There are several important tests that measure or motor skills in children; however, and taking into account that the intervention should be based on rigorous assessment processes of body movement, in Colombia does not exist any research that shows the validity and reliability of a test that allows assessing children’s motor skills. Objective. The objective of this study was to determine the psychometric properties of the short form from the Bruininks Oseretsky Test of Motor Proficiency (BOT 2) Second Edition. Materials and methods. To get the results an evaluating diagnostic test was performed in 24, apparently healthy, children, both male and female, with ages between 4 and 7 years old, living in the cities of Chia and Bogotá, D.C. The assessment was carried out by three experts, with three different methods; the internal consistency analysis was performed using the Cronbach’s Alpha Coefficient; the reproducibility analysis was established by the Intraclass Correlation Coefficient; for analyzing the concurrent validity the Pearson correlation coefficient was used, considering that α = 0.05. Results. High reliability and validity ranges were obtained for all the tests. Conclusions. The BOT 2 is a valid and reliable test. It can be used in our context to assess and identify children’s motor skills development levels.
