Stat of the Week July 27, 2006
The release of Diplomas Count 2006 highlighted the variety of methods used to calculate graduation rates, and the discrepancies they create. A variety of measurement methods are employed because systems that track individual students (known as longitudinal data systems) are only now starting to be implemented. In a 2006 survey, the EPE Research Center found that 37 states link exit data to a unique student identifier, but a survey conducted by Achieve this year revealed that only three states have a longitudinal data system in place to track students as they move from kindergarten through college.
