Post-Leaving Certificate (PLC) courses (Irish: Cúrsa Iar Ard-Teistiméarachta) are a set of courses and qualifications run in Ireland for students who have finished their secondary education. The term refers to post-secondary education courses which are not found within the higher education sector, but the further education sector in Ireland. The majority of students who enrol on a PLC course are under 23, but mature students are also welcome, and increasingly enrolling on such courses. A Post-Leaving Certificate course is taken after a student has passed their Leaving Certificate, and is generally between one and two years in duration. PLC courses are aimed primarily at students who would like to develop vocational or technological skills in order to enter an occupation, or progress to higher education.
