Three tests published by the Mathematics Association of America were administered during the first week of classes to students enrolling in algebra, pre‐calculus algebra, and trigonometry classes. Scores were correlated with grades using eta and Pearson correlations. Eta coefficients were significant for all classes. The Pearson correlations were significant for the two algebra courses but not for the trigonometry course. It was concluded that the algebra tests were valid as predictors of course grade but no support was found for the validity of the trigonometry test.
