How to Use Rubric Generator
- 1Describe the assignment — 'Persuasive essay', 'Science lab report', 'Group presentation'.
- 2Set the grade level so the performance descriptors match what's reasonable to expect.
- 3Choose a grading scale: 4-point, 5-point or percentage out of 100.
- 4Optionally list your own criteria — 'content accuracy, organization, grammar, use of evidence, creativity'. Leave it blank and appropriate criteria are chosen for the assignment type.
- 5Click 'Generate Rubric'. You get a rubric laid out as a table with a descriptor at every level and a scoring guide beneath it.
Frequently Asked Questions
Which grading scale should I use?
A 4-point scale forces a decision either side of the midpoint, which is why many schools prefer it. A 5-point scale allows a genuine middle. Percentage suits assignments that roll into a numeric grade. Match whatever your school already uses, since a rubric that doesn't convert cleanly creates work at reporting time.
Should I supply my own criteria?
If you have them, yes — a rubric that matches the criteria you actually taught to is more defensible than one built from an assignment name. If you leave it blank, the criteria chosen will be sensible for the assignment type but generic to it.
Are the descriptors specific enough to share with students?
They're written to be measurable and observable rather than vague, which is the point of a rubric — 'uses three pieces of evidence, each explained' can be checked, 'good use of evidence' cannot. Read them through for your context before publishing, especially the top band.
Can I use this for group work?
Yes — describe it as a group presentation or group project and the criteria will reflect that. Consider adding a criterion for individual contribution yourself, since that's the part group rubrics most often miss and the part students most often dispute.
Will it match my department's rubric template?
It produces a text table you can paste into your own template. Row labels and level names may need renaming to match your house format, which is a quicker edit than writing descriptors from scratch.
About Rubric Generator
A good rubric does two jobs: it tells students what's expected before they start, and it makes your marking consistent and defensible afterwards. Both depend on descriptors that are specific enough to check. The Rubric Generator produces a full table — every criterion described at every level — for an assignment and grade level you specify.
Supplying your own criteria is worth the extra thirty seconds. A rubric built from 'persuasive essay' assesses persuasive essays in general; one built from 'content accuracy, organization, use of evidence, grammar' assesses the things you taught and told students to focus on, which is what makes it fair.
Descriptors are written to be observable rather than evaluative. The difference matters when a student queries a grade: 'uses three pieces of evidence, each explained' is a claim you can point at in their work, where 'good use of evidence' is a judgement you have to defend in the abstract.
The output comes as a text table, so pasting it into your school's template and renaming the bands is usually all that's needed. Read the top band carefully before you publish it — that's the one students aim at, and a vague top band undoes the rest.
