Fears over data protection and a lack of responses are preventing schools and trusts from publishing information on the diversity of their governors and trustees.
Last year, the government encouraged leaders to collect information on governing boards and make the figures “widely accessible” to make boards “increasingly reflective of the communities they serve”.
New governance guides tailored separately for maintained schools and academy trusts and released this week re-emphasised the push.
A National Governance Association survey in 2021 found 93 per cent of respondents were white. Just 1 per cent were from mixed or multi-ethnic groups, 3 per cent were Asian and 1 per cent were Black.
