The project aimed to address the need for a valid and reliable instrument to measure fundamental motor skills in Indonesian children and adolescents. Source: Motor Competence Assessment (MCA). Size: 680 participants, 19 schools. Key Variables: (a) Stability: Lateral Jumps, Shifting Platforms. (b) Locomotor: Standing Long Jump, 10m Shuttle Run. (c) Manipulative: Ball Kicking Velocity, Ball Throwing Velocity

The MCA instrument proved valid and reliable for measuring motor skills in Indonesia. The EFA identified two main components: locomotor skills and stability, and manipulative motor skills. Mastering basic locomotor and stability skills is crucial before developing manipulative skills that interact with objects. The MCA instrument can effectively evaluate and promote motor skill development in children and adolescents across various contexts, including physical education, sports, and rehabilitation. By understanding motor skill development and using reliable assessment tools like MCA, practitioners can tailor interventions to meet individual needs, promoting overall physical well-being and performance.

The study employed the Motor Competence Assessment (MCA) instrument, which has been developed and validated across different age groups. The assessment was conducted in two trials for each of the six components. The data was then analyzed using exploratory factor analysis (EFA) to assess the validity of the instrument and Cronbach's alpha to determine its reliability.
