Daniel Willingham has a post up explaining how the current measures states use to assess preschool quality are inaccurate.
He suggests that the cause of this may be that “Measuring things like years of experience and parental partnership is inexpensive and easy, and that’s nice. Someone at the school can submit this sort of data online. “
The data that states are using are isolated, easily gathered data points that someone sitting outside of that school thinks can demonstrate something inside of the school.
“Classroom measures, in contrast, are expensive. Someone with training has to actually observe what’s going on. That’s part of what goes into the “environment” measure, and it does look like that measure showed the most promise.”
