First of all, I need to explain what Senior Middle School is. In Shanghai, children go to primary school at the age of six. At the age of eleven they go to junior middle school, where they study for four years until they are fifteen. During the nine years, the children receive their compulsory education at school with two mid-term and two final examinations every year. At the end of Year 9, they take the formal examination set by the municipal authority. Then according to the results of this exam and their own wishes, the students have various choices to make: to go to work, or to technical schools, or senior middle schools, where they will study for another three years until they go to university if they succeed in the Entrance Examination. Senior middle schools are selective and are always among the students’ first choices. So in some way, senior middle schools in Shanghai are similar to Key Stages 4 and 5 in the UK.
