What law school(s) are you looking into applying to?
For me selecting potential schools will be based on career/family issues. At the moment I am living and working in Northern Virginia, as such I would likely blanket the part-time programs in the DC area: Georgetown (major reach), George Washington (very expensive), George Mason (more affordable with in-state tuition), American (very expensive), Catholic (very expensive), and UDC (very low ranked, but even out of city tuition is less than in-state at Mason).
The internal argument that I have is the role a JD would play in my expected career path, and what it would be worth in price. I suspect that if I managed to somehow get Georgetown to let me in the door (unlikely, I know) I think that I would be willing to pay the hefty sticker price. Sticker at GW, American, or Catholic I am not so sure about (and to make matters worse, it appears these programs are not very generous with PT students). The more affordable schools Mason & UDC do not look to be overly punishing from a financial stand point, although I am bothered by the five nights a week that 1Ls need to attend as PT students at Mason.
Actually if one of the local programs offered something like the weekend PT program that Hamline has, I would be interested, but it currently does not exist and I am not holding my breath for it to happen in the near future. I have actually considered applying to Hamline and flying up each weekend. Of course, this is insane, but I have bee traveling up to Cambridge off and on for weekly courses for my Masters degree program at the Harvard Extension School.
For work and family reasons I my consider moving to Connecticut, should this happen my options would likely change to UConn and Quinnipiac.
Sorry for the long winded answer to a simple question.
