What do English language learners want from a tutor?

Students want specific outcomes when they pay for individual instruction, just as when they pay for a meal at a restaurant. No instructor can guess in advance what even one student wants, let alone students in general. Only students can identify their own motivations. Then, they can express these motivations to the instructor. Only then should the instructor start to form any concept or approach to engaging the student.
You can see by my ratings, that I have mostly succeeded in accomplishing what the student wants. If I only knew for what reasons some students did not rate me highly, I would be able to work on improving that area. Without that input, I must try to discover my weak points on my own, through self-examination. In what ways do I fall short? What are my strong points? By asking these questions often I try to discover what each new and continuing student wants, each time we meet or interact.
