About The Study: The findings of this study of more than 500,000 children suggest that there is no evidence of a difference in math and reading scores over grades 2 to 11 among children born between 39 and 40 weeks' gestation, and overall no evidence of better scores among those born at 41 weeks' gestation compared with 40 weeks' gestation. The results can further inform decisions on delivery timing at term birth by offering insights into long-term associations of delivery timing with cognitive development and school achievement.
