Thanks so much for the info. I'm not sure what a ceiling is - are you saying it's the max score one can get? He just got the one score, Standard Score 145 with an age equivalency of 6 years, 2 months. Maybe he just got one score because he only did the Numbers, Letters and Words subtest.
Is this indicative of a high IQ, or are the tests unrelated?
I appreciate your help.
