This investigation examines how teacher autonomy is essential in developing innovative methods within language schools by applying the Self-Determination Theory (Deci & Ryan, 2019) and the Professional Capital Framework (Hargreaves & Fullan, 2022) as foundational contexts. The study evaluates educational autonomy through its three facets—decision-making autonomy alongside curriculum design autonomy and professional development autonomy—to understand its potential impact on teacher creativity as well as adaptability and student engagement. This study collected data from 55 intermediate teachers across Safir Language Academy branches through a cross-sectional quantitative approach and used validated tools such as the Teacher Autonomy Scale and the Inventory of Innovative Teaching Practices. Research findings show that professional development autonomy (β = 0.42, p < 0.001) leads as the foremost predictor of innovation with decision-making autonomy (β = 0.35, p < 0.001) as the next predictor and curriculum design autonomy (β = 0.28, p < 0.003) following last. Branch contextual elements like leadership support and resource availability significantly influence this relationship because branches showing collaborative leadership support demonstrate that institutional factors promote innovation variables. The practical outcomes highlight the need for adaptable curriculum policies and professional development alongside opportunistic leadership to promote pedagogical innovation. The findings of this study provide guidance for educational policy development and administration procedures along with a proposal for systemic modifications to enhance teacher control. The research faced constraints due to its limited sample size and single-institution focus which prompted recommendations for conducting longer-term studies alongside comparative research. The study's findings contribute to expanding the dialogue around teacher autonomy and how innovative practices can enhance student learning.
