As a certified NIST Proctor I can provide NIST flight exams for Basic Proficiency and for Advance Proficiency. These exams are for serious (requires a FAA UAS Pilot License) UAS pilots that want to obtain an APSA accredited UAS Flight certificate and, once passing your flight exam, be registered with APSA.

My training was conducted by NIST and certified by APSA which specifically follows NIST protocols.
