No, it means they have all round better fluency than the poor students under your tutelage. If you understood anything about either IELTS or ESOL you would know that and the original post is just further proof of their superiority over the crap 5 minute bribable oral test you give twice a year! Again, your lack of knowledge on the subject of IELTS and ESOL has been proven with your silence in two different threads now... Are you going for the 'shown-up' hat trick?!

I am not a test teacher, not that that's an insult. I give my students fluency in all skills, which prepares them for academic of business application of their skills, not just to chat about the services offered by different countries prostitutes at a bar with a sad, desperate aussie ex-pat...
