So what would you call the many people, working worldwide, performing competent test flying, usually qualified to do so by their respective governments or authorities, but who haven't graduated from a TP School?
FAA, CAA and even SETP/SFTE all have mechanisms by which these people can be formally called "Test Pilot" or "FTE", it seems a bit churlish to ignore that.
Maybe we could use "graduate test pilot" and "non-graduate test pilot" if it's really necessary to use different terminology?
