Ofsted inspectors use subject 'deep dives' to inspect your curriculum. They use them to consider the 'intent, implementation and impact' of your curriculum as part of the 'quality of education' assessment.
See paragraphs 215 to 217 of the School Inspection Handbook for more detail.
Ofsted has emphasised that it does not make judgements on specific subjects, lessons or teachers. Its inspectors use deep dives to help them arrive at an overall 'quality of education' judgement.
