I’m in my second year of the Diaconate program in Detroit.
Here in Detroit, a Bachelors in not a requirement, but very helpful, as the program has a lot of pre-req’s that are usually handled by an undergrad degree. (I’m kinda SOL anyway because my Engineering degree was somewhat lacking in Philosophy, Psychology and Rhetoric

)
Here is the program I am in

There is also a Master’s level program, but I’ve got 4 small kids at home, so I didn’t really want the extra coursework.
The Archdiocese pays for all the classes, and traditionally (at least here) your parish picks up the cost of books and retreats.
Our first year consists of taking classes while your official application is in process ( which is extensive). It also includes criminal background checks, and psych exams for yourself and your wife.
The application is reviewed in early summer and an applicant is either accepted or rejected.
The second year is called the Aspirancy year. It is a year of discernment. After one completes the Aspirancy, and academically earns the Parish Ministry certificate, the Rite of Candidacy is conducted and the Aspirant becomes a Candidate.
Then is 3 years of classes, practica and service internships.
One is Installed as Reader and then Acolyte during these years.
Finally Ordination.
During all this time ( Aspirancy onward) we have regular Formation days ( one Saturday each month) and 2 Retreats, one with wives, and one without.
