Perhaps we also need to challenge the idea that in plenty of cases that if you do not get top marks in Key Stage 4, your life is somehow over.
There are plenty of careers and life opportunities which are great and have real importance and financial earning potential which are not from high academic achievement.
The life you have is not just about what you learn at school, even if employers do look for certain grades for certain jobs. I think this pressure is really part of the problem.
Not only that some kids will struggle at that stage regardless of many holidays they take and are damaged by this mentality. Equally there are kids who sail through it without having to do a minute's revision. Yet they will miss opportunities which could be of benefit to them. Then there are the kids who might be inspired and influenced by education away from the classroom and will look to alternative education pathways beyond school.
I can't speak for anyone else, but my life didn't turn out the way I thought it would from school. I'm glad it didn't. Yet we are heaping all this pressure on kids in increasing amount with the idea that if they don't do X then they will never get Y out of life. The reality is that Z was their life path that they only discover in their mid twenties. Or later. Because 'life' has a funny way of getting in the way.
Sometimes its simply OK not to be a high achiever at school.
Afterall, how much of the stuff you learnt at GSCE do you even remember, let alone use on a daily basis? Its the principles and patterns that you learn that are far more important than the method taught in school in sooo sooo many avenues in life. Teaching a kid to solve a problem isn't necessarily the same as teaching to the curriculum.
Perhaps I benefit from being the first year that went though school in the National Curriculum in that respect. They hated its perscriptiveness and the fact it didn't teach underlying principles and strategies for life and many still used the old methods they had used before for us. I think perhaps in the intervening years this has maybe been lost from teaching in many, many schools.
