经典测验理论

模拟实验表明，利用GRNN可以以任意精度拟合CTT（经典测验理论）参数统计值和IRT参数值间隐含的非线性关系。

Simulation experiments denote that it is feasible to fit the nonlinear relationship of item parameters between CTT ( Classical Test Theory ) and IRT given any precision .

经典测验理论（CTT）的主要缺点有：对测题难度、区分度及测验信度的估计依赖于被试组，对被试能力的估计依赖于所使用的测验题目，只提供平均测量精度等。

Classical Test Theory ( CTT ) has many defects , namely the estimations of its parameters depend on the subjects , the estimation of ability level depends on the items , and it offers only average precision of estimation .

目前常用的测试质量评估手段经典测验理论具有明显的缺陷，其计算结果会随受试样本的变化而改变。

Classical test theory ( CTT ), the most used approach for test quality evaluation nowadays , has an obvious defect that the computation result fluctuates a lot with the change of the samples tested .
