What IS a good part-time program?

Over on my own blog, I've talked a bit about the new part-time program rankings that USNWR is proposing and the new part of this year's questionnaire that asks voters to name up to 15 "good" part-time programs (see here). Setting aside the misnomer--most of the students in the part-time programs work about full-and-a-half-time, between their "day jobs" and studying for law schools--I have to wonder what constitutes a "good" part-time program.

Is it the availability of good teachers for the program? A good selection of classes? Mentoring for the part-time students? The ability to provide the students with some semblance of the extracurricular activities that the full-time students experience? How well the graduates perform? Whether enough of the graduates get plum jobs after graduation?

This question is timely for two reasons: because it's the right question for educational reasons and because other USNWR voters are filling out their ballots now. I'd love to hear your thoughts.
