Note. Mean values are presented with standard deviations in parentheses. The ECLS-K estimates were derived from data made publically available by NCES (see online supplementary information file and nces.gov/ecls/). All ECLS-K measures shown were collected during the fall of kindergarten (i.e., 1998), and SECCYD measures were collected during the 54-month interview (i.e., preschool; 1995–1996), except for “mother’s education” and “mother’s age at child’s birth,” which were both collected at the 1-month interview. The ECLS-K variables were weighted using the C1CW0 weight to generate nationally representative estimates.
