Initial CAO offers during first week of July: The CAO makes more than 6,000 offers to mature (over-23) applicants, and to applicants who accepted and then deferred places in 2016. These offers are made by post and online on cao.ie, and remain open for 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 a week.
