This study explores the effects of the two-generation program Career"Advance"--which combines education and training for parents in healthcare with Head Start for children--on children's academic, language, mathematics, and inhibitory control followed for 3 years. The sample (collected in Tulsa, Oklahoma from 2011 to 2018) includes 147 children in the Career"Advance" group and 139 children in a matched comparison group (n = 286; 40% Black, 17%, White, 10% Hispanic, 33% Mixed Race, or Other Race; M = 3.6 years old; 47% female). Overall, the effect of Career"Advance" on child outcomes is neither greater nor less than Head Start alone. These findings suggest that children's developmental outcomes do not worsen or improve in the short term when their parents return to school.
