الملخص EN

This study aimed at verifying the impact The effect of item respon type item parameter values and it’s accuracy according to Marginal Likelihood Method under three-parameter logistic assumptions.

To answer questions of the study was to generate responses under five ability distributions' were generated according to three parameter logistic model using WINGEN3 program on (50) dichotomous items.

The generated responses were analyzed by BILOG- MG 3 The findings resulted no statistically significant differences at the level of significance (0.05 = a) in the estimation item parameter values (difficulty, discrimination, guessing) for the type of item response function (logistic, normal).

While the results pointed to statistically significant differences at the level of significance (0.05 = a) in the estimation accuracy of item parameter values (difficulty, discrimination, guessing) due to for the type of item response function (logistic, normal)
