Moving for a school is a major undertaking and quite frustrating if the school doesn't work out. How many grades in the school? How long would it last? Does having the minimum IQ guarantee admission? Can the admission be revoked? Are other parents associated with the school happy? Would the move be costly for the family or other family members?
From the kids whose scores I know and discussions with many parents, there is a strong correlation between VCI and academic achievement. Much of early elementary is noticing patterns in words, things that go together, organizing writing into concepts and themes, taking main concepts and ideas from reading, etc., which relies on verbal reasoning heavily.
However, your son's scores are solid and pretty even for IQ and achievement and excellent. I'd guess most GT schools would fit pretty well, but some local schools will offer great options and others are terrible. It truly depends on the actual options you have and your son and his personality and interests and capacity to learn more than the numbers from the tests. The test results are great and I wouldn't be afraid of a GT school, even with the "lower" VCI.
