All consultants (other than a locum consultant appointment) must be on the specialist register of the General Medical Council (GMC). To be eligible to apply for specialist registration with the GMC, doctors must have successfully completed a GMC-approved training programme and been granted one of the following certificates:
- Certificate of Completion of Training (CCT)
- Certificate confirming Eligibility for Specialist Registration (CESR)
Doctors who have not completed a full GMC-approved training programme and wish to have their training, qualifications and experience assessed for eligibility for entry onto the specialist register must make an application under The General and Specialist Medical Practice Order for a CESR. It is not possible to hold specialist registration without also holding full registration.
