The National Education Development Project (NEDP) is one of the most important attempts to improve the quality of teacher education in Turkey. NEDP focused on the development of practice in pre-service secondary school language teacher education in Turkey. NEDP supported this research to explore student, mentor, teacher educator, and mentor trainer opinions and experiences in depth and understand the actual implementation of school-based teacher education at schools. Individual interviews were conducted in a British University to explore participants' perceptions. This paper will discuss each issue which emerged from the data separately to highlight the issues that appeared important.
