With reference to your article (LGBT author hits back at attacks over book for schoolchildren on gender diversity, 3 January), I would like to take the opportunity to clarify for your readers that Ofsted does not formally recognise any specific programmes to support LGBTQ inclusion in schools. As an independent arbiter of education standards, Ofsted is mindful of avoiding suggestions that we endorse or recommend particular educational programmes or resources. From time to time individual inspection reports may make reference to the tools or programmes a school has used, and the impact they have had in the context of that particular school. However, this should not be taken as official recognition or endorsement of those tools and programmes.

Sean Harford

National Director, Education, Ofsted
