Item analysis is an important part of evaluating student performance because it can identify the extent to which the questions can measure students' abilities accurately and fairly. This research aims to analyse Numeracy Literacy questions for 31 students from Class VIII at one of the Junior High Schools in Bantul, Special Region of Yogyakarta, using interview methods and analysis techniques for levels of difficulty and differences in questions based on gender and overall, with the help of the AnBuSo 8.0 application. The results showed that although the majority of questions were in the "Easy" category and were effective in measuring students' overall abilities, there were differences in the level of difficulty and differential ability of questions between genders, where questions were more effective in differentiating the abilities of male students compared to female students. These findings indicate the need to improve and develop questions to be more fair and equitable in measuring the abilities of students from both gender groups. By taking these differences into account, better question design can improve the accuracy and consistency of evaluations, providing a more accurate picture of students' overall abilities.
