There’s been some good writing on Common Core—e.g. by Richard Reinsch on this site and by my ex-colleague Rick Hess in National Affairs. And there’s been a lot of hyperventilation over it, mostly in connection with de facto presidential contender Jeb Bush’s “doubling down” on his support for Common Core: can he really be a conservative? Isn’t Common Core a liberal conspiracy, hatched in D.C. to take over local schools? Etc. What’s been missing is the voice of a true education expert: me.
