Weingarten's decision is probably not really a spur-of-the-moment one. It's been bolstered by an increasing anti-testing sentiment within the union. In 2012, the AFT consequently passed a resolution opposing many uses of tests and began a media campaign to the same end. Last summer, it issued a report on overtesting.
There is a political element here, too: Factions within the AFT deeply critical of testing have gained power within the union, electing a president to the Chicago Teachers Union who subsequently staged a strike in the Windy City over issues of teacher evaluation.
Whatever Weingarten's new stance may bring for the national conversation about teacher evaluations, it is certainly not going to turn down the heat on this hugely controversial topic.
