Well EFL and ESL are quite different. EFL is generally structured around acedemics. It's taught and tested like math. Most of the time the real 'use' of the learning on the students part is for testing, not for speaking.

Whereas true ESL is more like support. Students have so much exposure and chance to use the language, the teacher is just guiding learning.

In general ESL doesn't focus on teaching grammar points like EFL.
