In 1953 the Miles brothers decided to design and build a prototype jet trainer which would be much less costly than the Jet Provost, then under consideartion for the RAF. The M.100 Student was built as a private venture and, owing to the limited resources of the company, construction took a considerable time. As with many Miles designs the Student included a number of unusual features for its time, but it was May 1957 before it flew and too late to be a contender for the RAF contract. The frame has carried the previous registration G-APLK and RAF test serial XS941.

On static display at the 1974 Hatfield Open Day. The sole example of this Miles design initially intended as a two-seat side by side military trainer, but which lost out to the Jet Provost and, after trials, was never accepted by the RAF in any form. Housed at Glasgow for a time but rarely flew. Re-registered as G-MIOO and moved to Duxford, where it was substantially damaged in a take off accident in 1985. The fuselage survives with the Museum of Berkshire Aviation.

Registered to F.G.Miles Limited at Shoreham (EGKA) and intended as a military jet trainer. That did not happen and consequently this was the only example built. In 1984 it was acquired by Aces High and re-registered G-MIOO. Cancelled as withdrawn in 2009.
