Background: This research was conducted to evaluate blocking techniques in volleyball clubs with limited technology. The Assessment Instrument is designed to measure the ability of Beginners athletes to perform a series of movements or techniques. Aim: The purpose of this study was to determine the validity and reliability of the block instrument in Volleyball. Block Test for Beginners (VBTB) accuracy in a series of movements will be broken down into phases consisting of measurement indicators. The assessment technique involves observing the athlete’s blocking movements over three repetitions, with the highest score for each indicator recorded. Method: The techniques used in this study to measure validity are face validity and content validity. As for reliability, it is processed using Cronbach’s Alpha. The results obtained from face validity were 9 out of 10 points and were categorized as very feasible. Result: Content validation obtained scores for Phase 1 8.8, Phase 2 7.3, Phase 3 8.2, and Phase 4 9.2 with an overall average of 8.375 and in the feasible category. Reliability after testing the instrument obtained the results of ∑σt 2 of 4.07, a total variance of 7.63, and indicators of 16 items, resulting in a value of 0.498 comparing with the number of samples/athletes as many as 32 people with a significance level of 5% of 0.349, thus it can be concluded that the instrument formed is reliable with the equation r11 ≥ rtable. Conclusion: The developed instrument is valid and reliable for assessing volleyball blocking skills. Copyright (c) the author(s).
