Background: The speed world record (WR) performance is an achievement achieved by athletes in the competitive rock-climbing category, where the athlete must complete the climbing route on a standard artificial climbing wall with a height of 15m in the shortest possible time. Purpose: This study aimed to construct and validate an observational instrument to assess technical execution in lead climbing. The instrument developed can be used to assess progress to achieve the important aspects of climbing movement methods. Design/methodology/approach: Importantly, the construction of its validity and reliability was conducted in four stages. The first stage was a literature review on the construction of the observational instrument. In the second stage, the instrument’s construction was established. The content validity coefficient was determined in the third stage using Aiken's V and 7 experts with various qualifications, including the level of understanding, appropriateness of the words, and the relevance of the statement with a grading scale of 0-10. The instrument’s internal validity was calculated using 20 climbers and was quantitatively tested using the product-moment correlation. In the fourth stage, instrument reliability was determined using Cronbach's Alpha reliability test. Results showed that the observational instrument has content validity with optimal internal value as well as satisfactory reliability. Conclusion: Observational instruments were valid and reliable; therefore, they can be used to assess technical execution for novice climbers in lead climbing. It allows instructors, coaches, and teachers to assess the technical execution of novice climbers specifically in lead climbing. © 2021 by authors, all rights reserved.
