Evaluation is needed to define how much the participants' learning outcomes have changed from their beginning abilities to their abilities after completing the educational process. This research examines the items' quality from a quantitative standpoint. The aims of this study are to determine the difficulty index, item discrimination, distractor effectiveness, and reliability of the final semester test for Chemistry Subject Class X MIPA SMAN 1 Wonosegoro, Boyolali Regency. The research was carried out at SMAN 1 Wonosegoro, Boyolali Regency, using a quantitative descriptive technique. This study's population consists of response data from all 212 students in class X MIPA Chemistry throughout 2019/2020, 2018/2019 and 2017/2018 academic years. Documentation techniques are used to collect data. The data was analyzed quantitatively with the ANATES 4.0.9 version.

Item discrimination is acceptable and meets the standards of sufficient, good, and exceptional. The distractor effectiveness was functions and the reliability value in the Academic Year of 2017/2018 was sufficient at 0.45, but it was high at 0.62 and 0.78 in the Academic Year of 2018/2019 and 2019/2020.
