摘要： 标准参照测验是与常模参照测验不同的一种测验，在标准参照测验中，一个人在测验上的分数不是和他人相比较而是和某个已经设定的标准作比较。如果测验是从某功课论域中随机抽样构造而成，则使用者希望知道考生在这份测验上的观测分数与其在该功课论域上的分数（假如已知）的接近程度；如果使用者想根据测验分数对考生作掌握分类，则他们关心这个推断与假设考生论域分数已知时所作推断一致程度有多高。本文对这两个问题的信度估计进行探讨，得到几个有用的估计公式。

Abstract: A criterion-referenced measure is a test that is different from a a norm-referenced measure.In a criterion-referenced measure an examinee’s score is not compared with others,but is compared with a criterion that has been set.If a criterion-referenced measure is constructed by sampling tasks from this domain of tasks,our interest is how closely do the examinee's scores in this measure approximate with the domain scores.If we intend to make mastery classification based on the examinee's scores, our interest is how closely is the agreement between domain and test score mastery classification.In this paper reliability estimation for the two problems stated above is the criterion-referenced tests are discussed,and some estimating formulas were obtained.

Key words: Criterion-referenced tests, Reliability estimation, Domain scores, Mastery decision
