I'm at Hampshire College in Amherst, MA. We have (or had until recently) a JanTerm alt. process class. It's four hours a day for two and a half weeks, and covers Pt/Pd and cyanotype. I took it last year, and TAed it this year. Unfortunately this year was the last JanTerm, so the future of the class is unknown. We do have plenty of opportunities for people to study alt. processes independently. This semester, there was one student who did an independent study in Pt/Pd, and there's a senior who just finished her thesis project which included gum, cyanotype, salted paper, and a few others.
