Elizabeth Maginnis insisted time for Higher Still training and development could be found within the asymmetric week that allows schools half-day closures on Fridays to free teachers from class contact and is unique to the former Lothian authorities.
"We have staff in schools for half a day a week without pupils and it does seem perfectly possible to use these extra half-days. I think we are being extremely generous asking for the extra day," Mrs Maginnis said.
George Rubienski, a secondary depute head who represents teachers on the city's education committee, lodged a strong protest. As a staff development co-ordinator, he said he would find it difficult to identify where the extra time could be found and existing commitments could start to unravel.
"I do not believe we are better prepared than other authorities," Mr Rubienski said.
