The "Master" designation is awarded by the the
Flight Instructor community, either by the National Association of Flight Instructors, or by the Master Instructor Continuing Education Program. Requirements of the two organizations vary slightly, but in
general they both state that a Master Instructor is one who, in the previous two years:
1. Has provided at least 250 hours of teaching;
2. Has provided 30 hours of community service to the aviation community;
3. Has spent at least 30 hours creating media material, such as magazine articles, books, webcasts;
4. Has completed at least 30 hours of of continuing education:
5. Has participated in at least 30 hours of aviation activities such as fly-ins or other aviation gatherings.
One other difference between the two designation is that the Gold Seal designation is good for life.
Once awarded, the requirements need never be met again. The Master designation, on the other hand, is only good for two years. To maintain the distinction, a flight instructor must reapply and meet the
same requirements every 24 months.
