At around age 11–12, depending on which canton in Switzerland the child goes to school in, there "could" be a screening exam to decide how to separate the students for secondary school. Some cantons have a system of examination in the second semester of the final year of primary school, some cantons have an exam in second semester and continuous evaluation in both first and second semesters. In some cases, parents or legal guardians of the child are also asked for their recommendations (see Indicator C below) along with a self-evaluation done by the child. Parents' recommendation in combination with child's self-evaluation is called the third indicator (Indicator C) for evaluating the student, the first being teacher's evaluation (Indicator A), the second the results of tests (Indicator B) held in first semester. The fourth criteria is the final exam that takes place in the middle of the second semester of the final year primary school (usually held before Easter Break).
