You've now finished your bachelor's and master's degrees and are ready to strive for the highest degree we offer, the doctoral degree. Be ready to put in countless hours studying. Hopefully you have a great group of fellow students with whom you can work on this degree. Help each other out, and have fun while working hard!
Listed in the "Doctoral Degree Course Catalog" below are the courses offered by the University of Geocaching. For each course, you will find the number of credits earned by completing that course and the requirements for completing the course.
In order to earn your doctoral degree, you must earn at least 50 credits. When you have completed at least 50 credits, you may attend graduation (sign the log and claim your find). As part of your graduation requirements, you must fill out your final transcript. Please list in your cache log: your total credits earned, the courses you completed (including credits for each course), your qualification for each course, and how your qualification may be verified for each course (please see my "Note" log on 9/13/2014 for an example of how to log this challenge cache). Your geocaching profile at geocaching.com and either the output from the GSAK macro "FindStatsGen" or your Project Geocaching profile contain enough pieces of information to verify all of the course requirements. You may also verify your requirements in another manner if you like.
You may use the following challenge checker that someone developed for this challenge, but please make sure that you include in your log the output from the checker showing how you qualify for each of the parts of the challenge and your total number of credits.

Each degree recipient is eligible to receive a personalized diploma certifying his/her accomplishment. These are usually sent out electronically at the end of each month.
