The study entitled, "Evaluation of the Utility and Usability of the Learning Resource Management System of Las Piñas National High School-Learning Resource Center of Junior High School", aims to gauge the usefulness of the curated learning resource management system of the researcher and others. To ensure the best version of the portal, it was placed under 2 kinds of evaluation. First, from software evaluators--a bot or AI (artificial intelligence) that evaluate the website design in detail. It yielded a total of 90% grade from WebsiteGrader and a 73.8% total rating from Qualidator. The second evaluation was the user experience of the target audience of the resource portal. Data was collected through the opportunity sampling method. A Likert scale survey using a Google Form was implemented for grade 10 STEM students and science department teachers. The utility and usability of the portal were the main subjects rated by the respondents. To sum up, the overall UX (user experience) by the students and teachers resulted in 76% being very satisfied and 25% being satisfied with the LRMS. The website is very useful for students, parents, and teachers. Some minor enhancements will be made based on the comments and suggestions of the respondents to provide a richer experience when the LRMS is officially launched to the public.
