“Notable researchers” can prove anything. If “end-of-course tests ... discriminate against girls” then, by the same token, continuous assessment must discriminate against boys. At least “big bang” exams mean less non-stop pressure and more chance of enjoying a social life (“What has Gove got against girls?”, Letters, 28 June). The way to deal with these “robust equality impact assessments” is to repeal the laws that require them and save teachers’ time and nerves. As for sport - how many sports are mixed or could be in practice? All schools should run sports teams and all participation should be voluntary, ensuring the greatest happiness of the greatest possible number. If boys and girls prefer different sports, no one has the right to interfere.
