What DEIS means here
DEIS Rural. This is the rural strand: extra literacy and numeracy support, School Completion Programme access and enhanced capitation. It does not carry reduced class sizes.
Added to DEIS in the 2022 expansion, so its supports are relatively recent.
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.
