The construct validity test was carried out by analyzing data from the discus throwing test results. The data obtained from the test was tested for validity using the SPSS computer program. (b) reliability test to describe the consistency of measurement results. The results of the discus throwing test instrument developed were correlated with the total score and had a validity of 0.790 and 0.790 which was greater than the r table (0.361). Meanwhile, the reliability result is 0.701, which is greater than the r table (0.361).
