@yuqiliao Why do we use asribm01
which is on scale 1-5 for Y? Can we not use rrea
and then average it and get achievementLevel?

that's an option! I did that simply to follow the TIMSS paper. In the TIMSS/PIRLS, besides 5 PV, the datasets also provide 5 proficiency levels (such as asribm01
) based on 5 PVs, i thought maybe it is "more correct" to use these 5 proficiency levels. you are right, we could totally do what you said.
