Since 1965, the Head Start program has served low-income 3- and 4-year-old children and their families with comprehensive early education and support services. Programs provide services focused on the "whole child," including early education addressing cognitive, developmental, and socio-emotional needs; medical and dental screenings and referrals; nutritional services; parental involvement activities; referrals to social service providers for the entire family; and mental health services. All Head Start programs are required to complete the Program Information Report (PIR) on an annual basis. The PIR collects data on all children and pregnant women who participate in Head Start at any point during the program year, including those who do not complete the year. This fact sheet uses information reported through PIR to describe the children and families enrolled in the Head Start preschool program and the services provided to them during the 2013-2014 program year.
