An article in EdSource discusses the challenges affecting arts education in California, using recent data from the National Assessment of Educational Progress:
Students in the western U.S., which covers 13 states including California, showed slight improvements in their overall arts and music scores since 2008, but lagged in arts enrollment, with arts attendance dropping from 35 percent in 2008 to 33 percent in 2016. By contrast, almost 70 percent of students in the northeast were enrolled in a music or art class.
