Who has ditched ALEC so far?
A major component of the American Legislative Exchange Council’s agenda to transfer the public’s resources to a few private hands revolves around privatizing our public school systems. From model bills that sanction “Virtual Public Schools ” run by for-profit companies to subsidizing private school vouchers  with taxpayer money, ALEC places corporate profits above children’s needs.
Perhaps this is why the National Board for Professional Teaching Standards (NBPTS), the national certifying body for teachers in the United States and an organization that is ostensibly dedicated to serving children’s educational needs, announced  that they are severing ties with ALEC:
Given recent events, the new NBPTS President and CEO decided to discontinue engagement with ALEC. As a result, NBPTS terminated its membership as an Education Task Force Member of ALEC effective April 18, 2012, and also withdrew from participating in the upcoming ALEC conference....The decision to participate in ALEC had been made by previous NBPTS leadership.

NBPTS is a non-profit organization, but they take positions  on many aspects of education policy, including teacher-certification regulations. Before their departure, the organization sat on ALEC’s Education Task Force , which, as the Center for Media and Democracy reports , boasts private-sector members such as the James Madison Institute of Florida and the Pioneer Institute of Massachusetts, both members of the Koch-funded State Policy Network.
ALEC is too toxic even for some for-profit education companies. Last week, Kaplan  announced that they are declining to renew their ALEC membership.
