The No Child Left Behind Act (NCLB) requires that all states install school & district accountability systems based on the results of student scores on annual tests. The goal is to press states & districts to act decisively to turn around failing schools & boost pupil achievement, particularly in reading & math. But little is known about what kinds of interventions are most likely to turn faltering schools into successful educational institutions. This report describes the interventions set forth for state & local policymakers as part of NCLB. It categorizes & reviews 17 interventions that have been attempted by states or school districts since 1989. Looks in detail at 3 interventions in: N.Y. State; Memphis, TN; & in Prince George's County, MD.Brady, Ronald C. is the author of 'Can Failing Schools Be Fixed' with ISBN 9780756732981 and ISBN 0756732980.
