CIEE is incredibly organized and supportive. The staff is quick to respond and works efficiently and effectively to assure your placement is the best fit for you. (Thank you Luke Beland, Sagan Pope, and Brad and Yumi!) They take care of the tedious paperwork and very assistive of any hiccups that may occur along the application and hiring process. The entire program is very organized and efficient. I really felt that I had an entire team working for me the whole way.
I really enjoyed meeting the rest of the CIEE staff and team members here in Korea (especially Brad!!!). They are a great support system and even made great friendships and connections through our orientation and meet ups.
Personally from my experience in South Korea, a TEFL is not necessary at most hagwons (private schools) nor do they even ask. However, if you plan on applying for EPIK (public schools), it is necessary. This is important to keep in mind when paying for the course. The TEFL certification opens up a lot of opportunities for me to expand my teaching career, however, if you plan on teaching in Korea for a year at a hagwon, I would not recommend taking the course. It is not necessary.
Overall, I had a great experience with CIEE.
