I'm a tutor, so I would say this
, but:
Why try to make exams tutor proof? There's no such thing as tutor proof. Exams test knowledge and skill, which are learned.
Tutor-proofing's counter intuitive. No state school child will benefit from it. For the reasons reallytired lists so clearly, a state school child is likely to be at a big disadvantage against prep school children. Pace of work is far slower in state school, classes are larger, disruptive children are included in mainstream education, to the detriment of the quiet ones trying to learn. Tutoring evens the playing field somewhat.
Everything we do in life is learned. Everything. From learning to talk, walk, sit on a potty and eat with spoons, to gross and fine motor skills, we learn by imitation and practise. Instinct or innate ability is a tiny part of it all. And why prize innate ability over hard work? Hard working average pupils may do better than brainy laid back ones, long term.
No one says to sports or music prodigies: now, to make this fair, we want you to do no physical exercise or violin practise for the next two years, then we'll see who's the fastest/best able to pick up a tune by ear. It's accepted that talents are nurtured and developed via practise. Why not intellect?
Preps do get children ready for 11 and 13+ - that's what parents are paying for. Tutors fill in the gap in education for state school children. Parents who can't afford a tutor can buy or borrow books and do the practise at home. No one is excluded as a result of tutoring, except the few children who are bright and overlooked both at school and at home. G&T provision should be made for them by a school's SENCO. If I were to campaign for anything to level the field, it would be this. Give a leg up to the bright children whose parents don't give a toss.
'Cramming' in Yr 4 or 5 is not too late. It could be called 'upping the pace and preparing' or 'aiming hard for something you want'. Children don't wilt under a small amount of well-managed pressure. They thrive. They love to be stretched and see their work improve. They are not delicate little creatures who must be allowed to develop without intervention. Positive intervention at appropriate times in a child's life is what makes the difference.
