Abstract

One of the activities to assess test quality is item analysis, which considers the general quality of the test and the quality of each item. The study was completed after tests were collected and run on all samples, and the results served as a guide for future quality improvement of the test. This study aims to analyze the validity, reliability, level of difficulty, discriminating power, and effectiveness of the distractors on Class IX Science questions at junior high school (SMP) Negeri 9 Batanghari. The data analysis technique used is a quantitative descriptive technique. This research was conducted at SMP Negeri 9 Batanghari. Class IX students of SMP Negeri 9 Batanghari were used as research subjects. The population is all class IX students at SMP Negeri 9 Batanghari, totaling 50 students.
