State Test Score Trends Through 2008-09, Part 5: Progress Lags in High School, Especially for Advanced Achievers

This study from the Center on Education Policy examined trends in the achievement of high school students on the state reading/English language arts (ELA) and mathematics tests used for accountability under the No Child Left Behind Act (NCLB). Data included 40 states and the District of Columbia. Results showed that several states have experienced declines rather than gains on their state tests among high school students. Gaps between key student subgroups have widened in many states, particularly at the advanced level in math.
