But that won't prevent the same pressure being levied until they are 18.
They MUST stay in education or a training programme (though what will happen if they do not has not been tested yet). Whatever course they do MUST include English and/or maths. It will continue to be pushed, no escape, until they leave or achieve a grade C at GCSE - no alternative will be accepted any more.
So... before they can look forward to working they have at least another 2 years of being told to get a GCSE at grade C.... Colleges have no choice - and very little cash to put in place those extra teachers.
I am currently trying to recruit 5 more as we have an unprecedented number of students with D grades. Made worse by the government interfering and increasing the pass grade requirements part way through the specification. That means kids spent most of their time being taught X, only to be told at the last minute they must achieve X+Z. Obviously those who were borderline C grades then failed. And now I have them! Disgruntled, rude and so very, very lacking in self belief.
If OP thinks her kids can't achieve a C grade then I feel very sorry for her and them. The alternatives are being stripped away, so her kids won't be able to access an alternative curriculum and have the government be happy with their achievement. Instead we, those of us who teach them post 16, will be forced to teach them a totally unsuitable, unwarranted certification, ruining their joy in their ability to achieve in their main course and, basically, making them resent us and our colleagues when they should be revelling in their new found skills.
I can't apologise for it, I don't want to do it. I won't apologise if your kid comes home distraught at being forced to attend more maths, I have no choice. I will try to make it as 'doable' as possible. But as your kid's results have a direct impact on the funding my employer receives I am under a lot of pressure to ensure each and every kid achieves - or we all lose our jobs.
So again - don't rail about it being unfair. Don't moan that your kid is being dealt with horribly - do something! Understand what the changes mean. Don't sit back and ask 'ooh what is really happening?' read the links upthread, believe people like myself who are teaching this, then take more action that bemoaning the unfairness of it.
