GLASGOW'S director of education accused the Educational Institute of Scotland of jumping the gun before details go before the city's standards and quality subcommittee next week.
"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.
