Hello, Matthew. I'm 48. I completed my Advanced TESOL Diploma about a year ago. I'm now living in Colombia. For me, age hasn't been an issue at all. The bigger problem has been lack of experience. However, I've worked for two different institutions, by the hour, since I've been here; as well as having private students in my home. In July, I'll begin my first fulltime contract (salary) position with British College, a leading language institute here. Keep trying. There are a lot of employers who won't give a second thought about your age, especially if you are going to teach adults.
Hey Guys! I really don't think age is the problem, with me its the fact that most places are looking for a Bachelors Degree, i have my Advanced Diploma in TESOL and every-time i've applied for jobs i've been told that its not enough.
