Gemini now writes the Classroom rubric. Start with what the student must show

An AI can draft a rubric in seconds. The hard part is deciding what counts as evidence.

Google is moving that work closer to the assignment itself. Starting August 5, teachers can generate an editable rubric directly in the Google Classroom assignment workflow. Gemini uses the assignment context as its starting point. That removes some clicking, but the bigger gain comes when teachers spend their time on the quality of the criteria instead of building boxes.

This article gives you a 40-minute test using a real assignment. The result should be a rubric students can understand, teachers can apply consistently, and colleagues can review before teaching begins.

What Google Classroom changed on August 5

A rubric describes the parts of a piece of work that will be assessed and what different levels of quality look like. It can use points or work without them.

Google Classroom already supported manually created rubrics, reused rubrics, and file conversion with Gemini. The new route starts inside the current assignment. Under Rubric, the teacher can choose Generate new, enter the grade and performance levels, add instructions or a file, and ask Gemini to propose criteria. The proposal remains editable before it is saved.

Google now describes three routes that sit alongside each other:

• generate a new Classroom-ready rubric from the assignment;
• convert an existing rubric from Drive or a local file;
• draft a rubric in the Gemini tab and export it to Google Docs or Sheets.

The rollout began on August 5, 2026 and should take one to three days across both Rapid Release and Scheduled Release domains. It is available in Education Fundamentals, Education Standard, and Education Plus. Google also says this particular new feature is limited to users over 18 and is on by default when Gemini in Classroom is enabled.

Move the time from formatting to assessment decisions

AI can quickly fill four criteria with four levels. That does not mean the rubric is ready. First drafts can confuse quality with effort, add requirements that never appeared in the assignment, or use phrases such as "well developed" without showing what well developed work looks like.

Let the feature handle the structure while keeping the professional decisions visible. The teacher still needs to decide:

• what knowledge or skill the assignment should provide evidence for;
• which part of the student's product demonstrates that knowledge or skill;
• what distinguishes two adjacent levels;
• whether students can understand the criteria before submitting;
• how the rubric will be used for feedback and assessment.

Google lets the teacher edit criteria, descriptions, levels, and points before saving. Once grading has started, the rubric can no longer be edited or deleted. The review therefore belongs before publication, not after the first submissions arrive.

A 40-minute test for a better rubric

Choose an assignment you already know well. A report, oral presentation, lab, problem-solving task, or practical demonstration will work. Do not begin with an entire course. A bounded assignment makes it easier to see whether Gemini has understood the assessment.

Minutes 0–8: write an evidence note

Write five lines before using AI:

1. Learning goal: What should the student know or be able to do after the assignment?
2. Student product: What will the student submit or demonstrate?
3. Visible evidence: Which parts of that product demonstrate the intended learning?
4. Common misconceptions: What can look correct while revealing a gap in understanding?
5. Outside the assessment: What should not affect the level, such as font choice, personality, or speed of work?

That last line is unusually useful. It stops a polished AI rubric from rewarding something the assignment was never meant to measure.

Minutes 8–15: check the assignment itself

Read the assignment instructions next to your evidence note. If an important skill is missing from the instructions, it should not quietly appear in the rubric. Either revise the assignment or remove the criterion.

Mark words that can mean different things to different students: "detailed", "creative", "relevant", or "well structured". Replace them with evidence someone can observe. "Uses two sources and explains why they give different accounts" is easier to understand and assess than "shows good source criticism".

Minutes 15–25: generate the first draft in Classroom

Open the assignment on a computer and go to Rubric → Generate new. Enter the grade or level and the number of performance levels you want. Add the assignment instructions and your evidence note, then ask Gemini to generate the criteria.

Do not save immediately. Read the proposal as a working draft. Look for new requirements, overlapping criteria, and levels that differ only through stronger adjectives.

Minutes 25–35: pressure-test the levels

Imagine a student response that sits between two levels. Can you point to words or features in the response that determine where it belongs? If two teachers could reasonably choose different levels, the description needs more observable evidence.

Check the balance as well. A language criterion can otherwise carry the same weight as the entire subject-matter argument even when language form is not the main learning goal. Change the points or use an unscored rubric if that fits the assignment better.

Minutes 35–40: run the student reading test

Read the lowest and highest levels as if you were seeing the assignment for the first time. A student should be able to answer two questions:

• What must be present in my work?
• What does the next stronger level look like?

If the answer requires a teacher to translate the rubric aloud, it is not finished. Rewrite the least clear row before saving.

Copy-ready rubric brief

Paste this template into the instruction field when you generate a new rubric. You can also use it in the Gemini tab when you want to develop the assessment logic before creating the assignment.

Help me draft a Google Classroom rubric.

Subject and level: [subject, grade, or course]
Assignment: [short description]
Student product: [report, presentation, lab, demonstration, or other]
Learning goal: [what the student should know or be able to do]

Evidence that should be visible in the student's work:
- [evidence 1]
- [evidence 2]
- [evidence 3]

Common misconceptions the rubric should distinguish from correct understanding:
- [misconception 1]
- [misconception 2]

Do not assess:
- [for example personality, speed of work, or formatting rules not stated in the assignment]

Create [number] criteria with [number] performance levels. Describe each level through observable evidence in the student's product. Use language students at this level can understand. Make adjacent levels meaningfully different. Do not add requirements that are absent from the assignment. Do not assess effort, compliance, or assumed intent.

Suggest points and weighting, but briefly explain the reasoning. Start with a section titled "Teacher decisions" and list missing information or choices AI should not make. Then write the rubric draft.

The prompt will not force a perfect rubric into existence. It exposes gaps before Gemini fills them with a confident assumption.

The student Gemini tab makes clear assignments more important

Google published a related Classroom update on August 4. Starting August 10 on the web and August 17 in the mobile apps, the Gemini tab in Classroom will become available to students of all ages when their administrator has granted the relevant access.

Students will be able to select a class and assignment when they use starter prompts. Gemini then pulls context from the assignment title, instructions, and course materials to create practice questions, flashcards, a study guide, or similar learning support. Google does not say that the new rubric automatically becomes part of this context. The assignment title, instructions, and materials therefore need to work on their own. Unclear instructions give both the student and the AI weaker material to work with.

The rollout covers Education Fundamentals, Standard, and Plus. Administrators control access through organizational units and the settings for Gemini in Classroom, the Gemini app, and Gemini Notebook. A school can therefore introduce the feature to a focused group before a wider rollout.

Language, accounts, and review in a Nordic school

Google's help page says Gemini in Classroom is available in all Classroom-supported languages where the Gemini app is supported. The same page marks some embedded Classroom features as English-only. The launch page for the new rubric generator does not state a separate language restriction. Check what is visible in your domain and test one Swedish, Danish, Norwegian, or Finnish assignment before you make it a shared routine.

Use a managed school account and the organizational unit selected for the test. A rubric draft normally needs assignment information, not personal data about individual students. Have a teacher approve the rubric before assigning the work, then save a reviewed example that colleagues can reuse.

Try it on an assignment that already exists

Do not create a new AI lesson for the test. Take the next assignment you already plan to use and compare two things: the time required to build the rubric and the number of phrases that need rewriting after a colleague reviews it.

After two or three assignments, you will have better evidence than a general discussion about AI in schools. You will see which instructions Gemini interprets well, which criteria repeatedly become vague, and which decisions belong in a local template. If several teachers will share the method, it becomes a focused Tool Forge project: one common brief, one review routine, and an approved rubric library instead of another disconnected AI experiment.
