More than 7,500 UK doctors have been revalidated in the first six months of the new system of checks.
Revalidation, which was introduced in December, means that 235,000 licensed doctors must prove to the General Medical Council (GMC) that they are fit to practice.
Doctors are expected to bring information about their practice as well as patient evaluations and proof they are keeping up to date, to an annual appraisal.
In the first six months, 7,663 doctors had their recommendation for revalidation approved by the GMC. They will continue to have annual checks over the next five years, after which they will be due to be revalidated again.
Niall Dickson the GMC's Chief Executive and Registrar said: “The success of the first six months is a significant achievement for the doctors who have revalidated and the organisations they work for.
“We hope the doctors have found it useful to reflect on their practice and to get feedback for both patients and colleagues.”
By the end of this year the GMC expects to confirm that up to 30,000 UK doctors have revalidated. The aim is for the vast majority of doctors to go through the process by 2016.
