The group has written to Education Secretary Bridget Phillipson, calling on her to intervene and delay the rollout of the plans.
In a joint letter, the group said Ofsted had “failed to learn the lessons” from the death of Mrs Perry, who took her own life in 2023 following an Ofsted inspection. A coroner ruled that the inspection contributed to her death.
“The proven life-threatening risks associated with a grades-based schools accountability system, based on public shaming and the fear of high stakes consequences, have not changed,” they added.
Announcing the expansion of a new system for improving schools, which will use the report card inspections, Phillipson said: “Every child deserves a brilliant education – and that means a system that’s relentlessly focused on strong accountability that puts children first.”
Under the new system, inspectors will use a five-point grading scale to mark schools across several different areas:
These categories will be graded as either “exceptional”, “strong standard”, “expected standard”, “needs attention” or “urgent improvement”.
Report cards will also include sections on whether safeguarding standards have been met or not, what it is like to be a pupil at the school, what the next steps are for the school, and details of the inspection itself.
Ofsted said it would also bring in a new monitoring system, to allow schools to be reinspected on areas that need improvement more quickly after those improvements are made.
