多點計分之標準化轉換，有利於異質試題間之比較，劉湘川（2003）據以提出語意問題之標準化多點計分順序理論。多點計分之規格化轉換，具備常用二點計分既有一致之型式，劉湘川、簡茂發（2006）據以提出認知試題之規格化多點計分順序理論，本文兼顧兩種轉換之優點，提出標準規格化多點計分順序理論，藉以可充分有效分析受試者關於任意二點與多點計分測驗中所有異質試題間之關聯順序結構，以利於教學診斷評量。

Standardization scoring for polytomous response testing can be used to compare the ordering relation of any tow heterogeneous items. Therefore, Liu（2003）proposed the ordering theory for standardized polytomous response testing. Normalization scoring for polytomous response testing has the same type as the well known dichotomous response testing. Thus, Liu & Chien（2006）proposed the ordering theory for normalization polytomous response testing. To consider two kinds of above advantages, an improved ordering theory for polytomous response testing based on standardization-normalization scoring is proposed. This paper also shows that the proposed polytomous ordering coefficients can be applied to analyze the ordering relationships of any heterogeneous dichotomous items or heterogeneous polytomous items.
