This article reports on the draft bill that outlines key House members' plans to change the accountability system by measuring students' academic growth and adding other indicators to those in reading and mathematics. The release this week of a preliminary proposal for reauthorizing the No Child Left Behind (NCLB) Act starts a busy fall in Congress, as both the House and the Senate try to revamp the NCLB accountability system and ramp up efforts to improve struggling schools. Most education groups reacted cautiously to the draft as they considered the impact of changes proposed in the House Education and Labor Committee document, which committee leaders called a "work in progress." On the Senate side, lawmakers worked on an NCLB bill throughout the August recess and are aiming to have their bill win the Senate's approval by the end of the year.
