Only 17% of 370 top-rated schools kept their ranking after many years of exemption from oversight by education watchdog Ofsted.
Hundreds of schools in England have been downgraded by Ofsted after being reinspected for the first time in years.
According to the watchdog, only 17% of 370 “outstanding” schools kept their grade when they had a full reinspection in 2021-22.
Ofsted said it had reviewed more than 500 institutions in the last school year that had previously been exempt from regular inspections, because they had been rated as “outstanding”, the highest grading available.
