The relative predictive validity of girls' and boys' success in algebra is examined. Eighth-grade students took the Orleans-Hanna Algebra Prognosis Test. These prognosis test scores were correlated with grades that 519 girls and 421 boys subsequently earned in first-year algebra. Algebra grades of girls proved to be more predictable than those of boys ( p <.05). Comparison of the present findings with those of an earlier study suggest that no changes during a 14-year period in the differential predictive validity of the sexes is evident. Implications for counselors and teachers are drawn and discussed.
