%X Item response theory is a review toward the test and item score based on related
assumptions among parameters of the test item which reflecting the answers of the test items
and the capabilities of participants. There are two terms known in IRT, they are dichotomous
and politomus, the scoring through politomus on item response theory approach can be
analyzed with the Partial Credit Model (PCM). This study uses a simulation method with
politomus data (0,1,2,3) and politomus (0,1,2,3,4) with fixed number of examinees and the
items. The number of examinees and items are determined by the simulation method.
Politomus simulation data are generated using the Win-Gen program. Simulations carried
out four times with different number of examinees, ie, N = 600 and N = 500, and the number
of item = 10. Simulation result shows that the number of alternative answers have different
correlations. Therefore, an analysis of the two alternative answers can be used as a basis for
consideration in choosing alternative answers will be used.
