In Hong Kong, students all attend school through secondary school at which time they take the Hong Kong Diploma of Secondary Education Exams (HKDS). The score the students receive on these exams determines their future track. A minimum level of 3 must be scored on all parts of the exam in order to continue on to the university. A minimum level of 2 must be scored on 5 parts of the exam in order to continue on to a community type college or a vocational school. At the age of 15, students may choose to pursue a full-time vocational program and receive a Diploma in Vocational Education rather than an academic diploma.
It should be noted that Hong Kong has a 3.4% unemployment rate.
