The population of the study was junior and senior high school students and the sample of the study was 1.547 junior high school students and 1.528 senior high school students. The results of the item difficulty index analysis on SPM are not in accordance with the order of difficulty level items. The results of the discrimination index analysis on SPM shows that there are 39 to 41 items with excellent categories. The results of the analysis of the effectiveness of the distractors on SPM shows that there are 42 to 45 items that had effective distracters. The overall results of the analysis of the construct reliability on the SPM are reliable and can be trusted as a test tool.
