Here’s an excerpt from an NPR article/interview with Sir Ken Robinson. Basically, he says
1.) Look at the curriculum. Are there arts in addition to STEM?
2.) Look at the quality of teaching.
And 3.):
“Look at what’s on the walls. Is there kids’ work on the walls? Exhibitions? That also taps into the overall culture — you know, what sort of values are school promoting and how closely does it work with parents and the broader community? I think these are all reasonable criteria for the health and vitality of a school.”
