Type 2 graduate diplomas:

Are for students also registered in another graduate program at Carleton University.. You may apply for admission to the diploma program at the same time as you apply to another graduate program or after you have been accepted into that program. In both cases you must make a separate application for admission to the Northern Studies diploma program.

Type 3 graduate diplomas:

Are for applicants who do not intend to be registered in another graduate program at Carleton University.

The curriculum for both diplomas is the same.
