Thirty teachers were given “exemptions” by their union to cross the picket line yesterday so they could prepare for an Ofsted inspection.
The watchdog said it would not inspect schools on strike days as the full scale of disruption “might not be known until the day of the strike”.
They also pledged to notify schools the day before strikes if they plan to inspect the day after walkouts.
Heads’ union ASCL had pushed for no inspections at all during strike weeks, but Ofsted said schools can request deferrals as usual.
