background:
I am in the process of developing a Computerized Adaptive Testing (CAT) assessment that involves two separate assessment nodes: one node for administering the first item, and another node for administering the second item and all subsequent items. The purpose of separating the assessment into two nodes is to ensure that each participant receives a predetermined first item. After selecting one of the predefined first items, the participant proceeds to the second assessment node to continue with the remaining items.
Issue:
The challenge lies in the fact that these two assessment nodes operate independently in terms of estimating ability (theta) and the standard error of measurement (SEM). As a result, the theta and SEM calculated after the first item are not carried over to the second assessment node. Instead, the second node begins a new estimation process starting from the second item, disregarding the response and estimation from the first item.
Question:
Is there a way to connect these two assessment nodes—starting with the first item node and continuing with the second item node—so that the theta and SEM estimations can be calculated cumulatively, beginning with the response to the first item and continuing through to the subsequent items?
