In connection with the determination of a maintained school’s admission arrangements for a particular school year, sections 89 and 90 shall, except to the specified extent, apply in relation to the making or abandonment by those arrangements of provision for any permitted form of selection by ability or aptitude as they apply in relation to the making or abandonment by those arrangements of provision for other matters.

In subsection (1) “the specified extent” means the extent to which those admission arrangements would effect an alteration in the provision made by the school’s admission arrangements as respects any such form of selection (whether by introducing, varying or abandoning any such form of selection) which constitutes a prescribed alteration for the purposes of section 28.

Any admission arrangements to which section 101(1) applies (whether authorised by section 100 or section 101) may be varied if (and only if) the arrangements as varied are designed to secure the objectives mentioned in section 101(1)(a) and (b).
