PLC Courses - PLC courses take place in schools, colleges and community education centres. The courses are full-time and last for one to two years. They offer a mixture of practical work, academic work and work experience. They are designed as a step towards skilled employment and, as such, they are closely linked to industry and its needs. Post Leaving Certificate courses adopt an integrated approach, focusing on technical knowledge, core skills and work experience. Almost half of the time spent on these courses is devoted to knowledge and skill training related to employment, with a further quarter spent on relevant work-based experience.
