Technically, because she scored *in* the 85th percentile, her score was somewhere in the lower 85% of scores, though it may have been very low. All that can be said with certainty is *at least* 15% of the test takers scored higher than she. To conclude that approximately 15% scored higher and approximately 85% scored lower than she did, it would have to have been said that she scored *at* the 85th percentile. The Wikipedia page on "percentile" elaborates on this subtle difference in phrasing.
