Schooling in Norway....any advice?

good afternoon, my family are looking to re-locate to Beitostolen eary next year we have an 8 year old (Oliver) and need to find and address schooling baring in mind he doesn't yet speak Norwegian within the Osytre Slidre Kommune? Any advice would be greatly appreciated in terms of enrollment, travel arrangements on offer to and from potential schools and even any special priviledges in terms of language barriers as English his mother tongue as is mine. Many Thanks Maria
