Peter Brownrigg is an appealing subject for a character analysis essay because Geoffrey Trease gives him real distance to travel, both geographically and personally. He begins as a country boy facing trouble with a powerful local landowner and ends up involved in a plot that reaches the Queen's own safety. A strong essay tracks that growth with evidence instead of simply announcing that Peter becomes braver.

Most student essays on Peter fall into one of two traps: they list personality adjectives such as brave, clever, and loyal, or they retell the plot in order with a sentence of opinion at the end. Neither approach demonstrates the thinking a character analysis is meant to assess. A rubric needs to reward students who connect a specific action to a specific trait and then explain what that connection reveals.

Designing that rubric starts with deciding what you want students to be able to do with a character. In a seventh grade classroom the goal might be to trace one trait across three moments in the book, while an eighth grade class might be asked to explain how Peter's perspective shapes what readers understand about Elizabethan London. The rubric language should match whichever skill the assignment actually targets.

Criteria That Reward Real Analysis

The most useful criterion for character essays is the link between action and trait. A student who writes that Peter is resourceful because he improvises a way to survive among the players, and then explains what that improvisation says about how he has adapted, is doing genuine analysis. Scoring that link separately from the quality of the writing prevents a polished but shallow essay from earning a top mark.

• Trait claim: names a specific, arguable quality of Peter rather than a generic adjective.
• Textual support: uses at least two moments from different parts of the story.
• Change over time: shows how Peter's attitude or abilities develop from the opening chapters onward.
• Interpretation: explains what Peter's choices reveal about courage, loyalty, or growing up.
• Writing quality: sentences are clear enough that the argument can be followed without rereading.

Scoring Change Over Time

Change over time is the hardest criterion for middle school writers because it requires them to hold the beginning and the end of the book in mind at once. Strong responses compare an early scene, such as Peter's first nervous encounters in an unfamiliar city, with a later scene where he acts with more confidence. Weaker responses simply say that Peter "learns a lot" without pointing to either end of the arc.

To score this fairly, many teachers use a three-step check: does the essay name a starting point, name an ending point, and explain the bridge between them? An essay that does all three can earn full credit even if its prose is simple. An essay that only names an ending point, however eloquent, has not yet shown change.

Feedback That Moves Students Forward

Feedback on character essays is most effective when it points to one move the student can make in the next draft. Telling a student that "your evidence shows Peter is quick thinking, but you have not said why that matters to the story" gives them a clear task. General praise or a list of five corrections tends to overwhelm students and leaves them unsure where to start.

AI-assisted tools can help generate this kind of targeted comment quickly when they are given the rubric language directly. The teacher can then check that the suggested comment names the correct trait, matches the quoted evidence, and fits the student's level. This keeps the feedback personal while removing the repetitive typing that slows grading down.

Common Mistakes to Watch For

One frequent mistake is confusing Peter's circumstances with his character. Students may write that Peter is brave because he travels to London, when the journey was largely forced on him by trouble at home. A good rubric note encourages them to look for moments where Peter makes a real choice rather than simply reacts to events around him.

Another common issue is treating Peter in isolation from the characters around him. His friendship with Kit and his dealings with the acting company shape how readers judge his choices, so strong essays often use those relationships as evidence. Reminding students of this in a pre-writing mini lesson reduces the number of flat, one-dimensional character essays you will need to grade.
