Virtually all major (and most minor) denominations, seminaries, and judicatories require psychological assessment as part of the process of vetting candidates for ordination. The theory is that we have learned so much from the social sciences that it behooves us to employ their insights in doing the various good things that several posts have articulated. It might, for example, assist in identifying a predatory personality or a psychopathic one.
Usually, denominations require a full panoply of psychometrics coupled with actual interviews with therapists. Some tests are little better than the quiz in Parade magazine to see what you like and don't like. Others are geared toward assessing various degrees of psychopathology.
In my work with ordinations in my group, we have used the psychological assessment to guide us in asking more pointed and penetrating questions of candidates. For example, a person with a depressive tendency might be asked what spiritual, physical, social, and medical steps he takes to mitigate some of the effects of the depression. We have also used the results for exploring boundary issues, guilt, anger, etc. in the context of pastoral practice.
In your case . . . be afraid . . . be very afraid. From your posts on the PB, I have already assembled quite a dossier on you to forward to DTS. And, which presbytery were you going with again?
