The quantitative approach and instrument development process were carried out through the stages of item preparation based on literature review and theoretical indicators, validation by experts, and field testing of 50 participants.</p> <p><strong>Main Findings: </strong>The knowledge instrument has high quality, obtained as much as 9 data showing a fit for the Rasch model, such as MNSQ infit and outfit values ranging from 0.84 to 1.25. and positive point measure correlations. Instrument reliability shows infit and outfit results that are still within the ideal tolerance range, obtained sequentially the person reliability values of knowledge, attitude, and behavior of 0.50, 0.76 and 0.75. So that the instrument is suitable for accurate and consistent measurement.</p> <p><strong>Novelty/Originality of this study: </strong>this study provides innovation in the energy literacy measurement literature (knowledge, attitude, and behavior) with an in-depth evaluation of item performance and respondent ability distribution using empirical and applicable methods for the development of evidence-based and Rasch model-based assessment instruments.</p> Inda Hasanah Bimastari Muhamad Yusup Kistiono Kistiono Copyright (c) 2025 Inda Hasanah Bimastari, Muhamad Yusup, Kistiono Kistiono https://creativecommons.org/licenses/by/4.0 2025-08-04 2025-08-04 6 3 153 162 10.37251/isej.v6i3.2025
