In IRT if the model be fitted with the data, parameters of ability can be measured. In this case, parameters of
difficulty (bA) and discrimination parameter (aA) in the form of A and difficulty parameter (bB) and discrimination
parameter (aB) in the form of B can be compared. In addition, with IRT the parameter of ability (TETA) in the form
of A and the parameter of ability in the form of B can be compared. The results showed that the parameter of
discrimination and difficulty in different mentioned states were not significantly different. The measured parameter
of ability in two groups also did not show a significant difference.
