Thank you all for your replies! Grinity - We haven't done any achievement testing. Do you think this is something that we should do now, or wait a little bit? I don't know much about this kind of testing! I have read before that if your child has many 17, 18 or 19 subset scores on the WPPSI, that they would probably get a higher score with the Stanford Binet L-M. Do you have any experience with this test? Is this something we should consider? Thank you again!
I'd argue no on the considering the SB-LM. The SBLM will likely give you some really impressive numbers. Unfortunately, they are on an outdated test last normed in 1972, often available on ebay for private purchase. I really cannot figure out why any practice still uses this. The SBLM uses a different model of intelligence without valid current norms. It can generate big numbers for parents, but has no real purpose otherwise. In my experience, schools have a hard time understanding valid current tests, let alone controversial ones.
The whole point of IQ tests is to compare one child's performance to another's in order to give you a sense of "where is this kid?" (unless looking for LD, etc.). If there are no current norms, you are comparing your child's performance to children from 1972. Needless to say, some changes have happened since then. K is the new 1st grade and much more academic. Vocabulary, different social mores, computers, etc., have changed the cultural and intellectual landscape. What good does a comparison do to kids from the 1970s? How can that help you figure out what educational needs your child has in 2011?
