Admissions is important. Even if you maintain an open admissions policy you still need to have some kind of application for students and some process for acceptance. You will also need a financial aid process. Even now when workshops are funded by particular sources there should be a mechanism that shows that some of the funding went to student tuition. This would tell people how you intend to help students who have trouble.
Counseling is an area that needs some attention.
You might be able to integrate chemical health counseling, etc. with your colleges. Recreation and Student Life is an area that accreditors usually want to know about. Student government, student organizations, programs for students, etc. should be planned in here. Record Keeping is going to be crucial. As I noted when I was there, each place needs to develop a registrar function so that all the workshops that have been provided are documented through normal college means.
