Medgyes (1992) argued that NNESTs should be given the same chance as NESTs to be successful EFL teachers. He also discussed the strengths and weaknesses of both categories in his study. He stated the main strengths of NESTs as having high language proficiency and communicative competence, and the main strength of NNESTs as being successful learner models and having knowledge of their students’ L1. As a result, research has altered its attempts to find the better EFL/ESL teacher into attempts to discover how NESTs and NNESTs might complement each other. In other words, it is not about “who is worth more” (Medgyes, 1992, p. 340), but about how they are “worth more together” (Gill & Rebrova, 2001, p. 1). This concept has been explored through NEST/NNEST team teaching, as well as other professional collaborations between NS and NNS.
