Ghana has a free education 6-year primary school education system beginning at age six, and, under the educational reforms implemented in 1988 and reformed in 2007, they pass on to a 3-year junior high school system. At the end of the third year of junior high, there is a mandatory "Basic Education Certificate Examination". Those continuing must complete the 4-year senior high school programme (which has been changed to three years) and take an admission exam to enter any university or tertiary programme. The Ghanaian education system from nursery school up to an undergraduate degree level takes 20 years.
