Persepolis is a text that IB English teachers sometimes choose for study because it invites analysis of both language and visual form, along with the interplay of personal and political themes. It can support a range of assessments, from written tasks that explore an aspect of the text creatively to analytical essays and oral commentaries. Grading these tasks requires familiarity with the IB criteria and a consistent approach to applying them. Teachers who invest in understanding those criteria find that feedback becomes more precise.

IB assessment relies on criteria that describe levels of achievement across areas such as knowledge and understanding, analysis and evaluation, and organization and language. Unlike a simple rubric, these criteria use band descriptors that require judgment about where a piece of work best fits. That means teachers must read carefully and compare the work to the descriptors as a whole. Rushing the process leads to inconsistent marks.

A helpful first step is to review the official descriptors and turn them into language that students can use. Rewrite each band in plain terms and provide examples using Persepolis. For instance, a high-band analysis might describe how the artist's use of stark contrast creates tension between a child's innocence and the surrounding violence. Students benefit from seeing how abstract descriptors apply to a text they know well.

Applying Best-Fit Judgments Consistently

The best-fit approach means that an essay does not need to meet every descriptor in a band to be placed there. Teachers weigh strengths and weaknesses and choose the band that most closely matches the overall quality. This flexibility is valuable, but it can also produce variation between graders. Documenting your reasoning for each mark helps maintain consistency and prepares you for moderation.

• Read the essay through once without marking to get an overall impression
• Identify evidence for each criterion and note it briefly in the margin
• Choose the best-fit band for each criterion, then review your choices together
• Compare the work to an anchor essay you have previously marked at that level
• Write a short comment explaining the mark in language linked to the descriptors

Feedback That Prepares Students for External Assessment

Because IB work is eventually assessed externally, feedback should help students understand what examiners will look for. Comment on how well the student has demonstrated understanding of the text and its context, how thoroughly they analyze the author's choices, and how effectively they organize their response. Use the language of the criteria so students become familiar with it. This alignment reduces surprises later.

It is also useful to have students self-assess against the criteria before submitting. They can highlight where they believe they have met each descriptor and identify weaker areas. Comparing their self-assessment with your marks reveals gaps in understanding. This process builds the metacognitive skills that IB values.

Managing Workload in a Demanding Program

IB teachers often manage heavy marking loads alongside other program requirements. Efficient systems are essential. Standardized comment banks tied to the criteria, structured feedback templates, and moderation with colleagues all help. Where appropriate, AI-assisted tools can generate first-pass feedback aligned to the criteria, which teachers refine to reflect their professional judgment.

Be cautious about the limits of automated marking for high-stakes work. IB assessment depends on nuanced interpretation that tools may not capture fully, so teacher review is critical. Use technology to organize and accelerate your reading, not to replace your expertise. Combined with careful moderation, this approach can raise both efficiency and consistency.

Using Persepolis to Develop Transferable Skills

The skills students practice in analyzing Persepolis, such as reading visual and verbal evidence together, apply to other texts and media in the course. Encourage them to note techniques they can reuse, like analyzing framing or tone. Reflecting on how a single text can teach broader analytical strategies deepens their learning. It also helps them prepare for unseen texts in assessments.

Finally, keep a portfolio of marked work and feedback for each student. Reviewing it over time reveals patterns and progress that inform both instruction and future assessment. Students who see their development are more motivated and better prepared. A thoughtful approach to grading Persepolis tasks supports both immediate learning and long-term success.
