The tests were hand scored by the principal and I think he didn't do any caluculations other than the percentile...I could MAKE him do them, but I guess the district doesn't have enough money to buy the program that scores the tests, so I feel bad asking him to go back and do more after he gave up his Thanksgiving Vacation to score them...I was hoping I could figure out more, but I can't find anything online about the conversion. I really do think she should have scored higher than that. Her achievement so far has been consitantly in the 99%...hmmmm
