David Munro, Inverclyde, proposing immediate withdrawal, said he was facing "a nightmare of assessment" in multi-level classroom teaching. Tom Tracey, his Inverclyde colleague, said the EIS was wrong to be sucked into the "huge whirlpool of Higher Still".
But Larry Flanagan, Glasgow, said that Labour deserved time to consider its position and to respond to EIS criticisms about funding, the time-scale for implementation and arrangements for classroom organisation.
Bob Colman, Highland, said: "Teachers are acutely aware of the need to reform the curriculum in the upper school." David McGinty, Aberdeenshire, said 70 per cent of pupils in the senior school were "not engaging in inclusive or comprehensive education".
George MacBride, education convener, promised to use the moratorium on Higher Still to present the union's concerns to the Education Minister.
