These Regulations prescribe the circumstances in which an admission authority may (in addition to the circumstances set out in section 89(5) of the School Standards and Framework Act 1998 (the 1998 Act)) vary the admission arrangements they have determined for a particular school year.

Regulation 3 provides that an admission authority may, without further procedures or approval from the National Assembly, vary the admission number they have determined for any relevant age group where such a variation is necessary to implement approved statutory proposals published under section 28 of the 1998 Act, and a variation of the admission number is necessary to implement those proposals. In those circumstances, the procedures for changing admission arrangements in section 89(5) to (7) of the 1998 Act do not apply.
