A Data Archive for Project STAR and Beyond

This project will create a Project STAR public use data file.

Project STAR was a seminal, experimental study of the effects of reducing class size on student outcomes. The file will include 13 years of data on almost 12,000 students followed from kindergarten though high school. The STAR-and-beyond database will be publicly available, along with a user guide and documentation, to researchers and policymakers for continued analysis.
