The purpose of the study was to examine the effect of the multiple true-false test scoring method on the accuracy of estimating ability and difficulty parameters using Partial Credit Model.

To achieve this goal, a multiple true- false mathematics test composed of (35) multiple true-false items was developed and administered to (873) male and female 11th graders of the literary stream and the information technology stream in Irbid First Directorate of Education.

The test was scored by using four different methods that varied in the degree of considering partial knowledge .

By using BIGSTEPS , estimates of individuals' abilities, items difficulty values, standard errors ,and person and item fit statistics were obtained for each scoring method.

Data was re-analyzed after excluding misfitting subjects and items.

The findings of the study indicated that the fourth method in which partial knowledge was most considered is the most accurate method for estimating ability and item difficulty parameters.
