Generally speaking relying on student feedback as an assessment of teacher quality doesn't work terribly well, unless of course said students are impartial. A better monitor of feedback would be evaluations by both foreign and domestic staff, on a rotating schedule.

Meten itself seems to have a slightly average evaluation on a number of review websites, and that puts it above many of the other larger chain schools.

As a general rule though, state your truthful nation of origin. I do believe you are of the domestic persuasion.
