Exemptions from minimum entry requirements:

Entry to a level 8 degree at Maynooth University requires the applicant to present certain Leaving Certificate (or equivalent) marks in Irish, English and in the case of some degrees - a third language. 
 
If you are seeking an exemption from minimum entry requirements such as Irish (ROI applicants only) or a third language, you must apply to the NUI for an official exemption. 

CAO webpage regarding exemptions.

NB: A Department of Education and Science exemption will not suffice; it must be an NUI exemption. 

Visit the NUI website for application.
