The relative importance of a group of cognitive variables in explaining the algebra achievement of high-ability eighth graders was investigated. Stepwise multiple regression analyses identified algebra prognosis test scores and performance in seventh-grade mathematics as the most influential predictors of algebra grades, whereas mathematics problem solving, the prognosis test, and IQ were shown to best predict achievement on a standardized algebra test. A discriminant analysis demonstrated the importance of the prognosis test in discriminating between students who successfully completed first-year algebra and those who dropped out of or failed the course. Although the study showed no sex difference in algebra achievement test scores, girls in the sample attained higher percentage grades for the course.
