No person who is not a member of the Inspectorate may conduct an inspection of a school in Wales, or act as a member of an inspection team for such a school, unless he has, in the opinion of the Chief Inspector, satisfactorily completed a course of training provided by, or complying with arrangements approved by, the Chief Inspector.

Where the Chief Inspector provides such training he may charge such fees as are reasonable for the purpose of recovering the whole, or part, of the cost of providing it.

Sub-paragraph (1) does not apply in such circumstances as may be specified, either generally or in relation to a particular case or class of case, by the Chief Inspector.
