Rubric Library

Authoring rubrics, score levels, holistic vs shared scale, and immutability.

The Rubric Library

Rubrics in the menu opens your library. Rubrics are owned by you, not by a class, so one rubric can be reused across many classes and evaluations.

Authoring a rubric

New rubric opens the table editor. Each row is a criterion with:

  • a title (free text, for example Contribution to the group's output)
  • an optional description shown to students as guidance
  • a set of score levels: the values a student can pick and what each one means

A criterion row only counts once every required field is filled in.

Shared scale vs holistic

  • Shared scale: every criterion uses the same point range (for example 1 to 5). The General Average is a straight average across criteria.
  • Holistic: each criterion has its own point range. There is nothing to average across differently scaled criteria, so the General Average becomes a point total: the sum of each criterion’s earned mean over the sum of each criterion’s maximum, expressed as a percentage. See Reports & Results for the exact formula.

Pick the style that matches how you grade. You cannot mix the two within one rubric.

Duplicating

Use Duplicate to start a new rubric from an existing one. This is also how you make a correction to a rubric that is already in use. You never edit one in place once an evaluation has locked it (see below).

Immutability

A rubric can be edited freely until an evaluation that uses it is activated. At activation the evaluation stores its own snapshot of the rubric, and that snapshot is read-only for the life of the evaluation. Editing the library rubric afterward has no effect on evaluations already running against the old version.

If you find a mistake in a rubric mid-evaluation, the fix is: duplicate the rubric, correct the copy, and use the copy for a new evaluation. The flawed evaluation’s snapshot stays as it was.
