Hi again, I think that if you like the prospect of the work and want to get a large chunk of clinical exposure, the certification/employment process might be worthwhile. Don't do it if you think you are going to hate it though, that'd just be unpleasant all around. I enjoyed the classes and certification process, and while I wasn't able to get an employed position due to time constraints, some AdComs thought it was interesting and we talked about it during the application cycle. Not sure how much of a help it was, but I did enjoy the experience and the work involved. It definitely couldn't hurt you, but don't feel the need to take on the task if you think you will hate the job.
