"We are not saying the whole city should do this as of next week. It is a pilot to establish what works and what does not," Ken Corsar said. "But there is a case for standardised tests at key points so that we have an accurate picture of each child, each school and the value added I would have thought the EIS would have supported that."
Mr Corsar said a consultation with heads and class teachers revealed backing for new tests, provided they did not add to workload. Teachers confirmed the current 5-14 tests were "useful but limited".
Standardised tests would focus on core skills in literacy, numeracy, technology and science but would not narrow the curriculum. Glasgow retained a broad view of educational attainment.
