Starting in 1967, Plante was one of the instructors at "École moderne de hockey," a summer hockey school for young players. His reputation as a teacher spread, and he traveled to Sweden in 1972 at the invitation of the Swedish Hockey Federation, teaching the top goaltenders in the country and their coaches and trainers. During his first and second retirements, Plante also coached goaltenders and consulted for several NHL teams, including the Oakland Seals, Philadelphia Flyers, Montreal Canadiens and St. Louis Blues.
