Thank you so much for your input! My son has Down syndrome, so we do take that into consideration, but he is in the third grade and is reading at a third grade level, possibly a bit higher. His spelling words are also third grade level, but he is currently working on the sixth grade sight word list, so vocabulary isn't necessarily the issue, as much as comprehension is. I do believe we have exhausted the "Henry and Mudge" series, where he was initially scoring 100%, and now is scoring 20%. I tried a Dragon Slayers Academy book with him, and we read the chapters together, reviewed each chapter afterwards, and then reviewed the chapter again before starting the next one. He KNEW this book inside and out, but only scored 20% on the test. It was at this point we adapted the test to do away with the multiple choice options and just let him answer the question. He would always pick the first answer on multiple choice.
Now my daughter, also in the third grade, had to bust her behind last year to even get the minimum amount of "points" to earn her reward of the year end AR carnival. She was terribly afraid of taking the tests and it showed. Once we convinced her that we didn't care if she failed each test as long as she tried her best, she soared! This year, she's blowning the points out of the ballpark and scoring 100% on all her tests. She's also reading at a sixth grade level, so I can't imagine what her book choices are going to be when she hits the fourth grade and she's exhausted the choices in the sixth grade level to "challenge" her.
I personally dislike AR because I believe it places a tremendous amount of pressure on the children to achieve a required point value, and I think burnout starts to move in each month after having to "achieve" a certain point total each month. I am easy to please. I think daily homework of reading a certain number of minutes each night is reasonable, without the pressure of scoring with AR points each month.
Anyway, thank you for explaining your views. I wish you were our librarian! You're far nicer than the ones we have in our neighborhood! And it was nice to be able to vent a bit to someone who understands what I'm talking about when I say "AR". Thanks!
