The facts

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.
