语言测试效度研究中所需要收集的重要证据是考试所考察的语言能力结构符合相关的语言能力理论模型。本研究以一项校本英语水平考试的效度研究为例，应用结构方程模型中验证性因子分析的方法研究了该考试的效度，并以此展示语言测试效度研究的另外一个视角———通过研究语言考试的因子结构验证考试的效度。本研究的相关结果为该考试的构念效度研究提供了重要证据，同时也为其他语言考试开发机构开展类似的效度研究提供了新的视角和参考。

An important strand of evidence in support of test validity lies in that the internal structure of a language test concurs with the expected theoretical models of language ability． Using the data from a university-based English proficiency test as an example，this study demonstrated how evidence pertaining to factor structure and factorial invariance can be effectively utilized to support the construct validity of a language test． While presenting important empirical evidence as to the construct validity of this test，this study has provided a different perspective and method of test validation for other examination boards．
