Is it possible to use the table in the link to arrive at extended scores if you know your scaled scores (but not raw)? It seems to make sense for the subtests (table 2) but I'm unclear about the composites. Is the left column in table 3 ("sum of scaled scores") referring to the sum of the original scaled scores of the subtests that make up that composite, or the sum of the extended scaled scores derived in table 2? I'm just curious if it is worth it to go back to the neuropsychologist and ask for an addendum to our report.
