To achieve this objecti ve, it is necessary to equip students with “21st century skills” in additi on to language skills. A crucial factor that determines the success of the programme is the teaching material. The Advanced Level GE textbook is the primary teaching material for the GE course in schools nati onwide. This study explored the representati on of 21st century skills in this textbook by employing Qualitati ve Content Analysis (QCA) to systemati cally categorize and evaluate instances of 21st century-related acti viti es and discussions within the textbook. Although the study investi gated twelve 21st century skills, in this paper, we focus on the 4Cs (Creati vity, Criti cal Thinking, Communicati on, Collaborati on). The results indicate that although the 4Cs were the most visible skills and consti tuted the majority of occurrences (85.27%), some important aspects or subskills were not adequately represented. In additi on to other outcomes, the presentati on will mainly contribute to English Language teaching material development and evaluati on at both policy and implementati on levels.en21st century skillsEnglish Language Teaching (ELT)General English (GE)TextbookQualitati ve Content Analysis (QCA)Articlehttps://doi.org/10.54389/FUMR6787
