The CAO Handbook 2027 is now available online, giving prospective college applicants a comprehensive guide to the CAO application process, key deadlines, course choices and admission procedures for the 2027 academic year. The handbook is published by the Central Applications Office and is designed to help applicants understand the different stages of applying to higher education in Ireland.
The new handbook confirms that the CAO online application facility opens on 5 November 2026 at 12 noon, with the facility to add or change course choices also opening at that time.
Students planning to apply should take note of several important dates outlined in the handbook.

The handbook also reminds applicants that they are responsible for ensuring their applications are accurate and submitted on time.
