School attendance is not compulsory in Finland. Homeschooling is legal and possible.
The municipality is responsible for supervising home-schooled pupils to make sure they are following the national curriculum. Study materials, remedial teaching or meals are not provided but healthcare is.
It would be advantageous to home-school your child in a group. If that is not possible to do locally, there exists a non-chartered online school that arranges meetups: https://feeniks-koulu.fi/wp_feeniks/
