Hudd - I don't distrust all HT's, the HT at DD's secondary is wonderful, and runs an excelent school that benefits and progresses all it's puils, from the furthest behind to the furthest ahead. However, I know throgh experience that not all HT's are like that, and there are quite a few out there that would rather spend money meant for SEN pupils on tarting up the outside of the school to attract more MC parents, and ignoring the SEN dc until they either leave Y6 (massively behind where they should be) or are transferred to other schools with better HT's.
So many people (that can drive) have pulled their SEN dc out of this primary, but those who rely on public transport have no choice as there are no other local schools with spaces, they are all inaccessible by bus. So the richer SEN dc get moved, the poorer SEN dc are stuck stagnating. WIth no help.
