Please note that the CAO portal opened for registration this week. All sixth years are encouraged to apply for a CAO number; the deadline is 1 February 2024. Students can start to input course choices straight away. Some courses known as restricted courses must be input by the 1 February deadline (these courses usually requiring a portfolio or audition in addition to the Leaving Cert). For most other courses, the deadline for making final changes through CAO is 1 July 2024.
