The Alf Engen Ski School, named after Alta’s founder and located at the Albion base, has 100 full-time certified instructors. There are adult and children's ski programs, and group classes are limited to eight people. The minimum age for group lessons is four years. Children under four must have private instruction. Instructors follow a nine-level skill progression that makes it easy to choose the right class. Levels 1–3 follow green trails, 4–6 blue trails, and 7–9 black trails. The ski school also teaches deep snow technique to a high standard.
