IB Rubric Design Checklist: Build Clear, Consistent Rubrics
A checklist for building IB rubrics that improve student writing and keep grading consistent across teachers.
A strong rubric makes expectations visible before students draft and makes feedback easier to apply after they submit. For IB writing, the rubric also needs to support moderation and consistent teacher judgment.
This checklist is designed for teacher-created rubrics and class-specific adaptations of IB criteria.
Rubric design checklist
- Limit the rubric to the criteria students can actually act on in the next draft.
- Write descriptors as observable behaviors, not vague praise.
- Separate argument quality from language control when both matter.
- Use student-friendly wording without losing the IB assessment language.
- Include one short example of what strong performance looks like.
- Test the rubric on two sample essays before using it with a full class.
Rubric clarity tests
- Student test: Can a student identify the next revision step from the descriptor?
- Teacher test: Would two teachers select the same band for a sample essay?
- Feedback test: Can each criterion generate a specific comment, not only a score?
Reusable descriptor language
- "The response uses evidence to support a clear line of reasoning."
- "Analysis explains the significance of evidence rather than repeating it."
- "Organization helps the reader follow the development of the argument."
- "Language is controlled enough that meaning remains clear throughout."
Rubric AI example output to review
A useful AI draft should translate a descriptor into a concrete next step, for example: "The student's evidence is relevant, but the comment should ask them to explain how the evidence supports the claim in paragraph two." Teachers can then adjust the descriptor or comment for their course context.
