In 1983 Scoil Triest Special School received recognition from the Department of Education and Science as a special co-educational School for primary and secondary aged children with multiple-disabilities. The school was founded under the patronage of the Brothers of Charity.  The school operates under the rules of National Schools and depends on the grants and teacher resources provided by the Department of Education and Science.  It operates within the regulations of the Department of Education and Science.  In operating the school the Board of Management must have regard to the resources and funding available.  In March 2012, the school was re-designated as “A school for students with A.S.D. and Mild /Moderate Intellectual Disability who are over 12 years of age”. The school has now grown in capacity to facilitate seventy two students.
