What school system do the Fisther attend after they move?

A chess prodigy, at age 13 he won a game which was dubbed "The Game of the Century". At age 14, he became the youngest ever U.S. Chess Champion, and at 15, he became both the youngest grandmaster (GM) up to that time and the youngest candidate for the World Championship. At age 20, Fischer won the 1963/64 US Championship with 11 wins in 11 games, the only perfect score in the history of the tournament. He won the 1970 Interzonal Tournament by a record 3½-point margin, and won 20 consecutive games, including two unprecedented 6–0 sweeps, in the Candidates Matches. When the first official FIDE rating list was published in July 1971, Fischer was the highest-rated player by a wide margin.
