Instructional Design Master's or Graduate Certificate Programs

Hello, I've been working in HR for almost a year now and I'm really interested in transitioning my career into instructional design, as I'm very passionate about teaching and inspiring others. Ideally, I would like to be a corporate trainer, and eventually work freelance. I'm thinking of enrolling in a certificate program at a school that also has a masters program that I could potentially enroll in after. Does anyone have recommendations??

The cert. program I'm primarily interested in right now is Boise State, as their admissions process does not require letters of recommendation (I have been out of school for about 2 years now and my current employer does not know about my interest in transitioning out of general HR work, so I'm hesitant to ask her for a rec). I'm located in San Diego and was looking at SDSU and CSU Fullerton, but they both only offer Fall entry dates (I'm looking to start ASAP). Any suggestions other than Boise?

Also, can anyone tell me the difference between ID and e-Learning? I have seen certificate programs for both at the same institution, but the descriptions sound very similar? birdman
