I looked up the drp scores online..with percentiles...she got 83...that is in the top 96-99 percentile for 9th grade...I think the upper grades require a higher percentage of comprehension...so, If she took the test in 9th grade she would be cut off at a lower point. But it isn't by a lot. She is in forth grade. The percentiles weren't there for 4th, but for fifth, a score of 60 (something) - 70 (something) was in the top 96 to 99 percentile. I think it is pretty good..I would guess 99.9, since it doesn't even have her numbers up there for the grade above hers...I also read that if someone got every single answer right on the whole test...they COULD get a 99...so, she didn't top it out with an 83...but the 99 would be for college level...hmmm...this stuff confuses me.
