I am curious about this part. Why would outcomes be better for both non-depressive 3-year-olds and depressive 4-year-olds?: There is evidence that for some outcomes, Head Start had a differential impact for some subgroups of children over others. At the end of 3rd grade for the 3-year-old cohort, the most striking sustained subgroup findings were found in the cognitive domain for children from high risk households as well as for children of parents who reported no depressive symptoms. Among the 4-year-olds, sustained benefits were experienced by children of parents who reported mild depressive symptoms, severe depressive symptoms, and Black children.
