The YMCA in Ireland has existed since 1849 as a voluntary organisation that works with children, young people, families and the community, with particular regard to those who are disadvantaged and disaffected. Underpinned by Christian principles, each YMCA responds to local need and seeks to share and learn from being a part of a national and international movement. YMCA works in over 34 communities, providing services ranging from peace building to vocational training. It has particular expertise in work with families, youth justice, schools, vocational training, outdoor education and health work. All its work is based on the principles of effective non formal education.
