My IQ in second grade (when school was considering skipping me) was 126. In sixth grade we reached no ceiling at 150. Most school psychs don't like to give a cognitive again if they have one after the age of 8 because they almost always get the same results and feel like they've wasted their time. The ones I know do acknowledge that IQ is less consistent for people of lower socio-economic status.
I did wonder what would have happened for the author of the article if an adult, parent or teacher, were advocating for another test instead of the student.
