分类一致性是标准参照测验信度研究的重要内容,而在国内的各种资格认证测验和水平考试中却鲜见应用和报告。本文尝试利用分半方法估计分类一致性信度指标。结果表明,在分类一致性信度指标的关键特征上,分半法估计结果与两次施测或同质复本方法的结果是一致的。此种方法对于大规模资格认证羽验来说是可行的,即容易解释和理解,更便于实际操作。

Classification consistency is an important part of the standard reference test reliability study, but in the country a variety of certification tests and level examinations rarely seen in the application and reporting. This article attempts to use the half method to estimate the classification consistency reliability index. The results show that the half-estimated results are in good agreement with the results of two methods of test or homogenous replica on the key features of classification consistency reliability index. This approach is feasible for large-scale qualification testing, which is easy to interpret and understand and easier to implement.
