Accountability policy and its negative effects on teachers' working lives and retention is internationally recognised as a problem in education with school evaluation and inspection being a particular issue, particularly in England. Research suggests that the school inspection system Ofsted impacts negatively on the health and well-being of staff and negatively influences teachers' working practices, which can affect teacher retention. This paper examines the findings of a recent English research project entitled 'Beyond Ofsted' (2023) which aimed to gather a wide range of views on both the current inspection system and potential alternatives. The data discussed in this paper is from part of the data collection which was a large-scale survey of teachers and school leaders. One of the findings of the Beyond Ofsted report was that 76% of our survey respondents thought that Ofsted had a negative effect on retention, with 30% considering leaving as a result of their most recent inspection. We found many reasons for this: the overall experience of inspection, the work in preparing for inspection, and many describing the regime as 'toxic and brutal'. We argue that this is a compelling argument for urgent reform.
