Entry into higher education institutions is normally done through the CAO. In this way, students wishing to enter university apply to the CAO rather than the individual university. Places in courses are usually awarded based on results in the Leaving Certificate Examination or any international equivalent. Each university has a minimum entry requirement, usually requiring a pass grade in either English or Irish, as well as maths. Some also require a pass grade in a modern continental European language (French, German, Spanish or Italian). Each individual course has further entry requirements, for example, science courses usually require a certain grade in one or two sciences. The student must also achieve the number of points required for the course under the points system. However, universities also have systems in place for accepting mature students, and students who have successfully completed a Post Leaving Certificate or Further Education course.
