Welcome, KIcsscDC!
If you don't mind, clarify for me again what scores you are posting. Are these the sums of scaled scores contributing to the GAI and FSIQ? Or are these the sums of raw scores (not clear what you meant by "did include raw scores"). How many subtest scores might be affected by use of extended norms? At this child's age, it would apply only to 19s, and would typically be recommended only if both subtests in the same cluster were 19s (so both Si and Vo, or both MR and FW; given that you only report GAI and FSIQ, it appears the VSI is not available). If I am assuming correctly, it looks like you had 4 19s and an 18 in the GAI? Age is less relevant to the lookup tables if you already have scaled scores.
The summed scaled scores cannot show up on the extended norms, since you need extended scaled scores to do so. If what you have are scaled scores, there should be no individual scores higher than 19 (if no extended norms). If what you have is raw scores, than there might be some that are higher than that.
With a recent evaluation report, I am surprised you do not have any composite standard scores or equivalent (e.g., percentiles). There should be some interpretive narrative that explains the GAI and FSIQ findings. What kind of descriptive language is included in the report? That might help in identifying what your data actually represents.
