Ridiculous. If these parents would put more time into meaningful activities with their children, like counting trucks, playing with Legos, cooking, crafts, cutting with scissors and nature walks their kids would be both well-rounded and less stressed.
I started homeschooling when my oldest was in 3rd grade and still not reading.

I had but one goal for the year: learn to read. We read, we hiked, we played, we read, we wrote, we read, we baked, we read, and by Christmas John was reading. By the next year he was reading chapters books and begging for Shakespeare(weirdo.) I always encouraged him to read for fun and he is one of the most well-read adults I know.
I did the same thing with his sister. She had a hard time learning her letters--even in 1st grade there were 3-4 she wasn't sure of. Once again the old goal came out: learn to read. Same method. Eleni learned to read and she loves to read novels. She isn't as broadly read as her brother(he loved all teh classics, she loved Harry Potter) but Literature is her best subject.
Learning to read is very individual. I think pushing pre-K kids to read is a huge mistake; it puts unnecessary pressure on very young children, for what? So they can be the smartest, fastest reader in their 1st grader class? I hate to tell you, but by the time they all reach middle school you can't tell the ones who read at 3 from the ones who read at 8.
