For anyone who wants to teach in China, I highly recommend Jeda. I have worked with other recruiting agencies in the past and from my experience, Jeda has offered me the most assistance.
Jeda made a great effort to help me up until I arrived in China. If I had questions, they provided the best solutions. I have heard stories of people never hearing from their recruiters after they take a job offer, but I never experienced this with Jeda.
I felt they were honest, listened to what I wanted in a job (rather than trying to fill the next available spot in any school), and gave immediate responses. I know that anyone going through Jeda will find what they need.
