Best Graduate Degree/Course for PE work.

Hello,

I am curious if there is a general consensus for which self study course of specific masters degree is best for preparing one for pE work. I am not asking about which helps the most in terms of actually getting a job. Basically say you we given a job hypothetically as a PE associate and wanted to get the best training. I have see a number of self study courses as well as specialized masters degrees. I know this is a little unusual. Any opinion on which of the specialized masters or independent courses would be the top course would be appreciated. Thanks.
