I'm a private reading tutor. I work with many children to bring them up to grade level in reading and spelling. The majority of students I work with, even those with a learning disability diagnosed, really just need basic, structured remediation that isn't being addressed by the school curriculum; or it is being addressed but not efficiently and thoroughly. (Kids are pulled out once a week for some extra help, but not systematically and the help isn't fast enough.)
I think one one one with a skilled tutor is probably best, but I have seen the Kumon program and it seems more than adequate for many students, and is probably more affordable than a private tutor.
A physician that has encountered many children with learning disabilities. I agree with the fresh and wise words of the PP. My recommendation/therapy of Kumon to a close and frustrated family friend in Boston with a 5th grader performing many grade levels below par has worked wonders for this girl after 13 to 15 months. I know many other children who have benefitted by the discipline of these frequent (daily) short working sessions in math and reading.
This does not mean this approach will benefit all children; but scanning the commentary of shrill and ignorant (no one gives a damn about any Yale or Big 3 degrees) individuals carping away provides for humorous entertainment, solely.
I have no stock or financial interest in Kumon (or any similar entity); but it's about the well being of the child, stupid, and not the paranoia and insecurity of people consumed with real or imagined motives of the parents of kids in Kumon -- as if their gifted children are somehow short changed or their American dream fantasy childhood threatened.
Warning: if you are allergic to Kumon please stay away for your own health and carry an Epinephrine Pen at all times
