Abstract :This study examines the applicability of discrete option multiple choice [DOMC] items in secondary school mathematics. The test included 25 questions, with 10 being traditional multiple-choice and 15 being DOMC items. Data were collected from 725 secondary school students during the second term of the 2020-2021 academic year. Among these students, 491 (68%) were in 7th grade and 234 (32%) were in 8th grade; 391 (54%) were female, and 334 (46%) were male. The findings revealed significant differences between the two item types, especially in high scores, using classical test theory [CTT]. However, item response theory [IRT] analysis showed that the question type did not affect estimations of students\' ability levels, thus reducing errors in extreme values. This suggests that DOMC items do not significantly impact students\' total scores when parameter estimations are performed using IRT instead of CTT. Additionally, some traditional multiple choice [TMC] items were adapted into the DOMC format to test the applicability of various question types in this format.
