Direct Entry courses (also referred to as Non-CAO courses) are college courses where application is made directly to the particular college, rather than through the CAO process.
Some of the many private colleges in Ireland offer accredited Degree programmes, equivalent to those in Universities and Institutes of Technology, which may offer an alternative route to the career of your choice. These are fee paying courses that do not use the competitive 'Points System' to select students.
You can get a list of full-time undergraduate courses on offer in Private colleges using the CAO Wizard on this site. Search using the same criteria used for CAO courses, but look out for courses marked 'Non-CAO' in the results page.
