I have been an EFL teacher for 20 years and I started being a teacher trainer in 2008. Before that I was an administrative assistant at an International Cement Company (HOLCIM Group in the North of Mexico). The advice that I would give to all my CELTA trainees is to be organized and have sound time management skills. As the course progresses the demands are higher and if the time allotted to write lesson plans, write assignments and read is tight, it will take a toll on energy levels. Focus on the progress you are experimenting, and be receptive and open to feedback, our main goal as tutors is to guide you to be successful.
