Research of item selection strategy in computer rank examination with an adaptive form

Adopting adaptive form in Computer Rank Examination, the examination would be of the higher efficiency, more fair results, and could develop more of the examination function. To successfully achieve the computer rank examination with an adaptive form, the proper item selection strategy is necessary. Researched different item selection strategy in computer rank examination with an adaptive form.
