A percentile grade tells you what share of a group scored below you. With the midpoint rule it is (scores below + half of ties) ÷ group size × 100. In a quiz of 60, 70, 80, 80 and 90, a score of 80 has two below and two equal, so it sits at the 60th percentile.
Teachers, tutors and students often have the raw marks for a class but want to know where one result stands in that group rather than as a percentage of the maximum. A 72% can be near the top on a hard paper and below the middle on an easy one. Type each score in the group as a row, enter the score you want to place, and choose how ties are counted. The tool returns the percentile rank, the position counted from the highest score, how many results fell below or matched, plus the group mean and median, and a sorted table of the whole set. One limit: a percentile from a small class moves in big jumps, so with ten students each place is worth ten points and the figure is not comparable with a national norm table.
Type one score per row and use Add score for more rows; include your own score in the list if it belongs to the group.
This is the result being placed against the group.
Count ties as half matches most test norms; strictly below gives the plain share of lower scores.
Check the percentile, position and the sorted table showing which scores sit above or below yours.
Result Percentile rank: 60
Position (highest first): 2 of 5
Scores below yours: 2
Scores equal to yours: 2
Group mean: 76
Group median: 80
Two scores sit below 80 and two equal it, so half the ties count and the rank is the 60th percentile.
Result Percentile rank: 40
Position (highest first): 2 of 5
Scores below yours: 2
Scores equal to yours: 2
Group mean: 76
Group median: 80
Counting only lower scores, 2 of 5 gives the 40th percentile, so the choice of rule moves the answer by 20 points here.
PR = (B + 0.5 × E) ÷ N × 100, or PR = B ÷ N × 100 with the strictly-below rule
PRBENThe midpoint rule treats a tied score as sitting halfway through its tie, which is how percentile ranks in norm tables are usually built. The strictly-below rule ignores ties and reports only the share of lower scores, so it is always equal to or lower than the midpoint value. Position is counted from the top: one plus the number of higher scores.
No. A percentage score compares your marks with the maximum possible. A percentile rank compares you with the other people who took the test. Scoring 85% could be the 30th percentile if most of the class scored higher.
When several people share your score, the midpoint rule counts half of them as below you and the strictly-below rule counts none. In the five-score example with two 80s, that is the difference between the 60th and the 40th percentile. Without ties, the gap is half of one score's share.
Yes, if you sat the same test as the group. Your score then counts as one of the ties under the midpoint rule. If you are comparing an outside result against a reference group, leave it out; the tool notes when your score is not found in the list.
Under the midpoint rule the top scorer gets less than 100 because their own score counts as half. In a class of ten, a unique top score sits at the 95th percentile. With the strictly-below rule the top score in ten reaches 90.
Those are calculated the same way but against a large national norm group, often several years of test takers, and published as a table. This tool only ranks against the scores you enter, so it answers where you stand in your class, not nationally.
They show the centre of the group. If your score is above the median your percentile will be above 50 under either rule; the mean can be pulled by a few very low or high scores, so the median is the better comparison in small classes.
