I dunno. But they're going there because of the trails, not because "OMG we have to train here". It's just convenient that they can continue their training while following up leads.

I doubt they're going to enrol as students though. They'll be too busy hunting down leads and following up on things. Besides, nothing teaches better than experience and all that jazz.
