"Q: What is a Master Instructor?
A: The Master Instructor designation is a national accreditation that may be earned by aviation educators and is based on a system of advanced professional standards as well as peer review. The designation is granted by NAFI and serves a dual purpose. First, it identifies and publicly recognizes those “Teachers of Flight” who are demonstrating an ongoing commitment to excellence, professional growth, and service to the aviation community. Second, it sets professional standards to which all aviation educators can aspire.
The designation requires a rigorous process of continuing professional activity and, like a flight instructor certificate, must be renewed biennially. To promote continuous involvement in the aviation community, designees must remain active and renew their designations every 24-calendar months. Unlike one-time awards for past achievements (i.e., a “Gold Seal” flight instructor certificate or “Flight Instructor of the Year”), the Master Instructor designation acknowledges an individual’s continuing professional growth and involvement in a broad spectrum of aviation endeavors."
