INTRODUCTION: The development of motor skills influences the capacity of the child to interact with the environment. Thus, several instruments have been created for their assessment. OBJECTIVE: To evaluate the internal consistency, reproducibility, and agreement level of age band 1 of the Movement Assessment Battery for Children - 2 in a preschool group. PATIENTS AND METHOD: Assessment study of diagnostic tests with 29 preschoolers, selected by convenience, enrollments in an educational ins titution in Bucaramanga city, Colombia. For the inter-evaluators reproducibility assessment, three evaluators watched each video independently. In the intra-evaluator reproducibility assessment, each evaluator watched the same video on two different occasions. The internal consistency, the intra- and inter-evaluator reproducibility, and the agreement level were determined using Cronbach's alpha co efficient, the Intraclass Correlation Coefficient (ICC), and the Bland and Altman limits of agreement method, respectively. RESULTS: Internal consistency of the total test for each of the three evaluators was higher than 0.60. Very good reliability was found for all items, domains, and total score of age band 1 of MABC-2 (ICC > 0.85), as well as good limits of agreement. CONCLUSIONS: age band 1 of MABC-2 Spanish version is an instrument with adequate reliability psychometric properties that can be used for the motor skills development evaluation in preschoolers.
