If memory serves there were lot of studies done a few years ago on Head Start’s impact on later academic performance, but the results were inconclusive and (IIRC) most positive effects of Head Start enrichment pretty much petered out fairly quickly as kids started getting older.
What was the final verdict on Head Start, or was there one?
I can’t speak to Head Start specifically, but I do know that recently completed long-term studies of four different early education programs for low-income children showed they did substantially better than their peers who hadn’t been in the programs.
I don’t have any of the studies in front of me now but I did study them ten years ago in graduate school. They showed just what you said. There is an increase in academic performance while the children are in Head Start but it drops off rapidly after they are out of the program until their is no detectable effect three or more years later.
In this case I think the “no effect” result meant that academically, after a few years they were back down to the same level their non-head start economic peers were performing at, not the “average”.
The latest studies, however, show that while academic performance slacks off, Head Start participants are more likely to graduate from high school, attend post-secondary training, stay off drugs, stay off public assistance, blahblahblahallthatgoodstuff. There was a news article on just this topic not too long ago but damned if I can remember where. I have access to the study via my uni’s super-secret server; I’ll see if I can dig it up for you.
