Abstract
This study aims to analyze the construct validity of chemistry test istrument on the school examination at SMAN 3 Tegal by using Rasch modeling in term of contents, subtantive, and consequential aspects. The participants of this study consisted of 193 students of XII grade. The test consists of 34 items presented in multiple choice form which covered the scope of basic chemistry, analytical chemistry, physical chemistry, organic chemistry, and inorganic. The construct validation using Rasch modeling on the school examination of chemistry subject through the R Program Studio application 4.02 version gave the following results: there were 31 items that matched the modeling; (2) 91.71% of the students' responses matched the modeling; (3) There was 1 item that contained DIF. It means that 31 of 34 items on the school examination of chemistry subject at SMAN 3 Tegal meet the costruct validity of contents, subtantive, and consequential aspects.
