There is little reason to be concerned at this point. She is doing what first graders have traditionally done. There is every reason to be suspect of a curriculum which attempts to teach skills which developmentally may be inappropriate. To some extent, if it were wise to be teaching children across the board how to read in kindergarten, educators would have done so long ago. This is not to say that there are not some children who are able to learn to read prior to first grade, but in general it is not a reasonable expectation. It may well be that your child is not a good match for this particular program, but that reality does not mean that there is something wrong with your child.
