I think I would have taught myself to read even if no one else tried. I was raised in a family of readers and was trying long before I set foot in any school.
All of my four daughters were reading before they went to 1st grade. While in school, all of them read on levels well above their actual grade.
Everyone in my family reads; we all love to read. We will read a book, and recommend it to each other and then it will make the rounds through everyone’s house.
Of course, everyone in my family reads to the kids and grand-kids, everyone encourages the young ones to sound out words, associate pictures with the words and to put it all together. All learning (even the INTEREST in leaning) starts at home. No lawsuit that will ever correct THAT short-coming!
