All persons and students reporting aboard the Advanced Org Vessel or to a Registrar who can sell Advanced Courses, must after enrolment and before any issue of materials pass a full and complete Security Check.

Persons leaving the AO vessel or an Org giving Advanced Courses must be given a Security Check to make sure that they have no copies of materials and have actually attained their grades.

This includes Sea Org vessels where Advanced materials have been used and in this case includes all Non Scientology personnel signing on or departing from the vessel.

There are no exceptions.

Persons who have a history of carelessness with materials or bad or suppressive group connections are debarred from all Advanced Courses unless given a Board of Investigation which clears their record BEYOND ALL DOUBT.
