An international expert who advises the Scottish government on education took the controversial test for primary one pupils, and told the education committee: "I didn't find all the questions easy."
Professor Andy Hargreaves also warned of a "possibility" that the strategy of testing youngsters as part of efforts to close the attainment gap in schools may not be successful.
He told how Scotland is "at the front edge of the world" with efforts to ensure the large-scale testing of pupils do not bring "negative consequences" for pupils or teachers.
However he said there is a question over whether improvements in education standards brought about by such standardised assessments are "authentic".
