Abstract  ?with?the?development?of?the?theory?and?practice?of?cognitive?diagnostic?computerized? adaptive?testing?(CD-CAT),?more?and?more?attention?has?being?paid?to?dual-objective?CD-CAT.? Item?selection?criteria?is?the?core?of?CAT.?First, by?untangling?the?researches?of?item?selection? strategy?of?CD-CAT?and?dual-objective?CD-CAT,?these item selection methods were divided into several kinds. Then, their?characteristics,?relations?and?performance were introduced and? commented in detail.?At last,?based?on?researches about cognitive?diagnostic?models?and?the development?of?CAT?practice,?several future research directions were concluded. It?is necessary ?to?strengthen?the?research?of?item?selection?strategy under the?general?cognitive?models?and more?complex?test?conditions. Developing?indexes represent items and test characteristic of dual-objective?diagnostic?testing is also very important. It is meaningful to strengthening the?research?of?non-parametric?item?selective?method?and application?of?CD-CAT.
Keywords computerized?adaptive?testing,?cognitive?diagnostic?model,?item?selective?strategy,?measurement?accuracy,?non-statistical?constraints
