The problem of this study was performance on selected mathematics and reading assessment tests as predictors of achievement in remedial mathematics. The purpose of the study was twofold. The first was to determine the internal consistency of a locally developed remedial mathematics placement test and the mathematics section of the Pre-TASP Test. The second was to determine the predictive validity of performance on (a) the local remedial mathematics placement test, (b) the mathematics section of the Pre-TASP Test, and (c) the Descriptive Tests of Language Skills, Reading Comprehension Test in combination with demographic variables for mid-semester achievement, end-of-semester achievement, and course success in three levels of remedial mathematics at Richland College, Dallas, Texas.
