Study: NCLB impacting classroom focus
According to a study from the Center on Education Policy, a significant number of school districts nationwide have reduced the amount of classroom time spent on subjects that are subject to testing under No Child Left Behind. The report indicates that schools are focusing more on reading and math at the expense of social studies, science and other subjects.

Study: Scores increasing since NCLB implementation
Student scores on state math and reading tests have improved, and the achievement gap between black and white students has narrowed somewhat since 2002, the year NCLB was implemented, but it isn't possible to determine whether NCLB was responsible.

Study: NCLB may not be working on the margins
Under NCLB, students in the middle have made the largest gains, while gifted students stagnate and the bottom 20% may even lose ground, according to a new University of Chicago study.
