Continuous Professional Development (CPD) in teaching has emerged as a vital component in enhancing the quality of education, particularly in the context of English language teaching in Uzbekistan. This paper explores various models and approaches of CPD, including Communities of Practice, Action Research, Collaborative Inquiry, Job-Embedded Professional Learning, and Microteaching. Additionally, it discusses the benefits of CPD for educators, students, and the educational environment, along with the challenges and barriers to its effective implementat ion. Drawing on existing literature and empirical evidence, the paper underscores the importance of tailored and differentiated CPD programs that address the diverse needs of teachers while providing sustained support and opportunities for reflection. By addressing these challenges, policymakers and educational stakeholders can foster a culture of continuous learning and professional growth among teachers, ultimately improving student learning outcomes.
