英文摘要：

To be treated equally is the dream of every one. However, the drawback to the evaluation model of college English hierarchical teaching system deprives some students of the dream. The problem lies in the lack of vertical scaling. In other words, the raw scores of multi-level English tests tailored to the ability of each test-taker are not vertically scaled, which leads to both injustice and inequality among students. In order to compare scores of ability-based tests and realize justice and equality, this paper introduces vertical scaling at the beginning, then analyses the nature of the drawback to the present evaluation model, and finally describes a method of creating vertical scale for reference.
