Within the framework of comprehensive reform in general education in Vietnam, enhancing the quality of English language instruction has emerged as a vital goal. An approach being employed is Content and Language Integrated Learning (CLIL) in English language education. This study employs a mixed-methods approach, integrating quantitative and qualitative research, to assess the current implementation status, evaluate effectiveness, and propose modifications for the application of CLIL in 10th-grade English instruction, as perceived by teachers and students at three Vietnamese high schools. The research findings indicate a different utilization of CLIL among schools, combined with an inequality in the integration of the four components of the 4Cs framework. Although most students recognized the beneficial effects of CLIL on their engagement and learning confidence, only a minority felt entirely assured during participation in activities. Additionally, the research highlights an effective CLIL method consisting of five key elements and recommends strategies to establish a psychologically secure learning environment. Effective implementation of the CLIL approach necessitates the enhancement of teacher training, the development of specialized resources, the improvement of evaluation systems, and the creation of favorable learning settings. Future studies should broaden the scope and create CLIL models tailored to various regions of Vietnam.
