I used to teach English for 3 years to boys of a different level and age. Actually, from the very beginning to the final exams. Most of all I liked it at the end:))) Well, we started from the alphabet and sounds, then simple words and grammatical structures. Then increase number of words. Most of all programs I like the one by V. Skulte.
Unfortunately, I have no experience
of teaching edults. But I've decided to try:)

Have_nothing, tell me please how do you usually try to identify the level? With help of some tests or in some other way?

Kim_Berly, thank you very much) Of course, I will ask you if I need)

Well, about the programme by V. Skulte, what is it about? I mean what advantages does it have? Could you tell about it in some words? And where can I find it?

Jelllyjam, first of all i ask to bring their study books and look through them... then I make some tests for them or exercises ant then ask to answer why they have chosen this or that variant, and then analyse everything :)

Have_nothing, but do you have some tests or do you make them at the time of tutoring?

Jelllyjam, i had some of them but a do not have them now

I began thinking about being a tutor some months ago, because last year I entered the Linguistic University. And study there by correspondence. My second speciality will be a teacher of English. Therefore I started to think about teaching.
From what it’s better to start with?.. It’s a difficult question. I will answer exactly when I become an experienced tutor. Now I can only try to suppose that we should give children the information, which is useful and interesting to them. It may be drawing pictures and trying to name or describe it in English. It may be colours – trying to remember them well. Or it may be different simple games, which help children to develop themselves. We shouldn’t teach little children grammar or spelling, maybe phonetics a little. But it’s my personal opinion.
The other day I’m going to advertise myself in newspaper as a tutor. I’d like to find such parents who want their children study English. I haven’t practice enough, but I’ll try. I hope this my idea will be successful.

Crazy_Smile_1986, thank you for your detailed answer) Good luck!
And if you find pupils write about it, please)
