Hi all,

I am sending this message to you all to ask two simple question regarding
IRT based test reliability.

1. What index do you use in calculating IRT based reliability?

2. How to model the reliability in CAT?

if you have any paper related to this topic, could you please let me know?

Please feel free to add your comment.
