Welcome to the Profit of Education website. Continuing the conversation begun in the book Profit of Education, we discuss the latest economic evidence on education reform.

School starting times

Back in August I wrote about a study suggesting that moving school starting times later really benefits adolescents. A new article by Peter Hinrichs comes to the opposite conclusion.

In 1997-98, Minneapolis moved the high school starting time from 7:15 to 8:40. St. Paul did not. Now Minneapolis and St. Paul are otherwise pretty similar. (Pace Garrison Keillor.) Hinrichs compared ACT scores in the Twin Cities before and after the change in Minneapolis. If extra sleep helps teenagers you’d expect scores to improve in Minneapolis relative to St. Paul.

Nope. Nada. No detectable difference.
