The output automatically displays the models´ parameters, slope and difficulty/threshould, but doesn´t display the latent trait parameter, which is the most interest when setting one IRT model.</P> Wed, 16 Sep 2015 13:23:49 GMT https://communities.sas.com/t5/Statistical-Procedures/Latent-trait-theta-using-PROC-IRT/m-p/225826#M11949 Gladston 2015-09-16T13:23:49Z https://communities.sas.com/t5/Statistical-Procedures/Latent-trait-theta-using-PROC-IRT/m-p/225938#M11955 <P>You essentially want to score the data set.
