An Investigation of IRT-Based Assembly of the TOEFL Test. TOEFL Technical Report.
Chyn, Susan; And Others
The current study, carried out jointly by Test Development and Statistical Analysis staff at Educational Testing Service investigated the feasibility of the Automated Item Selection (AIS) procedure for the Test of English as a Foreign Language (TOEFL). Item-response theory (IRT)-based statistical specifications were developed. Two TOEFL test forms were assembled using AIS, and statistical and content-related properties were evaluated. The results show that the statistical consistency (parallelism) of the tests assembled using AIS would appear to be superior to the consistency of tests assembled using traditional test-assembly procedures. The results also provided strong evidence that AIS-assembled TOEFL tests can successfully meet the IRT-based specifications. Test Development staff observed visible gains in efficiency in item selection for Sections 1 and 2 and the potential for time gains in Section 3. The implications of AIS for pool management were explored. Twelve figures and eight tables present analysis results. One appendix provides a sample AIS specification for Section 1.
