Considering the importance of validity evidence studies when designing psychological instruments, this study intended on verifying the construct validity of reasoning subtests, through convergent evidence and CFA, as part of a battery for giftedness assessment. A Manova was also applied to evaluate sex and grade differences. The sample was composed of 96 students, in which 49 were female, with 6th grade (n=15), 7th grade (n=12), 8th grade (n=49) students and 2nd year (n=20) students from a public school in the state of São Paulo, aged between 10 and 18 (M = 13.4 years, SD = 1.8). The participants answered the Raven Progressive Matrices Test (general scale) and reasoning subtests that belong to the Battery for Giftedness Assessment (BAHA/G). The results from Pearson's correlation indicated convergence as the majority of the factors composed in BAHA/G showed positive and significant correlations with the Raven test factors, and the CFA displayed two latent variables with strong correlations, particularly among their total score (r=.976). With these results, we found the moderate relationship between these instruments. Further studies are recommended on other types of validity evidence of these subtests to confirm its psychometric qualities.
