SEW: School Event Website Development and Validation

School event awareness plays a crucial role in fostering student engagement and holistic development. However, many institutions, including Bataan National High School – Senior High School (BNHS-SHS), continue to rely on inefficient traditional methods of event dissemination. This study aims to design, develop, and validate a School Event Website (SEW) to enhance event coordination and accessibility for BNHS-SHS students. A preliminary survey conducted among 147 student participants revealed signif-icant gaps in communication. Specifically, 56.47% reported a lack of timely event updates, 64.63% found the announcement methods ineffective, and 74.83% experienced difficulties with online registration. The study follows research and development (R&D) design, incorporating the Web Development Life Cycle (WDLC) to systematically create SEW. A sequential exploratory mixed-method approach was employed, involving surveys, interviews, and expert validation to assess SEW’s content, functionality, and usability. By addressing inefficiencies in school event management, this research seeks to bridge the communication gap and improve student participation. Findings from the Development Phase Evaluation highlighted the need for essential website features such as an event calendar, a search function, and a user-friendly interface. The Website Usability and Functionality Validation among students and experts (mean score: 3.81/5) indicated that SEW was generally functional and accessible but required improvements in loading speed (3.48) and navigation intuitiveness (3.64). Content accuracy and responsiveness received positive feedback, with accessibility rated the highest (4.06). The study concluded that SEW effectively enhanced event awareness and engagement but required further optimization in speed and user navigation. It recommended implementing technical improvements, clearer event details, and regular website updates to maximize usability. By addressing communication gaps in school event management, this research contributed to the advancement of digital event platforms in educational institutions.
