This article discusses how President's Bush's proposals to expand educational accountability from the elementary and middle grades to high schools would mean more testing for teenagers, individual student plans to promote achievement, and financial incentives for teachers to help students meet their goals. Mr. Bush's campaign proposals, unveiled at the Republican National Convention, are part of a much broader wave of improvement efforts focused on high schools. At the heart of President Bush's focus on high school education is a proposed series of reading and mathematics tests in 9th, 10th, and 11th grades to help pinpoint which students may be struggling and in which areas. These tests would go beyond the current requirements under the 2- and a half-year-old No Child Left Behind Act championed by Mr. Bush.
