What DEIS means here

DEIS Post-primary. This is extra staffing, a Home School Community Liaison coordinator, School Completion Programme access, enhanced capitation, free State exam fees, and eligibility for the HEAR Scheme for reduced-points college entry.

Post-primary DEIS benefits: Free State examination fees for Junior Cycle and Leaving Certificate, Home School Community Liaison (HSCL) coordinator, School Completion Programme, and eligibility for the HEAR Scheme (Higher Education Access Route) offering reserved university places at reduced CAO points across Irish universities.

Worth knowing: several things people associate with DEIS are now available in every school. Schoolbooks are free at primary and post-primary regardless of DEIS status, and since 2025 all primary schools are eligible for the hot school meals programme. What remains specific to DEIS is the staffing — reduced class sizes in Urban Band 1, the Home School Community Liaison coordinator, School Completion Programme access and enhanced capitation.

Band as published in the Department's DEIS list, last revised 2022-10-12.
