http://www.legislation.gov.uk/anaw/2018/2/section/51/notesExplanatory Notes to Additional Learning Needs and Education Tribunal (Wales) Act 2018Education and Public Services Group of the Welsh GovernmentenKing's Printer of Acts of Parliament2018-01-29 2 24 January 2018 Chapter 3 – Supplementary Functions 127 Section 51 requires that where a child of compulsory school age with ALN should be educated in a school, the local authority must ensure that the child is educated in a mainstream maintained school, unless any of the circumstances set out in subsection (2) apply. These exceptions recognise that it might sometimes be appropriate to educate a child with ALN elsewhere. However, the exception regarding parental wishes does not require the local authority to secure the child’s education otherwise than in a mainstream maintained school (subsection (4)). Also, the requirement on the local authority in this subsection does not prevent a child from being educated at an approved non-maintained special school in England or an independent school, if it is not meeting the cost of that education (subsection (5)).
