Grade Curve Calculator
Model a proposed curve without hiding the transformation: add fixed points, move the top score to a target, scale to a target top score or shift the mean.
Check the original class distribution first
Use Class Average & Grade Distribution before applying a curve so the baseline mean, spread and pass rate remain visible.

Formula
curve method transforms each raw score using a visible additive or multiplicative rule; results are not automatically capped at 100%
Example
If the highest score is 92 and “add so top = 100” is selected, 8 points are added to every entered score.
Useful for
- Comparing possible grading curves
- Teacher score adjustment planning
- Testing target-mean or target-top methods
Questions
Does Lynara recommend a curve method?
No. The tool shows the arithmetic effect of the method you choose.
Are curved scores capped at 100%?
No. Lynara leaves transformed values visible so the effect of the rule is not hidden; apply a cap only if your actual policy requires it.
