Well, this isn't really the best site to ask that question. However prior to WW1 the Royal Aero Club was responsible for assessing fliers and awarding Aviators Certificates. There is a short summary here

There were several flying schools throughout Britain most notably at Hendon, where the Graham-White company were the largest, and at Brooklands, where Vickers were based. For more details on activity at both in 1911 try searching the Flight archives
