Entry requirements vary from course to course and college to college so it is advisable to check college websites for details.
If you don't meet the entry requirements it is worth contacting a course director and asking whether they would consider your application and/or what you can do to improve you application in the future.
For most postgraduate, when institutions list their entry requirements they are referring to your final year results or what you expect to get in your final year - you don't have to have your results to apply.
For the PME (Professional Master of Education), previously known as the HDip in Education, Maynooth University, UCC, UCD and NUI Galway offer places based on your penultimate year results. If you have any questions about postgraduate study have a look at Postgraduate Study come to the Careers Centre Help-Desk to talk to an adviser.
