Education secretary Fiona Hyslop faced concerns over a low uptake of its proposed new baccalaureate qualification.
Opposition parties also claimed the award, which combines a number of exams together, was crowding the school curriculum. Details of the new qualification were set out by Ms Hyslop, but she later faced a grilling in Parliament on the issue while launching the government`s new science strategy.
"At a time of swingeing cuts to secondary school staffing and where there`s already major curriculum change under way, why is the curriculum to be made more crowded by this award?" Labour`s Rhona Brankin asked.
