About 25 years ago (more or less), dyslexia was the favorite excuse of the schools of why kids couldn't read or write properly. I read a while back that a teacher was talking to a doctor who diagnoses dyslexia (among other conditions), and he got a surprise.
Just curious, he asked the doctor how they diagnosed it. The doctor said that they would tell the parents to put the kids in a pure-phonics class for six months. If they improved, it wasn't dyslexia but the teaching methods the schools were using. This was years ago, and the schools are still using the same ineffective, archaic methods.
In truth, it is much more profitable for the schools to produce 'learning disabled' students, because they get more funds to deal with them. The fact that the schools are causing the problem obviously isn't an issue to them.
It's a good thing my mother taught me how to read, because the schools certainly aren't much good at it.
