Executive function at the beginning of kindergarten, compared with low socioeconomic status executive function, by SES quintile (Cognitive flexibility)

Unadjusted (M1S) Adjusted by race (M2S) Fully adjusted (M3S)
Low-middle SES 0.144***(0.047) 0.100**(0.048) 0.098**(0.049)

Note: SES refers to socioeconomic status. Model 1 (M1S) shows the baseline unadjusted standard deviation score for each socioeconomic group, relative to low-SES children. Model 2 (M2S) shows each group's relative performance after controlling for rache/ethnicity. Model 3 (M3S) shows relative performance after adjusting for all family and child characteristics, pre-K schooling, and enrichment activities with parents. See Appendix A and Tables D2 and F2.
