(a) A special student-learner certificate shall be effective for a
period not to exceed the length of one school year unless a longer
period is found to be justified by extraordinary circumstances. These
circumstances must be explained in detail at the time of application.
While each such request will be considered on its own merit, it is
anticipated that such authorizations would be limited to occupations
requiring an extended period of specialized training;
(b) No certificate shall authorize employment training beyond the
date of graduation.
(c) No special student-learner certificate may be issued
retroactively.
