There was a short article in the NY Times about a link in NYC schools between those who do well academically and arts offerings. (Is it the chicken or the egg?)
From the article:
"The report, which analyzed data collected by the city’s Education Department from more than 200 schools over two years, reported that schools ranked in the top third by graduation rates offered students the most access to arts education and resources, while schools in the bottom third offered the least access and fewest resources. Among other findings, schools in the top third typically hired 40 percent more certified arts teachers and offered 40 percent more classrooms dedicated to coursework in the arts than bottom-ranked schools."
Here's a link to the full report.
