You become a Disney Specialist by graduating from the College of Disney Knowledge. It is basically a correspondence course, and the end of which is an exam that you have to score a certain amount (I think 80%, if I remember correctly) on to pass. Then there are all sorts of continuing educational support from Disney including on-site programs. I think a true Disney Specialist, though, should not only be a CDK graduate, but should have a true passion for Disney. I am a NUT!!! The certificate of graduation is secondary to my love for Disney.
