Hmm. I'm no help on that one; my ds took the WPPSI at 5y5m.
Can I ask another question? You don't have to answer, I'm just curious. Why are you switching out of Montessori? We had a great Montessori Early Childhood experience (ds did a toddler program from 2-3, and Early Childhood from 4-5). We switched out mainly so he could start K with his classmates, and Montessori past K just wasn't an option for us.
I know a lot of gifted children, especially gifted preschoolers, do well in a Montessori program because it's less structured.
Just curious!
