Children who attend Head Start reach developmental milestones two and a half to five months earlier than children who do not. This finding holds true across a variety of developmental areas. Child assessment data was collected on all three and four year-olds enrolled in 30 California Head Start programs. Statistical analysis was conducted on a subset of this group totaling 9,665 children to determine how much the children benefited from participating in Head Start as three-year-olds.
