Is it better to teach EFL to teens at Elementary (beginner) level, or Upper-Intermediate at summer school?

Question

Which level do you consider to be easiest to teach (bearing in mind that these are Italian teenagers)?

Answer 1

DEFINITELY at the Beginner level. YOu can move FASTER, but you have to start with the basics.

You can't play piano if you don't know the notes! Set a goal and move on it

Answer 2

Get in early, because once you get a student at the middle or high school level, they have either become set in their ways, solidified their bad habits, or just aren't interested like elementary students are.  EFL, or ESL is completely different than other subjects that someone might be able to grasp later in life.

Answer 3

I prefer beginning level as you can really progress and can then be assured your students are learning what they need to learn.
