In ETB schools, all students are given equal opportunities for enrolment in line with the Education (Admissions to School) Act 2018. Once enrolled, our schools strives to provide all students with equal opportunities to engage with the curriculum and school life. In all aspects of school life all members of our school communities are treated equitably regardless of their race, gender, religion/belief, age, family status, civil status, membership of the Traveller community, sexual orientation, ability or socio-economic status.
Our schools provides a safe physical and social environment that reinforces a sense of belonging to the school community and wider society. We strive to enable every student to realise their full potential regardless of any aspect of their identity or background. Our school promote a fully inclusive education that recognises the plurality of identities, beliefs and values held by students, Parent/ Guardians and staff. We prepare open-minded,culturally sensitive and responsible citizens with a strong sense of shared values.
Students of all religions and beliefs are treated equally. The school environment and activities do not privilege any particular group over another whilst at the same time acknowledging and facilitating students of all religions and beliefs.
