Here, its not required that you attend an ITP to interpret, but an ITP will certainly put me in the right direction. My main hesitation with attending an ITP is, aside from Gallaudet, there's ITPs that award associates degree. I don't feel its worth my time to go for another associates degree, especially after how hard I worked for the one I just got. I'm not ruling out attending an ITP, but distance and money are also hindering factors.
The thing is it's NOT about the piece of paper (ie the degree) that you get - it's the SKILLS and KNOWLEDGE you get in the programs... that you happen to get an AD at the end of it is "interesting" but not the main "point" of taking an ITP.
As a Hoh/Deaf person myself, here's my honest opinion on the matter:
If you SERIOUSLY want to become an interpreter, then you need to make it "worth your time" to take the appropriate courses and programs that will give you not only the proper skills you need, but also (perhaps more importantly) it also gives you "street cred" in the Deaf and interpreting communities. The "It's just not worth my time to go for this degree" regardless of how you mean it, comes across as if you are saying "I don't want to take the time to do this properly, I just want to be an interpreter" while at the same time you're also saying that you don't feel you have the SKILLS and comfort level to DO interpreting --- which is exactly what the ITP programs are designed to do for you! (and put you in contact with a number of very important people, groups, and agencies along the way as well).
The bottom line - if ASL/English interpreting is really what you want to do - then you need to reframe how you see the ITP ... instead of focusing on the paper at the end, focus on the process and education it provides for you ... both of which WILL help form you into a better, more skilled, more confident and more RESPECTED ASL/English interpreter!
If you you still working towards a Bach. Degree in order to meet the 2012 standards, consider looking into something that will include a number of pychology or linguistis courses as part of the Degree as both would be very valuable while working towards (and once you become) an interpreter.
Education and knowledge are NEVER a waste ... especially if you are looking to work in a field in which you are attempting to become part of a different cultural, social and linguistic group.
The more time you spend learning, practicing and becoming involved in the Hoh/Deaf and ASL communities in a "supported manner" (ie as a student being guided by instructors/teachers/profs etc who are highly skilled and respecited in the ASl/Deaf community/communities)
Hope that helps!
