If this lad has been attending english lessons for the last 3 years, but is still unable to read or write, what have those lessons actually achieved for him? Surely they have simply been a waste of time, for him and for you.
"I've been his English teacher for three years, and I can assure you that he has also been taught properly"
Hmm, you have been thru the motions of teaching him, but he hasn't been able/willing to learn.
If he does indeed have severe dyslexia, he needed different/more specialist method than you provided. His time has been wasted, and he has been made to feel like a patsy in the process.
If he isn't dyslexic, then the whole academic process has passed him by. In this case, rather than sitting him down and force feeding more of the same, accept that he isn't an academic, and let him move on to a practical course instead, so that you can devote your time to those who can and will benefit from it. If he is able to learn to read, he's more likely to want to acquire the skill when he realises he needs it to identify the correct spare parts for the Fiesta he's putting back on the road.
Illiteracy among school-leavers is becoming more prevalent. Either we're breeding MANY more kids with dyslexia problems, or our education system is alienating more and more children.
I know which I believe is more likely....
