In this paper I first divide the group of total scores of TOEIC-IP tests that students at Oyama Kosen gained from
2011 to 2014 into three, that is, high score group, middle score group, and low score group. Then, in each score group I
calculate a score difference between the average score of the Listening Test and that of the Reading Test. It is found that
the score difference of the middle score group is always larger than those of the other two groups, which I claim
suggests that students who are thought to belong to the middle score class show more and faster improvement in their
listening skills than in their reading skills.
