<p>The paper presents the results of the standardization of the methodology for mental development diagnostic of primary school children Group intellectual test (GIT). The methodology consists of 7 subtests, which are devoted to various aspects of the intelligence. 2512 children studying in the 4th grade (M=9,97 years, SD=0,41), 51,1% boys were recruited for this study. The Cronbach's Alpha consistency score was used to assess the internal consistency of the subtests, which showed good consistency of all elements of the methodology (Cronbach's Alpha=0,9). Exploratory factor analysis confirmed that all 7 subtests add up to one factor explaining 63,4% of the total variance. The general model of the questionnaire was tested using confirmatory factor analysis, which showed good data consistency: SRMR=0,02; CMIN/df=13,09; GFI=0,98; IFI=0,98; CFI=0,98; RMSEA=0,07.</p>
