The National Council on Measurement in Education (NCME) is a professional organizationįor individuals involved in assessment, evaluation, testing, and other aspects Correlations between the two types of high school grades (computed for each of 18 colleges) ranged from.59 to.85. An interesting peripheral finding was that grades provided by students' high schools were stronger predictors of FGPA than were students' self-reported high school grades.
The study provided some support for this hypothesis and showed that the prediction of college grades can be improved using information about high school socioeconomic status. Attributing overprediction to measurement error, however, is not fully satisfactory: Might the measurement errors in the predictor variables be systematic in part, and could they be reduced? The research hypothesis in the current study was that the overprediction of Latino and African-American performance occurs, at least in part, because these students are more likely than White students to attend high schools with fewer resources. Under various plausible models, this phenomenon can be explained in terms of the unreliability of predictor variables. Research has often found that, when high school grades and SAT scores are used to predict first-year college grade-point average (FGPA) via regression analysis, African-American and Latino students, are, on average, predicted to earn higher FGPAs than they actually do.
