Rounding rules

Prev Next

Rounding rules decide how Cirrus rounds the candidate's final percentage score. Use this article to pick a rule and understand its effect on grades and pass / fail outcomes.

Rounding is a tenant-wide setting. It affects every user. Changes only apply to schedules that have not yet started.

Where to find it

Open Admin > Global settings > General and find Rounding rules.

Global settings General tab with rounding rules

The four rules

  1. Round down: percentages are always rounded down to the next integer. 54.4, 54.5, and 54.8 all round to 54.
  2. Round up: percentages are always rounded up. 54.4, 54.5, and 54.8 all round to 55.
  3. Round up or down conditional: standard rounding. Decimals of .5 and above round up; below .5 round down. 54.4 rounds to 54; 54.5 and 54.8 round to 55.
  4. Use two decimals: the same three rounding behaviours, but applied to two decimal places. 54.485% becomes 54.48% (down), 54.49% (conditional), or 54.49% (up).

Effect on pass / fail

The pass mark is checked against the rounded percentage, not the raw percentage.

Example with pass mark 50% and Round up:

Raw % Rounded % Outcome
49.5 50 Pass
49.3 50 Pass
49.0 49 Fail

With Round down the same candidates would all fail until they hit 50.0% exactly.

Effect on grades

Assessment scales match the rounded percentage to a grade. Cirrus always uses the rounded percentage, not the raw score, to decide the grade.

The interaction with the scale boundaries is the main thing to check when changing rounding rules:

  • With Round up, a candidate hovering just below a grade boundary will be lifted into the higher grade.
  • With Round down, the same candidate stays in the lower grade.

Set the assessment scale percentages with the chosen rounding rule in mind, otherwise candidates near a boundary may land on the unexpected side.

Underlying score is unaffected

The raw points-based score is always calculated exactly. Rounding only applies to the final percentage, which then drives the grade and pass / fail. The candidate's raw points stay precise in the reports.
