Basketball jump shots (JS) are widely regarded as a high-complexity specific motor talent that needs substantial instruction and practice. The goal of this article was to perform a comprehensive evaluation of JS performance among 13 and 14-year-old basketball players in Ho Chi Minh City. The authors employed the scientific methodologies in sports research to develop 06 criteria for measuring JS performance and to identify 07 typical tactics that young basketball players took in games. According to the assessment results, their JS performance was 1.08% on average. Notably, the second and sixth tactics had the highest JS efficiency (1.6%), while the fifth had the lowest (0.59%). More notably, the findings suggested that the JS performance of youth basketball players was highly related to their competition outcomes. It indicated that school teams with a large number of players with good JS abilities were more likely to get high scores, whereas teams with only a few competent JSskilled players appeared to perform poorly.
