Which IS is good for gifted child

WYmom

Reading ahead of 3 to 4 years of UK peers are very common among my kids' class, I don't think it implies gifted child.  I don't know how those assessments are made, but just won't care too much on such results.  Generally the kids in IS in HK now have higher standard, so I would rather see if my kid is performing upto the standard of her peers in her school.
