This study developed and validated Echoes of Iriga: A Localized Literature-Based Supplementary Material in English 7 for Grade 7 learners of San Juan Integrated School, Iriga City, School Year 2025–2026. It addressed the need for culturally relevant, context-based, and learner-centered instructional resources that connect English learning with Irigueño heritage, community experiences, and local identity. The study was anchored on Culturally Responsive Teaching Theory, Schema Theory, Language and Culture Interdependence Theory, the researcher’s Peripheral Participation and Engagement Theory, and the Input–Process–Output model. Using a Research and Development design guided by the ADDIE Model, the study involved 51 Grade 7 learners selected through complete enumeration and 9 subject experts selected through purposive sampling. Data were gathered through a researcher-made questionnaire, an LRMDS validation checklist, and qualitative feedback forms, and were analyzed using mean, grand mean, and Likert scale interpretation. The developed material was based on three localized sources: Iriga: The Travails of a City’s Historic Odyssey, IRIGA Essays, and the Iriga City Official Website. Findings showed that learners rated the material highly in engagement, relevance, clarity, and aesthetic value, with aesthetic value receiving the highest grand mean of 4.92. Expert validators rated the material very satisfactory, with an overall grand mean of 3.95. The study concluded that the material is valid, culturally meaningful, well-designed, and appropriate for English 7 instruction. It supports SDG 4 – Quality Education and SDG 11 – Sustainable Cities and Communities by promoting contextualized learning and preserving local culture. Its sustainability impact lies in strengthening educational, cultural, community, and institutional sustainability through localized instructional material development.
