I've been given a rough budget and told to submit a list of recommendations for course books for older teens/adults. Ideally they'll have an accompanying audio CD and it doesn't matter if they don't have separate teacher and student course books (although that would be good as the students could then have a book). A series of books going right from beginner to advanced would be preferred and it's General English as I'll have the add the specialist content myself.
Er, HELP?! I've only ever used English File and Headway and before this job I did EAL support in an international school and was a private governess, so both with children and neither involved teaching from a course!
