But it appears that "all options" doesn't include Smarter Balanced, because Branstad and Buck asked the consortium to make Iowa's "withdrawal ... effective immediately" and to drop the state from its list of members.
Iowa's plan to use a test other than Smarter Balanced isn't a secret; We reported to you a couple months ago that despite its membership in Smarter Balanced, Iowa had opted to stick with its own test for 2015. Education Week's map of states' testing plans shows that while all but 15 belong to Smarter Balanced or PARCC, only half of the states actually plan to use those tests in 2015. Smarter Balanced's map of members still includes Iowa, but presumably that will soon change, leaving SBAC with 21 state members.

Smarter Balanced, however, doesn't see the situation as quite that cut and dried. The consortium is aware that Iowa won't be using its test next year, but would not confirm that it has withdrawn from the group.
"We do not have confirmation of their plans regarding Smarter Balanced membership," spokeswoman Jacqueline King wrote in an email. She noted that states that aren't using the test but would still "like to stay engaged" in the consortium will have the option of being "affiliate members," she said.
