i left teaching not because of the kids but because of that culture.
you have no idea of the frustration of knowing what is needed, caring about kids and wanting to do the best for them and constantly getting fucked over from on high.
initially you fight thinking you can make them see sense or present it in the right educational terms or legal terms or whatever. eventually you realise they just don't give a fuck what happens behind your classroom door.
that's your problem and there is a total denial that the culture and system in place influences what happens in there and hamstrings what you can do. it is a pretense that the classroom is the world and nothing exists outside of it itms - as if the kids land in your room in a bubble untouched by policy, funding, resources, fucked up behaviour management systems that are failing, sen not being met, etc etc etc.
there is also a total pretense that mixed ability teaching and total inclusion can be achieved without any extra resources or people or information even.
now this was secondary and as i've acknowledged i found it worse here than in another area so it may have been particularly bad here but if i'd have had parents attacking me and blaming me for all of the above as if i had any control over it i dare say i'd have quit a lot sooner than i did and a lot less supposedly unteachable, low ability, sen kids would have had grades a-c in at least one subject on their exam results than subsequently did.
