Are some school inspectors more lenient than others?

Abstract

School inspections are a common feature of education systems across the world. These involve trained professionals visiting schools and reaching judgements about the quality of education they provide. Yet there is currently little academic research investigating the consistency of school inspections, including how judgements vary across inspectors with different characteristics. We present new empirical evidence on this matter, drawing upon data from more than 30,000 school inspections conducted in England between 2011 and 2019. Male inspectors are found to award slightly more lenient judgements to primary schools than their female counterparts, while permanent Office for Standards in Education, Children’s Services and Skills (Ofsted) employees (Her Majesty’s Inspectors) are found to be harsher than those who inspect schools on a freelance basis (Ofsted Inspectors).
