As graduation rates go down, school ratings go up

A new study by researchers at Rice University and the University of Texas-Austin finds that Texas' public school accountability system, the model for the national No Child Left Behind Act (NCLB), directly contributes to lower graduation rates. Each year Texas public high schools lose at least 135,000 youth prior to graduation -- a disproportionate number of whom are African-American, Latino and English-as-a-second-language (ESL) students.
