Distance Learning?

There are quite a few distance Tecnology programs that are quite excellent at adminstering the same educational objectives of a on-site program. That said, YOU have to be motivated to complete the work, but I think this hold true for any. Where the differences lie, are where you get you clinical training. On-site programs are able to provide instruction in a more standardized and consistant format. If you go distant ed, then your clinical training will be solely based on what vets/ vet techs you work with teach you. Good clinic= good training, not so great clinic= not so great training.
I myself prefer on-site programs. But if you can get some recommendations from the school or OP about a good clinic to work in, then you should do okay. You will be required to work under a vet while in the program. You will be given objectives from the program that you will have to complete but the exact nature of the completion (ie quality) is subjective.

I would choose a distance program based on
a) has a schedule I can work with
b) long standing history of established, ACCREDITED, program
c) National licensing exam pass rate

(probably more but I cant think of anything else right now. PM me if you have specific questions)
