Revalidation is the current system used to check that licenced doctors are fit for the job.
It requires doctors to demonstrate on a regular basis - usually every five years - that they are up-to-date through appraisals with their employer.
Members of the public can give feed-back in patient questionnaires, which are taken into account in these appraisals.
Revalidation started in December 2012 and the majority of licensed doctors are expected to be revalidated by March 2016.
