The passage of the No Child Left Behind law in 2001, which measures student achievement based on English and math scores, has pressured schools to cut the arts. A 2006 survey by the Center on Education Policy found that 44 percent of school districts had increased time for English and math while cutting time for other subjects. And a follow-up study done in 2008 found that 16 percent had cut elementary school class time for music and art. The declines have been sharpest in low-income schools. Earlier this year, the Obama administration released a report from the President's Committee on the Arts and the Humanities. In an effort to check the long decline in arts education, the report called for more money and better teaching strategies. It also called for a new approach that doesn't treat arts education as a frill that can be cut every time budgets get tight.
