Drawing on 69 conceptual publications, the paper identifies three major themes shaping the contemporary landscape: conceptual integration, contextual responsiveness, and technological adaptation. These themes reflect how instructional leadership is being redefined to meet the demands of increasingly complex and dynamic educational environments. The review concludes by proposing future trajectories that emphasize equity, localized leadership models, digital transformation, and system-level coherence, positioning instructional leadership as a vital and evolving force in educational improvement.Business, Management and AccountingSocial SciencesArts and HumanitiesInstructional leadership in a 21st century global context: a conceptual reviewArticleSCOPUS10.1080/13603124.2026.26651142-s2.0-10503753385314645092
