Instructional materials play a vital role in enhancing the teaching and learning process, particularly in skill-based subjects such as dressmaking and apparel pattern-making. This study aimed to determine the validity of the Mastering Apparel Patterns (MAP) module as an instructional material for Technology and Livelihood Education (TLE). Specifically, the module was evaluated in terms of its alignment with the Most Essential Learning Competencies (MELCs), assessment, instructional design, readability, and instructional quality. The study used a descriptive-quantitative research design. The study used purposive sampling to select the six instructional experts who acted as validators. All six had a master’s or a doctoral degree and a minimum of three years of teaching experience. The researcher developed a validation tool which was used to collect data. From the data collected, the weighted mean and standard deviation were computed. The results indicated that the MAP module had a validity rating of 3.84 (Very Satisfactory). The highest rated dimension was MELCs (M = 4.00, SD = 0.000), followed by assessment (M = 3.93, SD = 0.078), instructional design (M = 3.83, SD = 0.136), readability (M = 3.80, SD = 0.400), and instructional quality (M = 3.63, SD = 0.379). This shows that the module meets the standards of the curriculum, supports the use of coherent instructional strategies, and provides adequate and accessible content. The study concludes that the Mastering Apparel Patterns (MAP) module constitutes legitimate instructional material and is suitable for enhancing the teaching and learning of apparel pattern making skills in Technology and Livelihood Education.
