I think AR was good for my kids early-on (maybe until about 4th grade). It made them read or they didn't make their goals. After 3rd grade, their reading levels were too high, so that the books were either gigantic (and they'd forget a lot by the time they finished & tried to test), old-fashioned/difficult to read,inappropriate, etc. It took the joy out of reading. Then the goals became drudgery. One of the boys favorite thing about going to the charter middle school is that they DON'T have AR. The public schools here have AR through 8th grade.
