Can PROC IRT be used for a scoring run? If I ran a calibration on a large sample with an item bank, and then stored those item parameters, can I then apply those item parameters to another sample? Essentially, this is using PROC IRT with fixed item parameters so that I can estimate person ability scores using the known item characteristics.
I have searched the documentation, but cannot find a way to fix item parameters (even though I can in other procedures, like CALIS and MIXED).
Here is a link to the PROC IRT documentation.
Use the OUTMODEL= option to create a SAS data set that contains the parameter estimates for the model.
Then use the INMODEL(SCORE)= option in a separate call to score a new set of data..
The doc for the INMODEL= option has the details.
