This report was designed to reinforce the previously presented service test of tennis by providing some data acquired at the classes in the college. The test consisted of 10 trials of service of tennis, 5 of which served from right side and the other 5 of which served from left side. Each trial was scored twofold: the points for the spatial accuracy of the first bounce (perfect score=4) and the points for the distance of the second bounce (perfect score=4). Thus perfect score of the 10 trials was 80. The second bounce was evaluated in order to take the speed of the service into account. All of the thirty-six female college students, served as subjects, took the test twice. Main results were as follows: 1. The average score for the first and the second test was 11.17 (6.71) and 11.94 (5.64), respectively (SD in parenthesis). 2. The subjects whose scores in the first test were 10 or less gained significantly (ρ<0.05) higher scores in the second test. 3. The Spearman's correlation coefficients by ranks between the scores of the first bounces and those of the sum of the first and the second bounces were 0.96 (ρ<0.01) for the first test and 0.97 (ρ<0.01) for the second test. This result suggested that the accuracy of the service determined the total scores.
