Given item parameter estimates, you can do subject scoring (i.e., computing scores for subjects). Refer to Example 5 of PROC IRT documentation: Subject Scoring.</P> Thu, 15 Sep 2016 20:36:24 GMT https://communities.sas.com/t5/SAS-Procedures/PROC-IRT-estimate-latent-traits-with-KNOWN-item-parameters/m-p/298799#M60353 PatrickYang 2016-09-15T20:36:24Z
