There has been some lively and interesting discussion on the subject of where to do a PhD on Wieland Willker's TC list. The message that started it all was one from someone at the Moody Bible Institute (here).
I describe my own view of the British situtation (here) and Bart Ehrman explains for us the ethos at the University of North Carolina at Chapel Hill, initially responding to the suggestion of Malcolm Robertson that "I would not recommend any state/secular university esp and particularly the University of Chicago or the University of North Carolina at Chapel Hill, North Carolina USA."
The whole correspondence is worth perusing, but I think that Ehrman's exchange with Tommy Wasserman perhaps highlights an area where approaches to TC are diverging most significantly. The messages are: Ehrman, Wasserman, Ehrman's reponse.
The messages particularly raise the question as to what are the most important skills and competencies for a textual critic to have.
In addition to the issues raised in that thread I want to raise a few more questions that are relevant to choice of a venue for a PhD:
(1) To what extent is it important to study in a confessional environment? The ideal learning environment may vary from person to person and may vary through the stages of life. All education models are imperfect and we are often looking for the least bad one. Confessional environments can sometimes create people who want to escape—they think the grass is greener elsewhere. If you've been trained in a non-confessional environment you are aware that it often isn't.
(2) To what extent is the supervisor the person who should be helping an evangelical student think through matters in an evangelical way? In some settings it might be that an non/anti-evangelical supervisor alongside strong personal intellectual support from a local evangelical thinker might be a better route than simply to rely on an evangelical supervisor to get it right for you.
(3) People need to assess the relative importance of the institution and the supervisor since supervisors may move (or die or get ill or even get promoted into administration). If you go to an institution just for the supervisor, what would your experience be like if that supervisor were no longer available? If they only have one specialist in NT or OT then you may be in a difficult situation.
