Teacher education is the structured preparation and ongoing professional development of teachers, encompassing the knowledge, skills, dispositions, and ethical responsibilities required for effective teaching and learner support [1][2][3][4][5]. It includes initial teacher education (pre-service) and continuing professional development (in-service), with components such as subject knowledge, pedagogy, classroom assessment, inclusive practice, and supervised practicum in authentic school contexts [1][2]. Teacher education is characterized by integration of theory and practice, reflective inquiry, standards-aligned competencies, and continuous improvement across the professional career. In policy and research, the term denotes a formal professional formation system for teachers, distinct from ad hoc training that lacks coherent curriculum, practice-based mentoring, and quality assurance [2][3][4][5].
