The general Teaching Council for Scotland has reacted to teachers' concerns over a "reaccreditation" scheme for experienced staff.
Tony Finn, the council's chief executive, has written to teaching unions urging them to "seek consensus", while acknowledging the issue is a "significant challenge".
The GTCS was asked by the Scottish government in February to develop proposals for a system of accreditation. It was a key part of ministers' plans to establish the council as an organisation fully independent of government.
Mr Finn's letter says that the GTCS is "uncomfortable" with the continued use of the term "re-accreditation".
It "might suggest that teachers should be required to re-engage in the assessment of those basic skills which they acquired on qualification", he wrote.
"We prefer to consider this initiative as an opportunity for teachers to refresh and develop their professional skills".
The Educational Institute of Scotland, which dominates teachers' representation on the GTCS, has previously expressed "serious reservations" about the scheme. NM.
