 1 and Geometry EOC tests.

In preparation for OST assessments, educators can use Exact Path diagnostic results to:

• Identify students who need additional support
• Prioritize content areas to focus on
• Inform data-driven instruction and targeted intervention
• Increase student readiness for Algebra 1 and Geometry
