This study aims to see the ability of dynamic balance elementary school students when walking on the board. Instruments were given to 156 elementary school students from various schools. There are four factors described in dynamic balance instruments that are classified namely; 1) walk forward across the board with both hands stretched, 2) walk sideways past the board, 3) walk forward, hands over the board over the board, and 4) walk forward across the board with both hands folded in front of the chest (alms). Four criteria for student success (Good, Enough, Poor, and Not Good) are determined by the cluster analysis methodology. The results of the study show that the dynamic balance of elementary school children is in the Poor criteria. To see the ability of dynamic balance, it is better for children to be given the opportunity to do the exercises on the board so that it will improve their dynamic balance.
