The purpose of this study was to investigate the effect of test length and sample size in Item Response Theory (IRT) on model-data fit, item parameters and standard error values. For this purpose, small (150, 250, 350, 500, 750) and large (1000, 2000, 3000, 5000) samples were drawn from the research population through stratified random sampling method. Item parameter estimation has been done in these samples in three (10, 20 30 item) different test lengths. The findings were compared in terms of modeldata fit, item parameters, and standart error values.
