Do the multiple choices of a test question mean the same to different people?
By Minjeong Park
Abstract: Multiple choice questions are widely used in both large scale and classroom assessments. However, educators rarely think about if students with the same ability or skills may have different probabilities to select the options, which may affect their academic performance.

Psychometric investigation of the Ages and Stages Questionnaire: Methodological challenges and potential solutions
By Oscar Olvera
Abstract: The Ages and Stages Questionnaire 3 (ASQ-3) is a widely-used screening tool to identify developmental delays in children aged from 2 to 66 months. In spite of this popularity, very little psychometric research has been done on it due to the intricacies of the data it generates. This study presents 3 methodological challenges prevalent in ASQ-3 data as well as solutions to address them.
