Student sued school district, school board, assistant superintendent, and teacher under Title IX and § 1983 for alleged sexual harassment by fellow students while plaintiff was in the sixth grade. The court held, inter alia, that: (1) school officials have qualified immunity because the right to be free from a sexually hostile work environment created by peer-on-peer sexual harassment was not a clearly established right; (2) opportunity for relief under Title IX precluded a suit under § 1983; and (3) liability under Title IX may vest only upon a showing that the district had actual knowledge of the sexual harassment.
