There are no tests or other barriers to admission to Princeton Charter School. Students who live in the Princeton Regional School district have first priority for enrollment. If more students apply than there are spaces available, a random lottery will be used to select applicants. If fewer students apply, applicants may be accepted from other districts (each district pays for its own students). Students enrolled in the school have priority the next year provided the appropriate grade is offered. Younger siblings of enrolled students also have priority, provided they apply to the school when first eligible.
