Rolling out AI-assisted grading across a department works best when it begins with one unit and one rubric. A novel such as The Machine-Gunners is a good starting point because the assignments are familiar, the themes are consistent, and teachers already have strong opinions about what good essays look like. Starting small reveals what works before the approach is applied more widely.

The rubric is the foundation of the whole process, since the tool will apply whatever criteria it is given. Teachers should agree on the criteria and descriptors together, using language that reflects how they actually evaluate work. A rubric that is vague or inconsistent will produce vague or inconsistent feedback.

It is helpful to involve the teachers who will use the tool from the start. Those who feel ownership over the rubric are more likely to trust the results and to give honest feedback on how well it works. Early buy-in also reduces resistance during the pilot.

Steps for Building and Testing the Rubric

Begin with a draft rubric and test it against a set of sample essays that represent different quality levels. Compare the tool's scores with the scores teachers would give and note where they differ. Differences usually point to descriptors that need clearer wording or to criteria that overlap.

• Draft four or five criteria that reflect the skills taught in the unit.
• Write descriptors for each level using observable behaviors, not vague adjectives.
• Test the rubric on sample essays from strong, average, and weak work.
• Compare the results with teacher scores and revise unclear descriptors.
• Finalize the rubric and document it so every teacher uses the same version.

Running a Small Pilot

A pilot with a few classes allows you to check how the process works in practice before expanding. Track how long grading takes, how closely scores match teacher judgment, and how students respond to the feedback. Gathering this information makes it easier to decide whether to continue and how to adjust.

Teachers should review every set of results during the pilot, not just a sample. This helps identify patterns of error and builds familiarity with how the tool behaves. As confidence grows, the amount of review can be adjusted to fit the department's needs.

Scaling Across the Department

Once the pilot shows promising results, document the process for other teachers, including the final rubric, instructions for review, and tips for common issues. Offering a short training session can help colleagues feel comfortable. Sharing early successes, such as time saved or improved feedback quality, builds momentum.

Plan for ongoing review as well. Revisit the rubric at the end of each unit and adjust as needed based on what the data and teachers report. A continuous improvement mindset keeps the tool aligned with the department's goals and standards.
