The present study provides a comprehensive exploration of Task-Based Learning (TBL) as an innovative pedagogical framework for developing communicative competence in English as a Foreign Language (EFL) classrooms. Rooted in the principles of communicative language teaching, TBL shifts the instructional focus from form-based to meaning-based interaction, allowing learners to engage with authentic linguistic tasks that mirror real-life communication. The research synthesizes insights from contemporary scholarship (Ataniyazova & Akmammedowa, 2025; Alasal, 2025; Zokirovna, 2025; Nghia & Quang, 2021), emphasizing that TBL enhances not only linguistic proficiency but also pragmatic and sociocultural awareness. Through purposeful communication, learners develop grammatical accuracy, discourse management, and strategic competence—key components of communicative ability. In this model, classroom activities such as problem-solving, role-plays, and information-gap tasks promote learner autonomy, collaboration, and motivation, which are essential for long-term language acquisition. Studies conducted across various educational contexts (Nghia & Quang, 2021; Bakhronova, 2024) demonstrate that students exposed to task-based instruction display greater fluency, interactional confidence, and willingness to communicate compared to those taught through traditional, teacher-centered methods. Moreover, recent findings highlight the role of integrated skill development—particularly speaking and listening (Nabieva, 2025)—and the significance of paralinguistic elements such as gestures and facial expressions (Ismayilli et al., 2025), which complement verbal communication and deepen intercultural understanding. By situating learning within authentic, communicative contexts, TBL facilitates a dynamic environment where language is both the means and the goal of learning. Ultimately, this study argues that Task-Based Learning contributes to a holistic form of communicative competence, encompassing linguistic, pragmatic, and intercultural dimensions. It positions learners as active constructors of knowledge, capable of navigating real communicative scenarios confidently and appropriately. The paper concludes that incorporating TBL into modern EFL pedagogy not only enhances communicative efficiency but also prepares learners for the globalized linguistic demands of the 21st century.
