Given that the current population of US school kids is the most intensively tested school age cohort in history via the NCLB requirementswhat have learned through that testing that we did not know before? What insights has this torrent of performance metrics given us about student, teacher and school performance?
I ask because I have not seen any layman level articles or papers referencing this presumed river of performance data that addresses any new or interesting facts or conclusions. I’m sure there must be something profound to come out of all this.
Is there anything?
