This study designed and validated supplementary learning materials for the Clothing Construction course and assessed the skills and learning challenges of fourth-year Bachelor of Technology and Livelihood Education major in Home Economics (BTLED-HE) students at Polangui Community College during Academic Year 2024–2025. A descriptive-developmental research design was employed. Through total enumeration, 78 students from two sections participated, while five clothing-construction experts composed of a TESDA trainer and TLE teachers with National Certificate II and/or Trainers Methodology Certificate I evaluated the developed material. Data were gathered using a researcher-developed questionnaire and an expert validation tool. The instruments underwent review, dry-run administration, and reliability testing through Cronbach’s alpha. Weighted mean and a five-point Likert scale were used for analysis. The respondents were highly proficient in drafting and cutting patterns (M = 4.22), preparing and cutting materials (M = 4.44), sewing casual apparel (M = 4.27), and applying finishing touches (M = 4.30), with an overall mean of 4.31. Nevertheless, comparatively lower ratings were recorded for pattern manipulation, simple calculations, alteration of completed garments, and analysis of quality deviations. The principal challenges were lack of practical experience (M = 3.79), insufficient learning resources (M = 3.76), time constraints (M = 3.73), and limited exposure to industry standards (M = 3.71). In response, supplementary materials were developed around the four TESDA-aligned competencies. Expert validation produced an overall mean of 4.94, interpreted as strongly agree, across objectives, content, format and language, presentation, and usefulness. The study concludes that the material is curricularly valid and suitable as a self-directed, competency-based resource for strengthening clothing-construction proficiency. Its adoption, classroom implementation, and subsequent effectiveness evaluation are recommended.
