A study of the reliability of Ofsted inspections has provided "a welcome positive view of inspector consistency", the chief inspector has said.
Amanda Spielman, who took up her post at Ofsted at the start of this year, added that these findings should provide reassurance about the process of inspection.
Ms Spielman's comments followed the publication this morning of a report into the reliability of Ofsted's short inspections. The report concluded that these inspections are more than 90 per cent reliable.
The study involved sending two inspectors to visit 24 primary schools that had previously been rated “good” by Ofsted. In 22 out of these 24 inspections, the inspectors independently reached the same conclusions about the schools.
This is equivalent to 92 per cent consistency in these inspections.
