CQC reports for over 6,700 GP practices have been published by the watchdog since it launched its Ofsted-style rating system in October 2014.
Around 88% are rated 'good' or 'outstanding', one in 11 'requires improvement' and just 3% 'inadequate'.
The CQC revisits practices initially rated 'requires improvement' or 'inadequate' within six months of its first findings. It has re-rated over 540 practices so far, with the vast majority demonstrating improvements.
As of the end of February 2017, the CQC announced that all practices registered from October 2014 have been visited at least once by inspectors.
