This study examines the effectiveness of Information, Communication, and Technology (ICT) integration in schools, particularly in public secondary schools in Kuala Lumpur, Malaysia. The research aims to analyze teachers' perceptions of ICT integration's impact on teaching and learning. A survey questionnaire was distributed to 101 teachers, and data were analyzed using SPSS (version 21) for both descriptive and inferential statistics. The results indicate that ICT integration is highly effective for both teachers and students. Key findings include the importance of well-equipped ICT tools and facilities, the role of professional development training programs, and the need for strategic planning and policymaking in managing ICT integration. The study concludes that effective implementation and support from school management are crucial for the success of ICT integration in schools. Future research should explore additional aspects, such as comparing public and private schools and addressing the challenges faced by teachers in integrating ICT.This study examines the effectiveness of Information, Communication, and Technology (ICT) integration in schools, particularly in public secondary schools in Kuala Lumpur, Malaysia.
