(1) The meeting is voluntary and student-initiated;
(2) There is no sponsorship of the meeting by the school, the government, or its agents or its employees;
(3) Employees or agents of the school or government are present at religious meetings only in a nonparticipatory capacity;
(4) The meeting does not materially and substantially interfere with the orderly conduct of educational activities within the school; and
(5) Non-school persons may not direct, conduct, control, or regularly attend activities of student groups.
