Derbyshire LMC has submitted a motion for the LMCs conference in June setting out concerns about plans that require GPs to give examples of how they have improved their knowledge and practice to claim 50 'credits'.
Derbyshire LMC secretary Dr John Grenville said the system would require a disproportionate effort from appraisers to decide if GPs had claimed too many credits.
'It's quite a burden to decide if someone has been over-generous or under-generous,' he said.
Appraisers had not signed up to this system, Dr Grenville added: 'What they are expected to do has changed.'
The motion adds that revalidation may discriminate against GPs with portfolio careers.
Dr Grenville said appraisers would need in-depth knowledge of each part of a career to judge credit scores.
'They need to know what I'm like in general practice, as an LMC secretary, as a medically qualified tribunal services member and in medico-legal work. If they don't work in those fields, that's hard.'
But RCGP revalidation lead Professor Mike Pringle said appraisers would be trained to take on the extra responsibility. 'I don't think it will add a lot of work,' he said.
As someone with a portfolio career himself, he did not think revalidation would be harder.
Professor Pringle said portfolio GPs would need someone in each part of their career to 'sign them off'.
'The appraiser does not have to second guess. You come with evidence to show them,' said Professor Pringle.
