Schools and parents will get NAPLAN results this month, but the agency responsible did not say whether it would still provide an accurate national picture of student performance.
Senior state education officials raised questions on Wednesday about whether results from the new online NAPLAN test, sat by students at a fifth of Australian schools in May, was statistically comparable with results from the pen-and-paper version sat by everyone else.
Mark Scott, the secretary of the New South Wales Department of Education, said the tests would still give parents an insight into their own child's capabilities.
