DD is generally hard working for school, reluctant at home, dyslexic, needing a bit of maths intervention currently, loves writing.
School A. School in our town, so many friends will go there, walking distance. 1700 pupils. Ofsted requires improvement for reading progress and SEN. New ish head. New into a large MAT. Numbers of teachers left in last 2yrs, assume don't like MAT terms, so some issues with staff numbers, recruitment, teacher continuity. Kids taught in form groups. Taking a 'no messing' approach, uniform, talking in corridors etc. Supposedly aiming to become a dyslexia friendly school but at the start of this road. Good range GCSE options and has a sixth form. Many kids go there happily and do just fine.
School B. Half hour bus ride. Very small, 600 pupils. Fewer GCSE options, no sixth form. In a small local MAT with best schools in wider area. Ofsted good. Good reputation for dyslexia, treated as business as usual. I've heard rumours the Sen teacher isn't great. Good teacher CPD. Better teacher continuity, I believe. Because it's smaller they can be chilled about talking in corridors, toilet use etc. Taught in groups that mix across different classes, eg different class in English to maths. More mixing across age groups across school.
We have grammar schools here which will cream the very top.
