Some studies have investigated the association between motor development and cognitive skills. The present study aims to correlate motor development and academic performance in 79 students between 7 to 9 years old from a private school in São Paulo-Brazil. We used the Movement Assessment Battery for Children - Second Edition (MABC-2) to assess the motor development and the results of school report in Portuguese and Mathematics as a measure of academic performance. Pearson\u27s correlation analysis showed a positive association between motor development and cognitive skills, evidencing that students who had better academic performance, also obtained better scores in motor performance. The association between MABC-2 total score and Portuguese grade, for example, obtained a significant correlation of p <0.014. Further studies should be carried out to understand if motor development improve can modulate cognitive skills
