To support our part-time students, almost all ECT/DMDL/G4L courses are offered on weekday evenings, Monday through Thursday during the fall and spring semesters, either 4:55-6:25pm or 6:45-8:25pm. Classes that students take outside our program may be offered during weekdays or weekends as well. See the NYU registrar's site for current course schedules. Unlike Master's students, Ph.D. students are expected to participate in professional scholarship, for example, attending talks, conferences, etc. which will not always take place in the evenings. It’s rare that ECT/DMDL/G4L courses (except internship) are offered in the summer, although many other NYU classes that can count toward the degree are.
