Traditional tests that assess intelligence require skills and ways of responding that are difficult for individuals with specific clinical conditions such as developmental disorders. Thus, it is necessary to provide tools that enable this evaluation. An internationally used test for evaluating nonverbal intelligence in developmental disorders is the Leiter-R, applied from ages 2 to 20. Three performance measures are provided: Fluid Reasoning, Estimated IQ and Total IQ, by means of subtests of the Visualization and Raciocínio Battery. The objective of this study was to perform the translation, adaptation and to check psychometric parameters of the Visualization and Reasoning Battery of the Leiter-R in pre-school children. The translation and adaptation were performed according to assumptions presented in the guidelines of the International Test Commission by following these steps: translation, examination, adaptation and review of the final version. Participants were 254 children between ages 3 and 6, students of 1st to 3rd Stage of Childhood Education from two public schools in the city of São Paulo. Results of variance analysis showed significant effect of age and grade in performance in all Leiter-R subtests, except Sequential Order. Differences in performance due to the time of schooling were found in the Repeated Patterns subtest in children at age 4 of the 1st Stage and in the Figure-Ground and Form Completion subtests in children at age 5 of the 2nd Stage. ANOVA revealed differences of gender for age 6 in the Paper Folding subtest, with better performance in the feminine group. Patterns of convergence were verified through significant and positive correlations between scores in the Leiter-R with the Columbia Mental Maturity Scale and Raven s Coloured Progressive Matrices. Correlations between test and retest were positive and significant for most subtests. The Spearman-Brown coefficients were around 0.84 and Cronbach's Alpha for age and grade showed values around 0.77 indicating good accuracy of subtests. Thus, the results suggest good adequacy of psychometric parameters of the Leiter-R, fulfilling basic requirements that attest to the quality of the tool.
