May we put a team together & register outside the school, having the team made up of students from the school? May the coach be a parent or does it have to be a teacher from that school?

Any adult can be a coach (teacher, parent, administrator, previous competitor, counselor, engineer, local businessman, dentist, shop owner, rock hound, etc,). The only requirement is students must be from the same school and the principal must verify that the competitors are members of that school.
