A Bristol-based education consultant has urged teachers to record conversations with Ofsted inspectors after a head took her own life.
Ruth Perry was expecting Caversham Primary School in Reading to be downgraded from "outstanding" to "inadequate" when she died in January.
Anna Ephgrave, who has 30 years teaching experience, says anxiety caused by inspections is "horrendous".
The Department for Education (DfE) said they were a legal requirement.
But Ms Ephgrave said teachers should have more scope to challenge a grading.
Speaking to BBC Bristol, she said schools get less than 24 hours notice before inspectors arrive, creating an atmosphere of constant stress.
