I teach groups of kids from about 13/14 and adults from beginner to Advanced (But not profficiency)... However, I do not teach Matura and I don't teach young kids, but if you are prepared to do that (and trained) more hours would surely be available. Essentially from elementary to advanced.
The hours are from 14 - 20.00 generally (obviously, we haven't filled all the courses yet)
The books we use are:
Winners
Adventures
English File
Headway
FCE Masterclass
CAE Mastercass
as well as others - and our own materials of course!
And the pay is comparable to Warsaw: 35złotch an hour (more if you have to give in company lessons) - but it really is best to negotiate with my boss!
If you have any more questions, don't hesitate to ask
And the right candidate could start on the 2nd of October
