Many of the trainees at CDI I met were already teaching English in Korea and some even had many years of experience. Yet, many of them failed one of the two written tests and had to retake it (some even 3 times). Some didn't do well at the mock teaching since they did things like forget the material, stammer, or got confused. I passed the 2 written tests on my first try and I did very well at the mock teaching, yet all I had was a TESOL certification and no teaching experiencing. However, I thought many of the trainees would become great or even exceptional teachers. They had good potential and as each day of the training week passed by, they improved. My point is why are you saying everyone who flamed CDI are bad teachers? If what you said is true, that makes you a fool. I just don't see what makes them bad teachers. Tell us why. Are they bad because they couldn't grasp CDI's teaching methods or didn't like CDI's structure? I knew a trainee who had smoked pot during the training week but I heard he got hired so does that make him bad? Many of the trainees (myself included) complained about CDI amongst ourselves because of deception on CDI's part. CDI didn't advertise in their brochure that the students had already grasped a good understanding of English and the teachers would be teaching a much higher level of English (almost to the point of a upper US middle school level). In fact, the brochure made it look like teachers would be teaching English at an elementary level when explaining CDI's concept. That broke our expectations. What I learned from my TESOL certification was suited for students with no knowledge of English to elementary level. I got the TESOL certification because that's what my recruiter recommended I do, but what I should've been doing was studying how to teach higher level English. During the training week, my recruiter also told me not to worry since I'd learn everything in about a month. Everything everyone had to learn had to be in one week. I was fed up with the lies so I left. So can you tell me why I should've stayed with an organization that lied to me? Why should I have stayed with an organization that said no teaching experience was needed?
