CAO 2023 calendar: The important dates for college applications

Timeline for this year’s college application process

May 5th: The CAO change-of-mind facility opened, enabling applicants to amend, or list for the first time, their course choices. Candidates get a statement of application record online in the correspondence section of their CAO account, before the end of May, listing all details supplied by applicants to date. Applicants must inform the CAO immediately if they do not receive this record, or if there are any errors on this form.

June 7th: Leaving Certificate written examinations begin and will continue until late June. On the day of the last Leaving Cert written paper, applicants under 23 who sat the Hpat test in February receive results to enable them to factor these marks into their final consideration of course choices before July 1st CAO deadline.

July 1st (5pm): Final date for any amendments to course choices and order of preference on all CAO applications for entry to college in September 2023. Most current year Leaving Cert applicants make their final course choice decisions/amendments during this “Change of Mind” period in May-June each year. Initial CAO offers during first week of July: The CAO makes about 6,000 offers to mature (over-23) applicants, and to applicants who accepted and then deferred college offers of places in 2022. These offers are made online only at and remain open for about a week. Mature and deferred applicants who may be away from home should ensure any offer in early July is dealt with, as offers lapse if not accepted within the specified time period.

July 22nd (5pm): An exceptional closing date for registered third-level students who wish to drop out of their current college programme and re-apply for a new list of course choices through the CAO (€60 fee).


August 3: More than 4,000 places on courses are offered at 10am on August 3 to applicants presenting further education (FE) awards and to an additional cohort of mature applicants. Applicants for graduate medicine are also offered places in this round. Offers are open until August 9 at 3pm.

August 25: The State Examinations Commission delivers 2023 Leaving Cert results to more than 730 second-level schools, and makes them available through a secure online service at from noon.
