Ofsted inspections should be temporarily carried out ungraded to allow the watchdog to focus on reform after the death of headteacher Ruth Perry, a school leaders' union has said.
Inspections were suspended to allow mental health training to be put in place following Mrs Perry's suicide - but will resume on Monday.
Sir Martyn Oliver, who took over as Ofsted boss at the start of the year, said that for a short period only emergency safeguarding visits would take place.
He made the announcement after a coroner concluded an inspection "likely contributed" to Mrs Perry's death in January last year.
She took her own life after Caversham Primary School in Reading was downgraded from "outstanding" to "inadequate".
The watchdog grades on a four-point scale - outstanding; good; requires improvement; inadequate.
School leaders' union NAHT is urging Ofsted to carry out ungraded inspections for an interim period to allow time for the watchdog to work on longer-term reform.
A survey by the union of 1,890 school leaders in September and October found just 3% backed Ofsted's grading system.
Almost two thirds (64%) said inspectors should report their findings in a short summary of strengths and weaknesses.
A report by the union also calls on Ofsted to immediately create a way for school leaders to stop an inspection when the inspector's conduct or practice fails to meet required standards.
Other recommendations include extending the notice schools receive ahead of an inspection to 48 hours.
