摘　　要：理论上探讨认知诊断测验编制的原则问题,指出在给定属性及其层级的条件下,测验蓝图中包含可达矩阵当且仅当知识状态与理想反应模式一一对应,并讨论可达矩阵在认知诊断测验的重要应用及相应理论.A principle of constructing cognitively diagnostic testing is discussed theoretically in this paper.A sufficient and necessary condition that guarantees to build a bijection mapping between knowledge states and ideal response patterns is given.This condition is that test blueprint contains the reachability matrix as a sub-matrix.Some possible important applications of the result are collected or proposed,and some further topics are listed in the end of the paper.
