(Guest Post by Matthew Ladner)
A conversation with Robert Pondiscio convinced me that it would be a good idea to balance progress with overall scores. Growth is dandy after all, but it is not the end-all-be-all. So here goes with math- statewide scores for 8th graders in 2015 by overall cohort progress between 4th graders in 2011 and 8th graders in 2015. Bonus-more states labeled. It’s a slow process so if I missed a desired state just let me know in the comments.
So the high performing usual suspects do better in this chart clustered over on the right side of the horizon. The 2015 NAEP math swoon hit some states very hard- yes I’m looking at you Florida, Maryland and North Carolina. Between 2013 and 2015 these states experienced a 6 point, 4 point and 5 point drops in 8th math respectively. Florida’s case was very odd as statewide charters and Miami Dade escaped the swoon. We will see what happens when the new data is released for in 2017 in January.
