I think this because some schools have gotten caught up in delays in the ‘course renewal and approval’ process. If their course is not ‘re approved’ in time, they have to opt out of the specific topics that are awaiting approval from USCG. When they get ‘reapproved’ they can teach them again.
I wanted to go to NE maritime last year, and their course was ‘hung up’ in the approval process. So I went to CMTI. Theirs was all set to go.
Last year I was at GMATS. They got a course curriculum submission, approval and had a course in ONE week. So it can be done, but I guess it helps to know high people in low places (or VS/VA)
