This study investigated the degree to which it was possible to identify students who were likely to fail the Ohio Ninth Grade Proficiency Test (ONGPT) from data contained in their academic records. The criterion measure was student scores on the Trial Test of the ONGPT, a measure selected because it provided scores that could be correlated, as opposed to the pass/fail scores reported through the ONGPT. The predictor variables were gender, middle school grade point average, educational program, and eighth grade subtest scores on the California Achievement Test (CAT). A sample of 52 students was used to study the feasibility of an expanded study. The results indicate a high correlation between success on the Writing subtest of the ONGPT and scores on the Language portion of the CAT. Reading ONGPT scores correlated with Reading CAT scores, and Mathematics ONGPT scores correlated with Mathematics CAT. The highest predictor for the Citizenship ONGPT was the Mathematics CAT. Relationships between the standardized achievement tests and ONGPT were strong enough to help identify students who need additional assistance to prepare for the ONGPT.
