This page contains links to 185 psychology Ph.D. programs rank-ordered in quality according to the most recent study conducted by the National Research Council (with "quality scores" taken from a summary of the NRC report published by the APS Observer).
The Canadian Psychological Association Graduate Guide is a good source of information on graduate study in Canada, and John Krantz also maintains an extensive international list of Psychology Departments.
Note to Students: The rankings below should be considered no more than a rough approximation. You would be well advised to consult as many faculty members as possible for feedback on your top school choices before applying to graduate school. Admission to graduate school is competitive, so apply to as many schools as possible; have your friends, family, and academic advisors look over your application materials; and if you receive letters of rejection, don't lose your sense of humor!
