"Although kids who are involved in the arts do tend to test better, there’s no direct cause-and-effect evidence that participation actually helps raise scores.
This sounds like awful news and justification to slash school arts programs even further, right? But “dismissing the arts if they don’t directly boost scores is a big mistake,” says Richard Kessler, executive director of the Center for Arts Education in New York City. “In fact, plenty of research shows that children who spend time in school doing visual art, performing music or dance, or even acting in a play gain a whole set of creative and analytical skills that are quickly disappearing from the rest of the curriculum.”
