The communicative approaches, code switching, and code mixing are measured generally in terms of bilingualism to comprehend the contents and improve the communication. To enhance quality education in order to achieve Sustainable Development Goals (SDGs) in general and SDG#4 in particular has been an enormous issue. This study aims to explore the use of code-switching as an instrumental tool in English language classes at secondary school level. Qualitative case study research design was used to explore the issue in further detail. Data were collected using open-ended semi-structured interviews from seven students and seven teachers of secondary schools in Lahore. Thematic analysis was used to analyze the data that emerged nine themes under three research questions. The study found that code-switching is an effective tool for comprehension, memorization, repetition, discussion, explanation, translation, and production of the contents as and when needed. It is implied that code-switching can be proved an effective communication tool at school level for quality education under SDG#4 and can bring about positive results. Surely, the findings cannot be generalized being of qualitative study, however, can be transferable/attributable to the public schools. The study concludes that if code-switching is incorporated in teaching methodology then quality education can be ensured and SDG#4 can be achieved. Based on findings, it is recommended that further exploration on SDG#4 and communicative approaches will help to achieve quality education.
