The English Language curriculum in Malaysia has undergone a transformation with the adoption and implementation of the Common European Framework of Reference (CEFR). This study aims to contribute to the understanding of how the Common European Framework of Reference for Languages (CEFR) is interpreted and implemented in the English language curriculum of primary schools in Malaysia. Additionally, it seeks to identify steps that can be taken to enhance the implementation and address potential challenges. The research methodology employs a document analysis approach to assess issues and challenges in implementing the Common European Framework of Reference for Languages (CEFR) in the English language curriculum of primary schools in Malaysia. The study's findings are analyzed with a focus on identifying key issues that arise during the implementation of CEFR in the teaching of English in primary schools. The study's findings reveal three main issues and challenges faced by teachers in implementing CEFR in primary schools. These include limited awareness and knowledge among teachers, a lack of training and professional development courses aligned with CEFR, and a shortage of teaching and learning resources aligned with CEFR. Based on the research findings, the researcher proposes further studies involving additional methodologies such as surveys, interviews, or direct classroom observations to gain a deeper understanding of practical experiences in implementing CEFR. The findings will inform educational policymakers and stakeholders, enabling them to formulate targeted strategies for improving the effectiveness of CEFR implementation.
