Following up on this post, and once again taking account of faculty changes since the fall 2014 PGR, here's an attempted update of the top (3.5 or higher) programs in ancient philosophy for 2016-17, again by rough "clusters" of peer programs:

Group 1 (1-5)

Cambridge University

Oxford University

Princeton University

Stanford University

Yale University

Group 2 (6-11)

Cornell University

University of Arizona

University of Chicago

University of Pittsburgh

University of Texas, Austin

University of Toronto

(Note:  Berkeley and Notre Dame were close to Group 2 last time.)
