They are given outside support to help them base their plans on the best available analyses of student needs. Its still early，but officials are already seeing stronger test scores and a narrowing achievement gap.But some critics are worried. “We risk producing something thats very expensive and time-consuming, and that will give educators a lot of trouble. ” says Frederick Hess. “Before we spend all that extra money, Id much rather see if we can figure out how to get 50 percent more instructional time out of the current school day. ”(328W)1.
