This entry delves into how technological platforms can facilitate student self-assessment (SSA) activities in L2 writing, thereby streamlining feedback provision, augmenting learner autonomy, and refining writing proficiency. It begins with an introduction to the pivotal features of SSA and the essential conditions for its successful integration into L2 writing. Subsequently, it reviews key learning theories that underpin effective SSA, offering a theoretical foundation for its practice. The literature review subsequently examines the potential of technology-enhanced SSA to foster learner autonomy, highlighting both its advantages and associated challenges. Two case studies illustrate how EFL teachers have successfully implemented technology-enhanced SSA to improve learners’ autonomy in L2 writing. Following this, an SSA implementation framework is proposed, offering educators a structured approach to effectively integrate technology-enhanced SSA into their teaching practices. This framework outlines practical steps, strategies, and guidelines to help educators foster learner autonomy. The entry concludes with a discussion of the pedagogical implications for the implementation of SSA in educational settings.
