The Postgraduate Diploma in Education (PGDE), also known as a Graduate Diploma of Education (GradDipEd), is a one-year postgraduate course in several places like Australia, New Zealand, the Republic of Ireland, Hong Kong and Singapore for existing bachelor's degree holders leading to become a qualified teacher.
The qualification is normally taught at a university or other higher education institution, though much of the course time is spent on placements in local schools. For example, in the Hong Kong programmes, most school will have lesson time for about 20 weeks, and another 14 weeks (usually taken in 6 weeks for the first semester and 8 weeks for the second semester) for placements.
In the Republic of Ireland, the former Higher Diploma in Education (H.Dip.Ed.) was renamed as the PGDE from 2007 onwards.
The Postgraduate Certificate in Education (PGCE) is the equivalent of the PGDE in England, Wales and Northern Ireland and historically in Scotland. Some universities, for instance Durham University award PGDE on successful completion of 120 University Credit Units (UCU) of a Master of Arts Education course (ie, completing two years). The PGCE is awarded after 60UCUs.
