Thank you. I am open to such idea. I am also pondering whether it is a loop, i.e. he is interested in legos (he is self teaching himself) because his VSI is high, and his VSI is high because he keeps practicing, akin to how some children teach themselves to read.. He was actually tested at 20 months old as part of early start program (he was 2e back then, had since outgrew it with some intervention), and we were told that he was logically very advanced then.

I am still pondering about the re-testing questions, and how to read our results, any insights/advice into this? I don't like exposing him to tests, the kindergarten application process is not fun to go through on its own, but if it gets us some support we can look into it..
