Before that, children generally go to Kindergarten, with one or two years is required in most cantons. In the Canton of Ticino, an optional, third year is available for three-year-old children. In some German speaking cantons kindergarten and the first one or two years may be combined into a Grundstufe or Basisstufe where they are all taught together in a single class. In French speaking cantons kindergarten is combined into a four-year cycle primaire 1 or cycle 1 which is followed by a four-year cycle primaire 2 or cycle 2 which completes their primary school. The minimum age for primary school is about six years in all cantons but Obwalden, where it is five years and three months. The cantons Thurgau and Nidwalden allow five-year-olds to start primary school in exceptional cases. Primary school continues until grade four, five or six, depending on the school/canton. Any child can take part in school if they choose to, but pupils are separated depending on whether they speak French, German or Italian. 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 criterion 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). Secondary At the end of primary school (or at the beginning of secondary school), pupils are separated (see Indicator C for Fribourg under Primary School) according to their capacities and career-intentions in several (often three) sections for a period of
