My experiences. I started as a part-time teacher and quickly learned that I'm excluded from benefits such as yearly evaluation and salary increase, quarterly awards, perfect attendance incentives to name some. After a year and a half as part-timer, I decided to go full time. My advice to would-be applicants--go for a full time job.The good thingsI like their promotion criteria. If you start young and are looking at a long-term career with the company, you can start as ESL instructor then go for IELTS or TOEFL. SMEAG will give you the opportunity to achieve your goal because they are fully accredited to teach these high-stakes courses. Just be sure you really love teaching English. This will motivate you to stay for 5, 10 or 15 years. I regret that I started teaching there at age 57. I would have started earlier had I known that being a language instructor was such a broad field of interest especially if your students come from different cultural backgrounds and age groups. You don't only impart knowledge, you also learn from your students. This was enough compensation for the average salary rate which the laws of this country set for classroom instructors and teachers.
The challengesOne thing lacking at SMEAG Capital Capus where I worked, was a cafeteria for the teaching staff. The teachers would eat in any rooms during meal times and sometimes the smell of food linger in the air while you conduct your class. Water, though is free and you can have as much as want in a day of school.
