The study saw two inspectors conduct separate short inspections of the same school on the same day. They then came to independent judgements about the effectiveness of the school. This process was completed in 24 primary schools.
In 22 of the 24 inspections, both inspectors agreed on the outcome of the short inspection. In these cases, the inspection was converted to a full two day inspection, which is standard practice where inspectors carrying out short inspections cannot be certain that a school remains “Good”.
Reflecting on the findings in her first monthly commentary, the new Chief Inspector Amanda Spielman said “the study provides a welcome positive view of inspector consistency in the particular context studied”. She described the study as “a first step towards a continuing programme of research” and indicated that future work would also look at the validity of inspection judgements.
