I recommend iTTi Istanbul. The low class size is one major reason to take this class. I appreciate immensely having the freedom to ask clarifying questions at all times. And because the workload is compressed and detailed, having the environment that supports any follow up questions at any time i believe is crucial to your development.
Also, the instructors are approachable and do everything they can within their power to accommodate your learning style. And I do not say this lightly. All the students, based on their own personality and learning behavior, were adapted to throughout this relatively inexpensive course. So in the end, although the course is inexpensive as I say, it is still a sizable investment for most any individual and I am happy I chose iTTi Istanbul.
The day I received my TESOL certificate is one of the most important, satisfying accomplishments of my life.
Thank you iTTi.
