This study aimed to develop and validate a Content-Based Supplementary Skill Book in Writing for Grade 7 learners. The study determined the learners' competency level in writing, designed the skill book, and evaluated its validity and effectiveness. The study used a descriptive-comparative method and Research and Development design. Data were gathered from Grade 7 learners in V. Bagasina Sr. Memorial High School using teacher-made tests and questionnaires. Results showed that the learners' initial competency level in writing was low. The designed skill book was well-crafted, with measurable objectives, engaging discussions, and varied activities. The book's validity was high, particularly in curricular validity, usability, clarity, and innovativeness. After using the skill book, the learners' writing performance significantly improved, with large effects on recognizing purposes for writing, differentiating literary and academic writing, and identifying paragraph features. The study concluded that the skill book is effective in improving Grade 7 learners' writing skills, with a substantial positive impact on their performance.
