The educational system in Nigeria today has been largely imported. This is because no one country is self-reliant without utilizing other countries’ technologies and good educational ideals. A consideration of a stable and functional educational system should involve consistent re-training of teachers for efficient implementation of the curriculum for Nigerian schools. Consistent development and re-training of teachers in English language will improve capability of teachers for efficient use of the curriculum, being the implementers of the educational programmes. As such, there is the need for teachers’ re-training programmes and adequate supply of human and material resources for educational productivity and consolidation of the Nigerian educational system. It is the concern of this paper to consider the concept of training and re-training of teachers in English language, efficient curriculum implementation by professionally trained teachers and curriculum innovation for qualitative teaching outcome.
