The purpose of the study is to develop an electronic basketball chest pass measuring tool that reduces human error while assessing basketball chest pass technique. The research and development approach was used in this study. A total of 31 students were used as research participants on large-scale test. Data analysis in this study is a validity test using an external validity test by correlating the results of the chess pass using the Chest Pass Automatic Board with the results of the conventional chess pass, and the reliability test using Spearman Brown. The results of data analysis obtained a product validity value of 0.9985 and a product reliability value of 0.999. The Chest Pass Automatic Board prototype is valid and reliable for measuring basketball chest pass technique.
