I really enjoyed my conversation with Glenn but I am a bit surprised that the National Job Corps Study did not make it into the article.
Addendum: an exchange between Glenn Thrush and Alan Krueger. As I expected, Glenn argues that the NJCS is too old to be relevant. I would disagree given the stability in program design and operation. Glenn, Alan and I might all agree that we should be doing "rigorous" evaluations of active labor market programs more often that we do.
I would have liked more about the legal angle - I had thought that the courts had made it rather difficult to require general tests like this that are not directly and obviously related to specific skills required on specific jobs.
