Do you agree with James Heckman, a Nobel prize-winning economist, that the low test scores of Blacks is due to poverty during their preschool years?

At ages five and six, the average black student is behind 85 percent of whites on test scores.

That pattern convinced James Heckman that traditional methods of school reform came too late in a child’s life to make much difference. He concluded that “schools and school quality contribute little to the emergence of test-score gaps among children.” He therefore urged reformers to “catch ‘em young,” and focus on the pre-kindergarten years when children are three- and four-years-old, and even on children from birth to age three.

Prof. Heckman based this approach on studies of enrichment programs for children in poverty who were followed until they were adults. The most influential of these programs was at the Perry Preschool in Ypsilanti, Michigan. From 1962 to 1967, Perry provided three-year-old poor black children with two and a half hours of daily preschool. Perry also placed teachers with advanced degrees in the children’s homes, where they spent 90 minutes each week instructing the Perry parents on child rearing. The Perry students were then compared with a control group at ages 14, 15, 19, 27, and 40.

The follow-up studies suggested that the children who attended Perry and whose parents received home visits were more likely to graduate from high school and less likely to go to jail. The Perry girls were less likely to become pregnant as teenagers, and the Perry boys earned more money than boys in the control group. After comparing the Perry students’ outcomes with those of the control group, Heckman calculated that the economic benefits of early childhood education yielded “rates of return are [from] 15% to 17%. The benefit-cost ratio is eight to one.”
