When multiple teachers in a department teach Paper Towns, students can end up with very different expectations and grading standards. One teacher may emphasize analysis while another focuses on plot knowledge, and a student's grade can depend heavily on which classroom they are in. A common assessment helps address this by establishing shared goals and criteria. It also provides data that can inform department decisions.

Start by agreeing on the learning goals for the unit. Teachers should discuss what skills they want students to demonstrate, such as making a claim about character, using textual evidence, and analyzing narrative perspective. These goals shape the prompt and rubric. Without alignment on goals, a common assessment becomes a source of friction rather than a tool for improvement.

Next, draft the prompt and rubric collaboratively. Each teacher brings their experience with what works and what confuses students, and the final product is typically stronger than any individual draft. Aim for a prompt that is open enough to allow different interpretations but specific enough to be scored consistently. Pilot it with a small group before rolling it out.

Calibrating Scoring Across Teachers

Even with a shared rubric, teachers may interpret descriptors differently. Calibration sessions address this by having the team score a few sample essays independently and then discuss differences. These conversations often reveal hidden assumptions about what each level means. Over time, scores become more consistent and fair.

• Agree on the skills the assessment is meant to measure
• Write a shared prompt and a rubric with observable descriptors
• Score three to five anchor essays together before grading
• Record agreed examples of each performance level
• Revisit scoring after the first round and adjust the rubric

Using the Data Well

Once essays are scored, aggregate the results by criterion rather than just overall score. You may find that students perform well on thesis but struggle with analysis, which suggests where instruction should focus. Comparing results across classrooms can reveal strategies worth sharing. The goal is learning, not ranking teachers.

Avoid using the data punitively, since this can discourage honesty and collaboration. Frame the process as a collective effort to improve student writing. Teachers whose students excel in a particular area can share their methods in a department meeting. This builds a culture of professional learning.

Reducing the Grading Burden

A common assessment across many classes creates a large grading workload. Department leaders can ease this by providing consistent tools and structures, such as a shared comment bank and a standardized feedback format. Some departments use rubric-aligned AI grading tools to produce first-pass scores and feedback that teachers review. This saves time while ensuring all essays are evaluated against the same criteria.

Make sure teachers retain final authority over scores, and use the tool's output as a starting point. Reviewing a sample of AI-generated feedback together can help the department build trust and identify areas to adjust. Consistency in criteria benefits students and simplifies reporting. A thoughtful workflow can make a common assessment both rigorous and sustainable.

Sustaining the Practice

Common assessments work best as a recurring practice rather than a one-time event. After each cycle, hold a short meeting to reflect on what worked, what confused students, and what should change. Document the revisions so new teachers can benefit. Over years, the assessment becomes more refined and reliable.

Share results with administrators to demonstrate how the department uses data to improve instruction. Concrete evidence of student growth builds support for time and resources. A shared Paper Towns assessment can serve as a model for other units and grade levels. The collaboration it fosters is often as valuable as the data itself.
