The first purpose of the present study was to make out the skill tests in volleyball games and examine the reliabilities and objectivities of the tests. Further, the second purpose was to clarify the structure of the group skills in games. Team performance in volleyball games could be classified into two large categories of performance: 1. the performance to get points: A-1: serving A-2: attacking after reception of attacking from service reception by opponent team A-3: attacking after reception of attacking from reception by opponent team after A-2 2. the performance to get side-outs: B-1: attacking after service reception B-2: attacking after reception of attacking from reception by opponent team after B-1 The volleyball skill tests consisted of six individual skills (Serving, Serve reception, Tossing, Spiking, Blocking and Reception) and attacking performance of opponent team. The observed games were the 1988 Spring League of six Intercollegiate Men's Volleyball in Kansai and the performed skills were rated on 30 games, 128 sets with each team and set. These 11 sets which were randomly selected out of them were rated again to investigate the reliabilities of the tests. To investigate the objectivities of the tests, the 11 sets were further rated by another experienced volleyball player. The reliabilities and objectivities of the tests were estimated by using the method of Cramer's V and rates of contingency. To determine the structure of the games, the number of rallies were counted in games. To further examine the structure of the group skills in volleyball games, the frequency of the appearance of composed skill's patterns of the group skills were calculated and investigated. The major results were as follows: 1) It could be inferred that the volleyball skill tests had relatively high reliabilities and objectivities. 2) As the frequency of rallies in volleyball games were calculated, 81.2% of attacking had been performed by the second rally. 3) The frequency of performance formed by only blocking was significantly greater in A-2. The frequency of attacking performed in liaison with blocking, reception, tossing and spiking was also significant and second greatest in A-2; The attacks of these two skill patterns occupied about 77% in A-2. 4) In A-3, the frequency of attacking performed by only blocking was significantly greater and the frequency of attacking followed spike covering was significantly smaller. 5) 91.7% of attacking from service reception (B-1) was performed in liaison with service reception, tossing and spiking. 6) The frequency of attacking performed by only blocking was significantly higher among the composed skill patterns in B-2.
