The strategy has been applied in a simulation study for the comparison of 6 exposure control methods: point Fisher information, Fisher information weighted by likelihood, Kullback-Leiblerweighted by likelihood, maximum information stratification method with blocking, progressive method and proportional method. A plot showing the performance of each selection rule for several maximum,exposure rates is obtained and the whole plot is compared with other rule plots. This study proposes a strategy to conduct a global comparison of two or more selection rules. In a typical study of the relative efficiency of two competing item selection rules in computerized adaptive testing, the common result is that they simultaneously differ in accuracy and security, making,it difficult to reach a conclusion on which is the most appropriate.
