Inspections under the revamped CQC regime drawn up under chief inspector of general practice Professor Steve Field began in October, after pilots of the new system ran throughout the summer.
Practices will be awarded Ofsted-style ratings under the new regime, either 'outstanding', 'good', 'requires improvement' or 'inadequate'. The first ratings are expected within weeks.
Leicester's The Parks Medical Centre appeared to have become the first practice awarded a rating under the scheme, but a CQC spokesman said its rating had been published in error.
'Good' rating awarded
The practice - awarded a 'good' rating in the document published online - was inspected in July during pilots of the revamped inspection process.
Dr Basil Hainsworth, one of two GP partners at the 4,750-patient practice said the rating had not come as a surprise, and was in line with feedback from inspectors.
The experience of being rated had been 'very positive', he told GP.
'I think generally speaking I feel ratings are very important to build public trust in what’s going on. The procedure was very elaborate, very thorough - it took the whole day. The experience was very positive in my practice.'
