This research study investigates the relationship between Task-Based Language Teaching (TBLT) and English language proficiency among students in private schools in Erbil, Kurdistan. The study is underpinned by communicative language teaching principles and second language acquisition theories, which emphasize the importance of meaningful communication and contextual learning. The research hypothesizes that TBLT is associated with improved language proficiency, enhanced intrinsic motivation, and increased confidence in using English for real-life communication. The study's findings confirm these hypotheses, demonstrating a statistically significant positive relationship between TBLT implementation and English language proficiency. Moreover, TBLT outperforms traditional teaching methods in fostering language proficiency. The study also reveals that TBLT positively correlates with increased intrinsic motivation, contributing to improved language skills. Contextual learning afforded by TBLT is found to enhance practical understanding of English language skills. Additionally, TBLT enhances students' confidence in using English for real-life communication, a vital aspect of language proficiency. These findings suggest the potential of TBLT as an effective pedagogical approach for enhancing English language education in private schools in Erbil. The study concludes by offering recommendations for the implementation of TBLT and the importance of teacher training, motivational strategies, and long-term impact studies in the context of language education.
