Hi Tiggy
My ds got in without private tuition. There are about 3,000 children in each year in LEA state primary and 300 grammar school places. The grammar school does not have a catchment system and you do not have to live in the LEA to sit the test. One of the schools is 0.5 miles from the LEA border so many of the children who sit the test do not live within the LEA border as the neighbouring LEA has no grammar schools. The Head has said that about 10% of those who get in are from independent preps.
So although there are 10% grammar schools places in the LEA, in reality I would estimate that there are only about 5% of children from state primary within the LEA getting a place. I think this is fair because it is not the fault of the children in the neighbouring LEA that there are no grammars within their borders.
The maths 11plus contains only KS2 level questions, so as long as a parent has helped with maths at home throughout primary school, their child should be able to pass the maths. I would not consider that an unfair advantage, but just something a parent should do even if their child is not sitting the 11plus.
There is no familiarisation with VR at school, so parents would need to go through the question types at home so that the child doesn't waste time in the exam trying to make sense of the question type. But any adult who is literate would be able to do this from free internet downloads. The rest of VR ability is based on a child having a wide vocabulary (provided by parents talking to their child, reading to them, playing scrabble) and being able to code break (puzzle books and logic problems throughout primary years). We also did the Usborne guide to trees, dogs, flowers, the seashore etc when we were out on walks so that ds could answer the odd one out type questions.
I do not consider any of that some secret form of tutoring; I just consider it being a parent who contributes to their child's education. It is an effort, and was tiring as we did more stuff than usual in year 5 in the run up to the 11plus, but I do not see why the average working class parent cannot do this.
