I wouldn't wish to denegrate her achievements or dedication.
I'd guess that with the dedication she's shown so far, she'll be doing experimental testing in a few years on the big stuff she flies, and will have therefore become an Experimental Test Pilot. Best of luck to her in getting to that point.
Eric Brown didn't graduate from the ETPS long course either, and probably no other current living TP, wherever they trained, will come close to his standing in the profession. What matters ultimately is the skillset, and demonstration of that - not which school you went to and how long you were there.
