Typically, 19 is the top scaled score for each subtest. The report says that it maybe appropriate to consider extended norms for some 18s (not sure when this applies).
Did your psychologist give you the raw subtest scores? If he/she did then you can use the report to figure out how far beyond 19 your kid goes.

I don't have the raw scores. Is it common for parents to ask for them?
