We also calculated the cumulative percentages of the difference between the GAI and the CPI. We focused on children
who had a clear discrepancy (1.5 SDs, which is equivalent to 23 standardized points) between their GAI (higher) and CPI
(lower) scores. The percentage of cases was high in the SLD-typical group (61 cases, 39.4%) and very low in the ID group (4
cases, 5.2%). Having a higher GAI than CPI score thus seems to pinpoint typical profiles in the SLD-typical group, but not in the ID group. It should be noted, however, that not all the children in the SLD-typical group met the criterion for a clear
discrepancy, even when lower discrepancy values were considered (for instance, only 67.1% of them had a difference of 10
points or more between the GAI and CPI scores).
