Just a reminder for those interested in such things that Larry Solum is continuing to aggregate data on entry level law school hiring here. Yale and Harvard are way out in front in terms of total hires, though past experience suggests that a few other schools will see their numbers rise as more data comes in.
Interpreting the post-JD experiences of the various individuals, it appears that 34 of the 71 new hires listed have previous full-time teaching experience. It is increasingly clear that VAP, and VAP-like, positions are a highly valuable credential for candidates on the law teaching market. What is less clear to me is whether it is the VAP position itself, or the publications that come out of that extra time, that are making the big difference.
