In an interesting letter to the editor in the latest edition of Education Next, Ben Rarick from the University of Washington questions why so much of the choice debate has focused on schools. If research indicates that teachers matter so much, why not, asks Mr. Rarick, allow parents to choose their child's teacher? Teachers who are highly sought after could demand higher compensation and those with few admirers would be out of luck (and probably out of business). Mr. Rarick admits it's an idea with numerous practical obstacles, but one that is worth some thought. Someone call Cato.
