Background/ Objectives: The use of technology such as Learning Management System (LMS) is helpful during the pandemic to enforce distance learning in public schools in the Philippines. The Department of Education (DepEd) introduced various formats and platforms to teachers to cope with the situation mentioned and to attain continuous learning amidst any circumstances. However, in some cases like in Lananpin National High School (LNHS) which used to implement traditional method, modernization without consideration of technological acceptability issues has reduced the influence of e-learning and the desired academic achievement. In this regard, the researchers conducted this study to find out the level of acceptability and usability of i-lnhs; a learning management system for Lananpin National High School using an e-learning platform, Modular Object-Oriented Dynamic Learning Environment (Moodle), to address the existing learning gaps. The objective of this research is to examine the implementation of i-lnhs to help the teachers and students facilitate learning and easily monitor students' progress. Methods: This study used a descriptive and developmental research design. A questionnaire survey was used to assess teacher and student acceptance in implementation, content validity, and technological acceptability. Respondents were purposively chosen; 11 senior high school teachers and 40 senior high students. Data was obtained using Google Forms and was analyzed thereafter. Findings: The result showed that the implementation of i-lnhs in terms of functions and capability requirements, user interface and design, content validity, technical quality, and usability were acceptable to teachers and students. Therefore, the use of this technology could address the gaps of distance learning and the skepticism of teachers and students to adapt shift in learning methodology.
