The RO can request a deferral of a doctor’s revalidation submission date if he or she is not ready to make a recommendation by the original revalidation date. 

Deferral of the revalidation recommendation is a routine, administrative decision which does not have any impact on a trainee’s license to practise. 

The deferral period would usually be between 3 and 12 months but the RO can request more than one deferral if it can be justified to the GMC.
