What DEIS means here

DEIS Urban Band 1. This is the most intensively supported band. Junior classes are capped at 17:1, vertical schools at 19:1 and senior schools at 21:1 — smaller than almost any non-DEIS school in the country.

17:1 junior class size cap. Urban Band 1 primary schools have the lowest pupil-teacher ratio in Ireland: 17:1 in junior classes (infants to 2nd), 19:1 in vertical schools, and 21:1 in senior schools. That is smaller than almost any fee-paying school in the State.

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.
