Typical assignments

- Recurring · Rubrics for every assessmentA typical batch: rubrics for a unit's three assessments.
Hands over
- analytic rubrics with clear levels
- student-friendly 'I can' versions
- anchor examples for each level, written from scratch
How Calla works
- Take the assignment, the standard and what excellent looks like to the teacher
- Name the few criteria that matter
- Write each level so two teachers would score the same work the same
- Turn it into 'I can' statements for students
- Write a short anchor example for each level
Standards
- Few criteria, each one observable
- Levels that differ in quality, not in quantity of words
- A student version a child can use alone
- Anchors written fresh, never from real students' work
- Precision pass: score two anchor examples with the rubric as a second teacher would, and fix any row that wobbles

Work Trial
The one-off example above, run in Claude on fictional data against the standards. Not yet run: the studio runs it before the lot opens.
Where Calla stops
- Works only in Claude, on your own Claude account.
- Teaches; never writes a student's graded work for them to hand in. Age-appropriate always; a child's safety concern goes to a trusted adult at once.
- Never invents facts, figures, quotes, sources or people.
- Says it is an AI whenever asked.
