The aim of this study is to examin -from the statistics of the past records- the validity of the present classification measures for the All Japan Trampoline Inter College Championship, which is based on the difficulty score. At present, competition guide by the Federation of International Gymnastics (FIG) is used for the A class, which B and C class have an original Inter College guide. The rate of pass interruption and the correlation between the total score and the difficulty score were examine using the list of Inter College Championships records from 1996 to 1999 (qualifying round of the voluntary routine : 4 years). Results show that in the men's B class, which has a compulsory routine, the rate of pass interruption was extremely high. There were very few competitors in the C class who competed with a high difficulty score like the B class. In the B class, there were competitors who organized their voluntary routine with a difficulty score similar to the C class. In the A class, the correlation between the difficulty score and the total score was high (men r=0.843, p<0.001, women r=0.720,p<0.001) but the Pearson's correlation coefficient decreased in the B class and showed an even lower number in the C class. From now forth, a new cut off point must be found for the B class and the C class by considering the distribution of the statistics. Furthermore, a need to change the competition guide is suggested.
