Well that depends how you look at it All of them are public schools coordinated by one communal Schulbehrde but there are six different Schulen with their own Schulleitung and with one or more compuses You do not have free choice of school but will be assigned by the communal Schulbehrde based on your home address There is also a public music school And there are other publicly supported but private schools such as Montesori Tertiary schools are coordinated by cantonal Behrden  Anyhow I would you thoroughly advice you to dive into the schooling system first if you really intend to take over this part Or then leave it as it and eventually some local will take over this knowldgeintensive part And anyhow it is futile since all necessary information is already publicly available Why reinvent the wheel By the way do not call it high school its very missleading Anyhow the direct trabslation is not advised if at all use the local naming And it is more complex than you probably think if you want to handle all eventualities and specialities  You get the message Thanks
