This study developed and evaluated a Strategic Intervention Material designed to strengthen culinary skills competency among junior high school learners in Technology and Livelihood Education. It used an iterative design-and-development approach with an embedded repeated-measures competency evaluation conducted at Rang-ayan National High School in the City of Ilagan, Isabela. Learners who demonstrated difficulty in selected cookery competencies participated through criterion-based cluster sampling, while qualified experts assessed the material’s content alignment, clarity, usability, technical accuracy, and assessment suitability. Data were gathered through a diagnostic competency test, an analytic culinary performance rubric, and a material evaluation questionnaire. Instrument quality was established through content validation, pilot testing, internal consistency analysis, test reliability, and interrater agreement. Many-Facet Rasch Measurement calibrated learner ability, task difficulty, performance criteria, and rater severity, while a linear mixed-effects growth model examined competency changes across baseline, midpoint, and final assessment. Results showed that the material achieved excellent expert evaluation and strong psychometric properties. Learners improved from emerging to proficient performance across preparation and organization, procedural accuracy, tool use, measurement, sanitation and food safety, time management, product quality, and independent task completion. The strongest outcome was observed in sanitation and food safety, whereas time management and independent performance remained areas for continued support. The findings support the use of focused, visually guided, and performance-based intervention materials in strengthening cookery instruction and learner competency.
