The Priory Avenue surgery in Caversham was among the first to be placed in special measures after the CQC launched its revamped inspection scheme in late 2014.
Just 67 out of almost 1,700 GP practices rated by CQC inspectors have been handed the lowest possible rating of 'inadequate', with around 84% rated 'good' or 'outstanding'.
The vast majority of inadequate practices have been placed in special measures, with a strict 12-month deadline to show improvement.
GPonline reported last month that the CQC had begun making second visits to check on the progress struggling practices had made since receiving the low rating.
CQC chief inspector of general practice Professor Steve Field said: 'It is clear that the Priory Avenue surgery has made significant improvements since our original inspection when we had serious concerns relating to the safe and effective delivery of services and the leadership of the practice.
'Under a new management team, and with the support of NHS England and the RCGP, the practice has now set out to provide an accessible, safe and clinically effective service, which will improve the experience and outcomes for its patients.'
