On November 1, 1998, Health & Education Research Operative Services, 
(HEROS), Incorporated released the Project STAR (kindergarten to third 
grade) public access data set. The release of this data to the research 
community is intended to facilitate further discussion of the effects 
of reduced class size in education.  This data set includes student 
achievement data from the four years that Project STAR operated as well 
as student and teacher demographic data. All personal information that 
could be used to identify individual students and teachers has been 
removed. Over the next two years, additional research data from Project 
STAR and the STAR Follow-up Studies will be appended to the public 
access data set.
