This study aims to analyze the quality of test items for a Grade VIII Junior High School (SMP) Science assessment on the topic of food and the human digestive system using the Anates program. A quantitative descriptive approach was employed, with students from class VIII A at SMPN 1 Majalaya, Bandung Regency, serving as the subjects. The research instrument consisted of essay questions developed based on Science Process Skill indicators. The item analysis covered aspects of validity, reliability, difficulty level, and discrimination power. The results indicate that out of the 10 analyzed items, 6 (60%) were valid and 4 (40%) were invalid. The instrument's reliability coefficient was 0.67, classifying it as reliable with a "fairly high" rating. All items fell into the medium difficulty category (100%), demonstrating a proportional distribution of difficulty. The discrimination power of all items was also in the medium category; thus, the test was generally capable of distinguishing between student abilities, although not yet optimally. These findings suggest that while the instrument is generally suitable for use, improvements are still needed for certain items. The study's results are expected to serve as a reference for teachers in enhancing the quality of Science evaluation instruments, making them more accurate and meaningful for the learning process.
