How is residency defined?

In order to attend school in the District, a student must actually reside in NANTUCKET. A student’s primary residence is the place where s/he dwells permanently, not temporarily, and is the place that is the center of his or her domestic, social and civic life. The primary residence of a minor child is presumed to be the legal residence of the parent(s) or guardian(s) who have physical custody of the child.
