Schools are obligated to inform parents of everyday school life and of their child's performance at school. For this reason schools conduct meetings between teachers and parents, parents' evenings (school information for parents), and information events. Most of these events are compulsory for parents. Parents are responsbile for their childs attendance at school. If a child cannot attend (e.g. illness) parents must inform the school. They should also make sure that their child does homework. By taking a regular interest in homework and school projects they can support their child. For persons who are not yet familiar with the Swiss education system there are special information events.
