 The transition to the new system and the Medical Training Application Service (MTAS) have been particularly criticised.In order to implement MMC, all trainees not appointed to specialist registrar posts for 1 August 2007 were required to apply for posts on the new MMC curriculum, with far fewer posts than applicants.However, the application process has had technical problems, and was criticised over the weighting and marking of the applications, with one London training school calling it "unfair and ineffective" in resigning from the process.
