A Post Leaving Certificate (PLC) (Irish: Cúrsa Iar Ard-Teistiméarachta) is an informal term covering a large range of courses and qualifications run in Ireland for students who have finished their secondary education. The majority of students who enrol on a PLC course are under 23, however mature students are welcome. A Post Leaving Certificate is taken after a student has passed their Leaving Certificate, and is generally a one or two year course. PLC courses are aimed primarily at students who would like to develop vocational or technological skills in order to enter a profession, or go on to higher education.
