This study assessed the performance of Grade 9 learners in Fancy Nail Design at Dupax del Sur National High School, Domang, Dupax del Sur, Nueva Vizcaya, during the School Year 2025–2026, as a basis for developing a contextualized instructional material. Specifically, it aimed to improve learners’ performance in terms of water marbling, nail art accessories, nail art stickers, and nail art stamping. The study employed a quantitative developmental research design utilizing the performance tasks to assess the learners’ skills in Fancy Nail Design. The respondents were Grade 9 learners selected through purposive sampling. Data were gathered using an evaluation sheet based on the Curriculum Guide (CG), covering competencies in nail preparation and cleaning, application of nail products and fancy nail designs, client nail maintenance practices, and proper waste disposal in accordance with environmental and safety regulations. Findings revealed that the learners obtained an overall mean score of 65.08 (SD = 5.96), interpreted as “Did Not Meet Expectations.” Water marbling obtained a mean score of 90.25 (SD = 3.81), nail art accessories 39.43 (SD = 6.08), nail art stickers 44.63 (SD = 6.55), and nail art stamping 86.00 (SD = 7.48). The results indicate limited competency in Fancy Nail Design, particularly in applying nail art accessories and stickers. The study concludes that contextualized instructional materials are necessary to improve learners’ practical skills and creativity in Fancy Nail Design. Hence, teachers are encouraged to utilize competency-based and hands-on learning activities to enhance learners’ performance.
