Hi! Welcome~ this is a good place to find folks with kids whose 'level of giftedness' or 'log' are super high, which is what is indicated by the numbers you have there.
A simple congrats to your ds would not suffice, as I am sure you already know your child is a challenge to parent!
Sorry to hear preschool did not work out, sometimes if it is just a play oriented situation with a broad range of ages, it can work ok even for a highly-gifted child. But often there is such a different level of play, language and interest that a child like this does not fit and finds it very boring.
My daughter also got pretty bored in preschool at 3.5 so I lobbied to have her in K the next year. We had the wppsi done and that was really helpful to be able to show the scores to the director. Gave them something concrete to point to when other 'pushy' parents come around asking for the same exceptions

-- they needed this piece of paper even though in her own words the director said my dd 'is obviously highly verbally gifted'.
Are there other issues you are trying to sort out for your child at this point? Questions from the report, etc.?
Best of luck finding the info you need!
