“The school has been highly successful in creating a positive, caring and inclusive ethos and provides outstanding care, support and guidance for all pupils.  A culture of high expectation and respect for others permeates all of its work.  This has a significant impact on pupils’ wellbeing and the progress they make in their learning and personal development”  ESTYN 2017.

We maintain the highest expectations of all our students and endeavour to meet their intellectual, social and physical needs and assist them to be better equipped to adapt to the changing needs of modern society.  We believe that effective learning cannot be conducted in isolation if it is to be of benefit to the student and society; hence our determination to seek ways of enriching the quality of students’ learning experience by looking upon the wider community as a curriculum resource.
