Reviewer 3 Report

Comments and Suggestions for Authors

The Chilean study is well-described in terms of its proposal and the results obtained. It was a clever decision to extend the psychometric analysis of the WISC-V by comparing several factorial models, which were not presented in its initial study. Two minor observations I have is regarding the lack of description of the standardization sample used for the analysis. This information is presented in another document (written in Spanish), but it should be mentioned in this paper. For example, the sample was stratified by socioeconomic status, and it was based on municipal schools (286), subsidized private schools (245), and private schools (223). The sample was distributed in seven areas of the country: Arica and Parinacota, Antofagasta, Metropolitan Region, Maule, Biobío, Araucanía, and Los Lagos. The second observation concerns another, and also attractive, line of future research: testing the differentiation hypothesis by ability level (not just by age).
