Mercedes Scheider followed the contretemps around Campbell Brown’s misuse of NAEP data. She decided she would try to educate Campbell.


Mercedes goes through NAEP scores over many years and shows how they went up nicely until 2015, when they stagnated at about 1/3 proficient. She patiently explains that until 2015, scores were going up, not declining as Campbell believes.


Now for Campbell to understand this, she is going to have to read it and think about it.


Will she?


Will she correct her error about 2/3 of US kids in 8th grade being “below grade level”? It is not true.
