The actual Legislation relating to MS Education for children with SEN (the SEN CoP is 'just' Statutory Guidance) is:
"316 Duty to educate children with special educational needs in mainstream schools
(1)This section applies to a child with special educational needs who should be educated in a school.
(2)If no statement is maintained under section 324 for the child, he must be educated in a mainstream school.
(3)If a statement is maintained under section 324 for the child, he must be educated in a mainstream school unless that is incompatible with—
(a)the wishes of his parent, or
(b)the provision of efficient education for other children.
(4)In this section and section 316A “mainstream school” means any school other than—
(a)a special school, or
(b)an independent school which is not—
(i)a city technology college,
(ii)a city college for the technology of the arts, or
(iii)[F2an Academy].]" Section 316 of the Education Act 1996
This IPSEA guidance illuminates 'incompatible with.....', using case law.
Are you saying that both the LA and yourself agree, but the school disagree? Is this only going to tribunal because you want additional therapies added in? If you didn't, what were the LA planning to do to resolve it?
