It really depends what sort of accreditation you're talking about. For example, in language studies you can test into a language competency certification that most people see as being equal to a minor degree. There are computer science certifications, though in my opinion they don't hold as much weight as either a degree or experience itself.

What field or specialty are we talking here? Many fields do have alternative accreditation for people with experiences from outside the classroom.
