This years SGS results after the change to the 2 stage test have been interesting. I cannot comment on the ethnic diversity, but nevertheless there seems to have a been a considerable change. Previously the test would favour the mathematician. Some of these would be natural maths geniuses, but it also true that a well coached child may well be elevated to a better performance if enough practice is done. Mathematics ability is not necessarily indicated, though for sure a child needs some aptitude.
What the SGS test has done is to remove, at the primary stage, the opportunity for boys who have had their ability substantially coached to thereby compensate for lower abilities in language and inherent intellect. This favours the child who is naturally bright, but also the child who is naturally exposed to extended vocabulary. I would hazard a guess that this skews the results in a quite different direction.
But I don't see how the selection process has changed from previous years - except that it is done on two dates as apposed to one.
Two years ago there was english comprehension (MC), verbal reasoning (MC), writing and maths. The writing and maths were only marked if a certain mark was reached in the multiple choices.viewtopic.php?f=30&t=16587
