The Common Core State Standards Initiative (CCSSI) is a bit like the underdog candidate who wins the election when few think it possible. "Now what?" is the question facing the surprised victor. With an initial agreement for the Common Core State Standards to be developed, and visible progress toward their development and promulgation, what will happen to those standards and the new assessments meant to be aligned with them? There are many ways to think about "now what" or "what next." One way is to seek lessons from a previous effort that has some similarities to CCSSI. The National Assessment of Educational Progress (NAEP) and its National Assessment Governing Board (NAGB) are an obvious place to look. The fact that some are suggesting that the CCSSI and associated assessments might be assigned, long term, to NAGB to run or oversee makes this an important, as well as obvious, place to look. This paper describes what the Common Core State Standards Initiative can learn from the National Assessment Governing Board.
