The aim of this study was to determine the validity and reliability of Badminton Reactive Agility Tests System (BRATS) to measure changes of direction speed (CODS) and reactive agility (RA) performance. Next, the effectiveness and strength of BRATS were measured through questionnaires and Methodological Triangulation. The researcher adapted the quantitative approach through descriptive analysis and statistical test using parametric test analysis in this research. The population of the study involves 55 male badminton players under 15 years old and their coaches in Skudai district, Johor Bahru. Findings of this research revealed that the validity and reliability of BRATS are high. BRATS obtained a high value in Methodological Triangulation, thus making it an effective tool. In conclusion, BRATS is an instrument that are capable of assessing badminton as a whole based on CODS and RA aspects. Detailed concepts of badminton players are implemented in BRATS to ensure that lessons can be evaluated holistically. The implication of this study is to produce BRATS that are able to assess badminton players' CODS and RA performances.
