Key PointsQuestion  What is the difference in school math and reading test scores by gestational age for children born at term? Findings  In this population-based cohort study of more than 500 000 children, there was no difference in school achievement between children born at 39 vs 40 weeks, and no evidence of better test scores between children born at 41 weeks vs 40 weeks. Scores were generally lower for children born at 37 to 38 weeks vs 40 weeks.
