This study aims to obtain a mathematics learning outcome measurement tool that meets the quality requirements of the questions at the junior high school level and is developed using a modern test theory approach (Item Response Theory, IRT). This study involved samples of students in grades VII, VIII, and IX at SMP 2 and SMP 5 Samarinda in 2017. Determination of the research sample using simple random sampling technique at the school level. PCM scaling uses non-routine items with polytomous scoring. Data analysis techniques to find out the quality of the items using two ways, namely quantitative and qualitative methods. The results showed that mathematical questions with PCM scaling met the expected quality. The results showed that from 20 questions there were 13 items in the quality category.
