— Under the K–12 Basic Education Curriculum, Introduction to the Philosophy of the Human Person is a required course for senior high school students. Self-Learning Modules (SLM) based on the Department of Education’s Most Essential Learning Capabilities (MELCS) are used in modular learning. This study assessed the philosophy module development for senior high school students in Tagapul-an District in the school year 2024–2025. It utilized the quantitative and qualitative approach to evaluate the acceptability of the philosophy module, and used developmental research to produce a module. Results indicated that the overall structure of the module is generally well-organized. The module does a commendable job of presenting philosophical concepts in a logical sequence, starting with basic ideas before progressing to more complex topics. The Mean of 3.82 reflects a high level of content validity, affirming that the teachers found the module to be well-structured and appropriate for the intended educational objectives. Experts rated all indicators as “Accepted,” with scores ranging from 3.65 to 3.99. Mean of 3.79 reflects a strong consensus among the experts that the module is highly acceptable, reinforcing the validity of the content and design across all groups of assessors. The overall structure of the module was praised for being well-organized, with clear separations between sections that allowed students to track their progress easily. Experts and teachers suggested that the module’s structure be revised to ensure that complex concepts are introduced gradually, allowing students to build their understanding step-by-step and avoid feeling overwhelmed by difficult material.
