Those who complete high school can join a polytechnic or other technical college and study for three years, or proceed directly to university and study for four years. Graduates from the polytechnics and colleges can then join the workforce and later obtain a specialised higher diploma qualification after a further one to two years of training, or join the university—usually in the second or third year of their respective course. The higher diploma is accepted by many employers in place of a bachelor's degree and direct or accelerated admission to post-graduate studies is possible in some universities.
