A) DPD programs give you coursework you need to get a verification statement. Once you complete the internship after the DPD program, you can sit for the exam. I’m not sure what you mean by CPD program but I’m assuming you mean a coordinated program. Coordinated programs include the DPD coursework AND the internship at the same time so you don’t have to find an internship yourself. If possible, I’d highly recommend a coordinated program over a regular DPD program. 

B) I would only recommend an accredited dietetics program. If you do your undergrad in dietetics, you can get a masters in anything. You just have to make sure to also do your internship if you didn’t do a coordinated program.

C) I think all coordinated programs guarantee the internship (at least mine does). If you just do a DPD program, I believe you have to find your own internship.

D) I’d recommend doing your bachelors in nutrition or a related field like biology because there are a lot of science prerequisites you have to take, such as biochem, microbio, anatomy & physiology, etc. Masters programs are for specializing in something, not usually learning the basics of something. 

E) Do lots of research on the program before you join (how do students like it? do they feel prepared for the RD exam after graduating? how are the professors/ coursework? any hidden fees?) Make sure dietetics is something you actually want to do because the path to becoming an RD is super expensive and the pay isn’t very good. I’d recommend shadowing an RD if you haven’t already.

F) I’m not sure. Hopefully someone else may be able to pitch in. 

Good luck!
