The objectives and approach of this 15-month research program are described. These objectives included 1 evaluation of the performance of adaptive testing strategies under conditions that more reasonably represent the conditions under which the strategies might be applied in live testing, including effects of errors in item parameters on the performance of adaptive testing strategies and comparisons of adaptive testing strategies in live testing 2 evaluation of the utility for adaptive testing of a number of test item formats and response modes that might be used as replacements for the multiple-choice item 3 investigation of the utility of a number of person-fit indices designed to identify lack of fit of individuals to item response theory models and 4 investigation of the potential of several cognitive information-processing types of tasks for computerized adaptive administration. Research approaches and preliminary results are summarized for each objective. Additional research plans currently being implemented under Project NR 150-433 with which this project was combined, are described. Author
