In state-run schools in England, Wales and Northern Ireland (but not in privately run schools), there is a requirement for a daily act of worship that is "wholly or mainly of a Christian character", although non-Christian faith schools are exempt (instead having to have their own form of worship) and sixth-form pupils (in England and Wales) and parents of younger pupils can opt out. Official reports have recommended removing the requirement entirely. The High Court of the United Kingdom has ruled in favour of challenges, brought by pupil families supported by the British Humanist Association, to secondary-level religious studies exam syllabuses that excluded non-religious worldviews.
