Applied Psychological Measurement: Volume 46, issue 2, page(s) 571-588

 

This study evaluates the degree to which position effects on two separate low-stakes tests administered to two different samples were moderated by different item (item length, number of response options, mental taxation, and graphic) and examinee (effort, change in effort, and gender) variables. Items exhibited significant negative linear position effects on both tests, with the magnitude of the position effects varying from item to item.

Impact of Both Local Item Dependencies and Cut-Point Locations on Examinee Classifications

Posted: | J. D. Rubright

Educational Measurement: Issues and Practice, 37: 40-45

 

This simulation study demonstrates that the strength of item dependencies and the location of an examination systems’ cut‐points both influence the accuracy (i.e., the sensitivity and specificity) of examinee classifications. Practical implications of these results are discussed in terms of false positive and false negative classifications of test takers.
