Introduction: Integrating digital tools and resources into classroom instruction has become increasingly essential in modern education. As technology advances, teachers face the challenge of effectively integrating digital learning content into dynamic classroom practices. This paper explores the competencies teachers require for this task, aiming to contribute to understanding teacher professional development needs in digital integration. Purpose: This study aims to investigate the competencies required by teachers for the successful integration of digital tools and resources into classroom practices. Methods: A comprehensive literature review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) diagram flow to address this aim. A total of 84 articles published from 2000 to 2024 were systematically reviewed, focusing on publications in English that addressed the professional development of teachers, technology integration into classroom practices, and digital competencies. Articles that did not meet these criteria were excluded from the analysis. Results: The synthesis of findings from the literature review highlighted the knowledge base of teachers' professional development needs in digital integration. The review identified critical competencies for successful digital integration, including technological proficiency, pedagogical knowledge, and content expertise. Additionally, theoretical frameworks such as Technological Pedagogical Content Knowledge (TPACK) and the SAMR model guided the exploration of teachers' competencies and their implications for instructional practices. Discussion: The implications of the study's findings extend to educational policy, teacher training programs, and classroom practices. By identifying critical competencies for successful digital integration, this study provides insights into areas for further research and teacher professional development. Moreover, the discussion delves into how these findings can inform the design of effective teacher training programs and support the development of pedagogical practices that leverage digital tools to enhance student learning outcomes. Limitations: Despite the thoroughness of the literature review process, it is essential to acknowledge certain limitations. The study focused primarily on articles published in English, potentially excluding relevant research published in other languages. Additionally, while the PRISMA diagram flow facilitated a systematic review, some relevant articles may need to be noticed. Conclusions: In conclusion, this study contributes to understanding teacher competencies required for effective digital integration of learning contents in dynamic classroom practices. The study identifies critical competencies and highlights areas for further research and teacher professional development by synthesising findings from relevant empirical studies and theoretical contributions. Ultimately, the findings have implications for educational policy, teacher training programs, and instructional practices to enhance student learning outcomes in the digital age.
