This study was designed to identify variables which account for successful performance in a remedial community college mathematics laboratory. Mathematics pretest scores, mathematics skills test scores, attendance time, age, gender, and attitude were used to help predict achievement. The sample consisted of the total population in the mathematics laboratory during the fall of 1987 (247 students) and 1988 (233 students). Gender, time of attendance (day or evening), and attitude were shown to be independent of the variable grade. The regression equation found the pretests, age, and the mathematics skill test were significant in predicting students' final grades and accounted for 31 percent of the variance. Ten references are listed. (YP)
