I have read that the exiq on the SB5 has a theoretical upper limit of 225 - but nowhere have I seen or heard of anyone actually getting a score much above 160. The SB5 was supposed to have a much higher ceiling than the SB4 but once they developed it and tested it using a group of exceptionally/ profoundly gifted children they found that it in fact depressed scores even more. Then they developed the Exiq for the SB5 to address the ceiling issues - but what I'm wondering is if it has in fact solved the issue - not just in theory. I guess if I have any more dealings in the future with the testing psyc I can ask her the question directly since she has done a huge amount of testing with it.....
