The Kansas City, Missouri, School District's Early Childhood Development program consists of the Parents as Teachers (PAT) and Early Learning Centers (ELC) programs. Both PAT and the ELC programs have a screening component, with PAT screening children from 12 to 36 months of age and ELC screening 3-, 4-, and 5-year-old children. The ELC instructional curriculum directly intervenes to eliminate developmental delays of at-risk students before they enter kindergarten. PAT is an educational program for parents of children younger than 6 years of age. The programs are designed to reduce the number of children with developmental delays through parent education and active parent involvement in the early learning processes of their children. A fifth-year evaluation of the two programs yielded the following findings: (1) all ELCs began each year at capacity (1,000 children) and capacity was maintained by drawing students from a waiting list; (2) enrollment in PAT has grown steadily since the first year of implementation to a high of 6,814 parents in 1990-91; (3) a total of 20,868 families have benefitted from PAT since the program started in 1986; (4) the number of children screened by the programs increased steadily through the years, but so did the number of children found to be at risk for developmental delays; (5) in 1990-91, 41% of the 1,896 1- to 3-year-old children screened by PAT were found to be at risk, as were 72% of the 4,329 3- to 5-year-old children screened at ELCs; (5) for about 25% of the ELC students, the programs worked to curb delays and allowed the students to catch up academically with their peers; and (6) a total of 72% of the ELC children who were old enough to enter kindergarten every year did not do so.
