7.—(1) A head teacher may vary any direction given by him except so as to extend its operative period if he considers that any provision contained therein by virtue of paragraph (a), (e) or (f)(i) of regulation 5 is no longer appropriate for that pupil.
(2) Any such variation shall be by notice in writing, setting out those provisions of the direction which are to be varied and giving brief particulars of the variations and the reasons therefor.
(3) A variation to a direction shall not come into force until at least one month after the date on which notice of variation is given unless the head teacher is satisfied that it is essential in the interests of the pupil or for other educational reasons for it to be brought into force earlier.
(4) Regulation 6 shall apply to a variation of a direction as it applies to a direction.
