Oh OK. That is just another name for RE afaik. In many schools they don't have the option of not doing it. DD has to and is quite enjoying it but probably wouldn't have chosen it if there had been a choice.
My DD is in 2nd year I'd GCSE and loves it. I think it's developed her ability to make a reasoned argument, see both sides of an issue, and has helped enormously with essay writing skills for other subjects. Be aware though that they have a lot of in depth discussions about controversial issues such as euthanasia or abortion.
