Kindergarten services differ from one kindergarten to another, and from public (state) to private ones, and may include initiation in foreign languages (typically English, French or German), introduction in computer studies, dancing, swimming, etc. All kindergartens provide at least one meal or one snack, some having their own kitchens and their own cooks, others opting for dedicated catering services. Many kindergartens (especially the private ones) provide children with transportation to and from kindergarten. Groups typically have 1–2 teachers ("educatori") and 10–15 children (typically more in state kindergartens).
