Chas McGill is the natural subject for a character essay in The Machine-Gunners, but the assignment is harder to grade than it looks. Students tend to list his traits, calling him brave, stubborn, and clever, without explaining how Westall shows those traits through action and dialogue. A strong essay treats Chas as a constructed character whose choices reveal something about a boy growing up under bombardment.

Before grading, decide whether the assignment asks for a trait analysis, a study of change over the novel, or a judgment about whether Chas is a hero. Each version rewards different evidence, and students who answer a different question than the one set will lose marks for reasons they cannot see. Writing the question on your rubric header keeps you from rewarding an essay for work it was never asked to do.

It also helps to settle how much credit you give for personal response. Some students will write movingly about how they would behave in Chas's place, which can be a genuine strength if it leads back to the text. If it replaces textual evidence entirely, treat it as a gap in analysis rather than as a bonus.

What Strong Character Analysis Looks Like

Strong essays connect a trait to a moment and then explain why the moment matters. For instance, a student might point out how Chas's relentless collecting of shrapnel and war souvenirs sets up his later need to possess the gun, then argue that Westall presents this as a boy trying to take hold of a frightening world. That chain of observation, evidence, and interpretation is what separates analysis from description.

• A claim about Chas that goes beyond a single adjective and offers a reason.
• At least two moments from different parts of the novel, not only the opening chapters.
• Comment on how other characters, including adults, react to Chas.
• Attention to how his motives shift, or fail to shift, as events escalate.
• A conclusion that says what Chas's story suggests about children in wartime.

Typical Weaknesses and How to Mark Them

The most common weakness is the unexplained quotation, where a line is dropped into the paragraph and left to speak for itself. Mark this by asking one question in the margin, such as "what does this word choice show?", and let the student find the connection. Over a few essays, students begin to supply that explanation without being prompted.

Another frequent weakness is treating Chas as consistently admirable or consistently foolish. Westall gives readers reasons to sympathize with him while also showing how his determination drags others into danger. Reward essays that hold both ideas at once, and encourage students who commit to one extreme to look for evidence that complicates their claim.

Writing Feedback That Pushes Thinking

Good feedback on a character essay asks the student to extend a thought they already started. If a paragraph observes that Chas ignores the warnings of the adults around him, a useful comment might ask what Westall gains by making those adults ineffective. This kind of question pushes the student toward the author's choices instead of simply telling them they need more analysis.

When class sizes are large, drafting these targeted comments for every essay is the most time-consuming part of the job. Rubric-driven AI feedback can produce a first draft of such comments for teacher review, which preserves the specificity students need while reducing the hours spent writing similar margin notes. Teachers can then add the personal observations that only someone who knows the class can offer.
