Have you asked her about the testing experience? How experienced was the tester?
I have to agree that another test seems in order. I get how frustrating that is.
I don't think any kindergartener can read and progress through a book like RotK with understanding without being at least MG. (Likely more than that!) I mean, again, if she is really reading it-- more than a few pages here and there. (My daughter read a bit of Little Women in grade 2, but probably spent less than a hour with it in total, so I wouldn't say she's read it, YK? She was sort of toying with it, in part because she wanted to read an adult book.) I am not aware of a child in my DD's magnet gifted school class (99th% IQ required for admission) whose reading skills appear that advanced (meaning that I don't see a child who looks like he/she was reading Tolkien in K). A common level of proficiency for these children is Harry Potter and other high-level children's fantasy in 2nd grade, perhaps 1st grade for a few.
