You can calculate a GAI based on extended norms - my daughter's tester did. If they don't want to or don't know how to calculate based on extended norms, ask for the raw scores to be included in the report, and you can do it yourself.
There's nothing in here that tells me that tells me whether the tester stopped when the child's score could get no better or not. But 19 is the highest possible score on a subtest without extended norms, and I see no reason not to assume that your daughter actually did hit a score of 19 on three subtests.
aeh may be able to calculate a GAI for you based on the information you have given so far. This profile looks like one that they should have routinely calculated it.
