Abstract, Study Design: We assessed 14,350 term infants and 1200 32–36 6/7 weeks gestation infants followed in the Early Childhood Longitudinal Study Kindergarten 2011 cohort for classroom performance in kindergarten-fifth grade.

Results, first paragraph: Of the 18,180 children enrolled in the study, 14,350 children were determined to be term gestation of at least 37 weeks', 780 were born at 35–36 6/7 weeks gestation, and 420 were born at 32–34 6/7 weeks gestation. 120 were very preterm (28–31 6/7 weeks gestation) and 30 were born extremely preterm (<28 weeks gestation). Given the small sample size, and the focus of this study, children who were born at less than 32 weeks' were excluded from analysis. Gestational age was unable to be determined for 2480 children as their parents did not complete the birth history section; these children were excluded from the analysis.
