Exact Path Diagnostic and North Carolina End-of-Grade (EOG) / End-of-Course (EOC) Exams Linking and Correlational Study

Exact Path diagnostic assessments yield highly accurate predictions of student results on the North Carolina End-of-Grade (EOG) tests. This research study linked fall, winter, and spring Exact Path diagnostic scores to spring EOG scores across grades 3-8 in mathematics and reading. Linking study results demonstrated that Exact Path Diagnostic scores can be used to predict whether students would be above or below the EOG proficient cut score with 77%-88% accuracy.

In preparation for NC’s EOG/EOC tests, educators can use Exact Path diagnostic results to 

• predict students’ proficiency on the EOG
• identify students who need additional support 
• prioritize content areas to focus on 
• inform data-driven instruction and targeted intervention
