Religion, Values and Ethics (RVE) is the name the Welsh Government has given to Religious Education in the Curriculum for Wales.  RVE now sits within the Humanities Area of Learning and Experience (AoLE), along with Geography, History, Business Studies and Social Studies. The RE curriculum at Pen y Dre has evolved in recent years to reflect the ambitions and four purposes of the Curriculum for Wales.

In KS3 pupils discuss and formulate their own responses to a range of 'big questions.’ These questions include, ‘Should animals have rights?’, ‘How was the universe created?’, ‘Is there life after death?’ and ‘Why do good people suffer?’ They will begin to recognise that responses to such questions are complex, as well as often partial and inconclusive. Through the KS3 curriculum pupils develop their understanding of different religious and non-religious worldviews, which helps to prepare them for our rapidly changing and diverse world.

In KS4 some pupils follow the WJEC full course specification. The course covers topics such as relationships, war and peace, medical ethics and discrimination. Pupils sit one exam at the end of Year 10 and one at the end of Year 11, where they are assessed on the skills of knowledge, understanding, analysis and evaluation. Other learners in KS4 study the Agored Cymru ‘Exploring worldviews’ qualification which is equivalent to a ‘B’ grade at GCSE.
