“Starting school later in the day for middle and high school students would likely increase student achievement, especially for disadvantaged teens, according to a 2011 study by the Hamilton Project at the Brookings Institution,” writes The Wall Street Journal’s Sue Shellenbarger in a recent Q&A for in the paper. Shellenbarger highlights The Hamilton Project discussion paper, “Organizing Schools to Improve Student Achievement: Start Times, Grade Configurations, and Teacher Assignments” in which, Brian A.

Jacob and Rockoff propose three organizational reforms to improve student performance at moderate cost: 1) Starting school later in the day for middle and high school students; 2) Shifting from separate to elementary and middle schools to K-8; 3) allow teachers to teach the same grade level for multiple years or having teachers specializing in the subject where they appear most effective.
