Nope, I went onto the 1-year FTE course, but got chopped about 9 months in and went over to running a ground test department at BDN for a while. I then moved out into the light-civil world and part-time did a PhD in flight test methods development (which I passed that time, being about 8 years older and cleverer by then, along with having about trebled my flight test time whilst working in the little aeroplane world).
Careerwise, the PhD has done me a lot of good but (a) I'm an aero-engineer who does some TPing, not a career TP, and (b) it took *()**(( years, so is not a quick fix for anything.
