IntroductionThe majority of studies on the HIP IQ attest a heterogeneity of the IQ profile as specific to HIP. However, the samples are recruited in clinical consultations. Thus, it is important to investigate new samples from schools.ObjectivesWe aimed to analyze the index scores of the IQ profile of children without disorders or specific school assistance.MethodsThe WISC-V was conducted and analyzed in 80 healthy children (50 HIP vs. 30 non-HIP), aged 7-to-13 years-old (mean 10y; SD 1.8). All children were recruited in private and public schools in Paris.ResultsAll IQ index scores were significantly higher in the HIP vs. non-HIP. In both groups, the Verbal Comprehension Index was the highest index while the Processing Speed Index was the lowest. There are significantly (p=0.02) more heterogeneous IQ profiles in HIP (64%) vs. non-HIP (47%), with a significantly larger gap between the highest and lowest index (respectively: median = 29.5 vs. 21.5). There was a significant-positive correlation between IQ level in general and the heterogeneity of the profile (r = 0.42; p
