Hi kidzmom3,
I'm not an expert.

I know a little. I went back to school too.
There are some variances from state to state and even institutions have their own policy on conversions.
The top things I think to consider are:
1.) How long ago did your DH get his associates degree?
There is a time limit for applying credits towards another degree. In VA last time I checked I think it was 10 years for all credits except science related ones. That may have changed and may be different in the state that you live.
2.) Were the credits for semesters or quarters?
I believe most community colleges have converted to semesters here in VA. If you DH has semester credits the conversion should be pretty cut and dry. If it's quarters it may be he'll need to apply 2 courses for one.

It's hard to say.
3.) What major is your DH interested in?
That could be the deciding factor in where he'll need to enroll. It might be a good idea to pick up a college/university book that describes the courses/programs. Also talk to some of the professors in the discipline he chooses.
Something that would help in the process of converting credits is to have a college book (from the community college he attended) that describes the courses he took. That may come in handy when talking to administrators. It makes the process a lot easier than going by the title of the class alone. They are looking for some key words to determine if the objectives have been met.
I just saw where Cindy B mentioned the CLEP. That's a great option. And Saffron had some good ideas too.
Good luck! I think it's a great idea.
