You don't need to register in person if you are a returning degree or diploma student, or if you want to take classes without entering a degree or diploma program. Register online through Registration or over the phone by calling 414-297-7462. If you are a new student who wants to enter a degree or diploma program, you need to go through the Admissions process. Then register in person at any of MATC's four campuses. The on-campus time you'll need to spend during the MATC admissions and registration process is kept to a minimum.
