1.6 General Prerequisites for All GUE Courses
The following are prerequisites for all GUE Courses (any additional and/or course specific course prerequisite, as well as any deviations from the following, will be listed under the appropriate section of the specific course):
- Must submit a completed registration form, medical history, and liability release to GUE Headquarters.
- Must be physically and mentally fit.
- Must hold DAN Master level insurance or equivalent.
- Must be a nonsmoker.

- Must obtain a physician's prior written authorization for the use of prescription drugs, except for birth control, or for a prior medical condition that may pose a risk while diving. A partial list of such conditions may be found on GUE's medical history form; if a student answers in the affirmative to any of these, they must obtain a physician's approval to dive and disclose this to their GUE instructor before the onset of training. Physician approval for a specific condition is valid for one year from the date it is given assuming there are no further changes to the student's medical conditions.
- Must be CPR/First Aid trained (except for DIR Fundamentals).
