If you have a good school with a good SENCO and who are prepared to work with you and our child, then great. But if you don't, it's tough. It's totally pot luck. All Individual Pupil Funding (the last rung before statements) has just pulled pulled, despite my son's being agreed to end of 2013 school year due to LEA budget cuts. So there are two strands what the school can and will do and what the LEA could and should do.
I am very luckly that my school is brilliant with dyslexic DS1 in Y6, he can have a scribe and a reader for test, he does a small group with a course called Beat Dyslexia 3 mornings a week that he's in and workjing at 8,30am for. All his homework can be adapted to suit him eg: 100 words required he can do 50, they stress the quality not quantity angle. He also goes to a Madaline Portwood group withing the school run 1 afternoon a week by a TA to helo with dysrpaxia.
What other schools do or dont do in comparrison I have no idea. But in a nutcshell if you get lucky with a school, fantastic, otherwise ou have a shit stained hideous constant battle with the LEA who are forever changing the goalposts, full of people who don't take any ownership or responsibility for anything and take months and months to make any sort of decision, which you can't hang about for whilst your childs education suffers, so you and the school just get the fuck on with it to be frank whilst the LEA pisses about to be honest!
Sorry for the swearing but it warrants it to be honest, it's the great and the good teachers and TA's that make it happen on the ground day to day, regardless of what new pile of crap policy the LEA or G'ovt pontificate about, they live in totally different worlds.
