I am glad that you have received some additional useful information from local resources. I have also found that the kinds of strengths your child exhibits on the WISC are less-easily supported in conventional schools (in North America, as well), as the kind of divergent-creative problem-solving at which he excels is not really offered much scope (or even required at all) until the post-secondary/university level, in most cases.
He is blessed to have perceptive and caring parents who appreciate him as he is.
