I so fundamentally disagree with daftpunk and bubbleOseven - fwiw, none of my children have ever needed this, they are all high-achievers, but I have seen how kids, particularly summer-born boys REALLY struggle - it's not their (or their parents') fault that they are 11 months younger than some of the children in their class, and without intervention, these kids really can fall through the cracks. If your parents work, there is precious little time to do the 'reading recovery' which is needed, and which I have seen make MASSIVE amounts of difference - it helps them when they need the help, which then enables them to access the rest of the curriculum.
Or perhaps education isn't about teaching children to read?
