Several key topics are conspicuously absent from sex and relationships education.

It is 50 years since the Sexual Offences Act partially decriminalised male homosexual acts and started what has been a long and slow journey towards equality on its way.

Next year’s LGBT History Month theme, ‘PSHE, Citizenship and Law’, was chosen to help schools mark this anniversary and to draw attention to the fact that PSHE (personal, social, health and economic education), despite being an important subject and channel for raising issues of equality in the classroom, is not an examined subject and so lacks the credibility of other areas of the National Curriculum.
