Sorry Starfish about the warnings about the WPPSI...I didn't realize it was already administered. It is certainly possible that the scores will be useful to some extent....please don't kick yourself for not knowing in advance more than your local experts. We are just more used to kids who teach themselves to read at 3 and what that might translate into in terms of unusualness.
Fun Fact - "did you know that IQ scores. Don't measure smartness.....they measure how rare a particular level of smartness is for agemates.
Some kids who teach themselves to read at 3 have a pretty rare level. Other kids who do that have more usual levels and just happened to be early in reading. Others fit the 2e catagory. I'm glad that the WPPSI is already taken because that means that soon you'll have at least half an answer.
Love and more love
