What does this tool do?
A score can improve in raw points or as a percentage of the first result. This calculator reports both views on the same maximum scale so the change is easy to interpret.
The Formula
Point gain = Second score − First score; Relative change = Gain ÷ First score × 100Frequently Asked Questions
Is a point gain or a percentage gain more useful?
Point gains show progress on the test’s own scale, while percentage gains show how large the change is relative to the starting score. Report both when the baseline varies.
What if the two tests had different maximums?
Convert both to percentages of their own maximum before comparing, or use a common scaled score. This calculator assumes one shared maximum.
