Results
This tool gives a simple estimate from the numbers you enter. It does not check the test or the candidate.
How the numbers work
Two numbers, two questions.
Percentage
Score divided by total marks, times 100. It answers: how many marks did the candidate get out of the total?
Percentile rank
Count the group scores below the candidate's score. Add half of the group scores that are equal to it. Divide that number by the group size, then multiply by 100. It answers: how does the candidate compare with the group?
Reading the result
- A high percentile means the score is above most of the group.
- A low percentile means the score is below most of the group.
- The group must be a fair match. Small or mixed groups give less useful ranks.
- Do not use a percentile alone to make a decision.
Questions
Frequently asked questions
What is a percentile?
A percentile shows where a score sits within a group. A score at the 80th percentile is at or above about 80 out of every 100 scores in that group.
What is the difference between a percentile and a percentage?
A percentage is your score divided by the total marks. A percentile is your rank within a group of scores. You can score 60% and still be near the top of a group if the other scores were lower.
How are ties handled?
Each score that equals yours counts as half a score below yours. For example, if 10 scores are below yours and 4 scores are equal to yours, the count is 10 + (4 ÷ 2) = 12. That count is divided by the group size and multiplied by 100.
Does this tool store my data?
No. The tool runs in your browser. Nothing you type or paste is sent to AssessIQ or any other server, and nothing is saved.
