Mike Petrilli of the conservative Thomas B. Fordham Institute got an early release of the NAEP scores and did a good job of analyzing them.

A cheerleader for testing, accountability, and choice,  he has to admit that the overview is bleak.

Minor bright spots, but overall stagnation.

He writes:

“As feared, the new results from the National Assessment of Educational Progress show that national trends are mostly flat. Coming on the heels of some modest declines in 2015, the 2017 scores amount to more bleak news. It’s now been almost a decade since we’ve seen strong growth in either reading or math, with the slight exception of eighth grade reading. There’s no way to sugarcoat these scores; they are extremely disappointing.”

The big gainers appear to be two of the lowest scoring jurisdictions: Mississippi and D.C.
