Head Start’s benefits fade quickly, writes Jay Greene, but Health and Human Services is “up to its old tricks of delaying research whose results are likely to undermine their darling program, Head Start.”
In a letter to HHS Secretary Kathleen Sebelius, five senators asked “why the latest round of results of the congressionally mandated study have not been released four years after data collection was complete and one year after the report was scheduled to be released.”
In 2010 I told you about how the Department of Health and Human Services delayed the release of the previous round of disappointing research results about the lasting effects of Head Start. When the extremely high quality study, involving a random-assignment design on a representative sample of all Head Start programs nationwide, was finally released three years after the data collection was complete, it found that students randomly assigned to Head Start performed no better on cognitive measures by the end of kindergarten and first grade.
Despite this, HHS declared the program a huge success. “Research clearly shows that Head Start positively impacts the school readiness of low-income children,” said Sebelius.
