When several teachers in a department teach the same novel, a common assessment can create consistency and generate useful data. A Thousand Splendid Suns is a good candidate because it is widely taught and offers clear opportunities to assess analysis, evidence, and writing. The challenge is designing an assessment that every teacher can use and score in the same way.

The first step is to agree on what the assessment measures. Departments often choose a small set of skills, such as developing a thesis, using textual evidence, and explaining reasoning, so that scoring stays focused. Trying to measure too many skills at once makes the rubric unwieldy and the results difficult to interpret.

Next, the prompt should be broad enough to allow students to choose different aspects of the novel while narrow enough to produce comparable work. A prompt asking how a character changes in response to hardship, for example, can be answered using several characters and scenes. This flexibility keeps the essays interesting to read and still allows consistent scoring.

Creating a Shared Rubric

A shared rubric should use language that all teachers understand in the same way. Descriptors should refer to observable features of the writing, and each level should be clearly distinguishable from the others. Drafting the rubric collaboratively helps teachers surface differences in their expectations before grading begins.

• A prompt that all students can answer using the same novel
• A rubric with three to five criteria and four performance levels
• Anchor papers that illustrate each level of performance
• A common administration window and set of conditions
• A shared process for reviewing and reporting results

Calibration Before Scoring

Calibration is the step that makes a common assessment trustworthy. Teachers independently score the same set of anchor papers and then compare their results. Differences prompt discussion about interpretation and lead to refinements in the rubric.

Once the department is calibrated, scoring can proceed with greater confidence. AI tools configured with the final rubric can serve as an additional check, flagging papers where the tool's score differs substantially from a teacher's. These flags guide a second look and improve reliability.

Using the Data

The value of a common assessment lies in what the department does with the results. Score distributions by criterion can reveal where students are strong and where they struggle. If many students lose points on explanation, for example, the department can plan shared instruction on commentary.

Teachers can also use the data to identify effective practices. If one classroom shows stronger results on evidence use, colleagues can learn what is happening there. This collaborative approach turns assessment into a tool for professional growth.

Sustaining the Practice

A common assessment should not become a burden. Keeping the rubric short, reusing anchor papers, and automating parts of the scoring process make it sustainable. A department that can run the assessment efficiently is more likely to continue it year after year.

Over time, a bank of anchor papers and refined rubrics becomes an institutional asset. New teachers can use these materials to learn the department's standards quickly. The result is more consistent grading and clearer expectations for students.
