Although grading practices and standards differ across teachers and schools, the research body shows grades remain very predictive because those differences are small relative to students' actual academic preparation. → Key Questions: How important are course grades as predictors of students' future success? 2025 q2 i? GPAs average out differences across teachers, making them particularly good indicators of preparation for academic work beyond any individual class. → Key Questions: How important are course grades as predictors of students' future success? 2025

q2 · i? · review · r?

The interview acknowledges "differences in grading practices and standards across teachers and schools" but reports the research body shows grades are very predictive, with teacher differences small relative to preparation. It adds GPAs average out teacher differences. No effect sizes are printed.

"But since the research body shows that, across all students, grades are very predictive, differences across teachers are small relative to students' actual academic preparation."

Discussion¶

Related Claims¶

• SAT scores underpredict the academic performance of high school girls, who average lower scores than boys despite higher grades — related
• Studies finding grades less predictive often use restricted samples or weighted or self-reported GPAs, which are less accurate — related
• Prior GPA was the best predictor of students' course grade, whether or not students used courseware. — a narrower finding that bears on this claim
• School-level differences in grades are small and largely explained by attendance and course characteristics — a narrower finding that bears on this claim
• Teacher effects account for about one-fifth of within-student variation in course grades but average out of GPAs — a narrower finding that bears on this claim
