Children's participation in physical activity is a leading health indicator to combat obesity and sedentary lifestyles. The challenge to battle this problem is placed in the hands of early childhood educators. However, there is little evidence that early childhood educators have the skills and knowledge to design and implement appropriate movement practices for young children. The purpose of this study was to assess the effectiveness of a movement programme implemented by classroom teachers. Participants were 33 preschoolers. The BOT-2 test was used to assess children's motor skills. Results showed that improvement in motor proficiency was observed in both the control (p?=?0.02) and experimental (p?= 0.001) groups. However, the improvement observed in the experimental group was significantly greater than the control group (p?=?0.04). Acceptability of the intervention questionnaire responded to by teachers showed that the intervention was easy to implement and beneficial to the children.
