POSNER, Circuit Judge.

Harper Elementary School (kindergarten through fifth grade) is a public school in southern Indiana with about 350 students and 30 teachers (including teachers’ aides). Early in 1981 Mary May and two other teachers — all three evangelical Christians— began meeting every Tuesday morning at the school to pray, sing hymns, and discuss the Bible.
