PREMIUM P1 tests have long been a source of controversy. Education Secretary John Swinney, right, was criticised earlier this year over moves to make them available despite the impact of Covid-19.

It comes after The Herald uncovered significant variation in arrangements for Scottish National Standardised Assessments (SNSAs), with families in some council areas unlikely to be informed that pupils will sit them. Education Secretary John Swinney and his officials came under fire earlier this year following confirmation that the controversial literacy and numeracy tests would remain “available” despite disruption to learning in the wake of Covid-19.
