California graduation study

Study: 50,000 fewer graduated after California exit exams began
California graduation rates fell significantly in 2006, with an analysis showing that around 50,000 fewer students statewide earned diplomas last year compared to previous years, just as the state began requiring exit exams, according to UCLA researcher John Rogers. State officials have taken issue with those findings, saying Rogers' analysis is based on incomplete data. San Francisco Chronicle (5/8)
