If your score is the 85th percentile this means that your score is above the 85% of the total population. If your score is in the 50th percentile this means that your score is above the 50% of the population.
The qualifying standard for the Presidential award is the 85th percentile. The 85th percentile is going to be different depending on the age and gernder. Jane was able to meet the standard but Matt wasn't. This means that the score (40 curlups) is above the 85% of the total number of scores for the population of 9 year old girls, but is is below the 85% if the total number of scores in the population of 12 year old boys. This means that the performance of Jane was better.
The standar for the National award for Matt is 40, which was his own score. This means that Matt's score corresponds to the 50th percentile. Again, it is evident that the performance of Jane was better because her score was above the 85th percentile.
