DS 4 1/2 did the WPPSI at the GDC this morning. He hit the ceiling on 3 of the sub tests and it was recommended we'd do follow up with the Standford Binet-LM tomorrow to make sure we get accurate results.

The ceiling issues were all within the VERBAL part of the test.

What can I expect from doing the Stanford Binet? Are the differences USUALLY substantial compared the the WPPSI?

Thank you for your input.
