Twelve Years a Slave was published in 1853 with the help of an editor named David Wilson, and that fact has long raised questions for readers about whose voice they are hearing. It makes an unusually good topic for an argument essay because students can weigh real evidence on more than one side. Grading these papers well means rewarding the quality of the reasoning rather than the conclusion the student happens to reach.

Historians have generally found Northup's account to be reliable, in part because researchers were able to verify many of its people, places, and events through legal and public records. Students may also encounter the argument that an editor's hand shapes any dictated memoir, which raises fair questions about style and emphasis. A good assignment prompt presents both of these ideas so that students must weigh them rather than simply repeat one.

Before grading, decide whether your rubric will require students to take a side or permit a more balanced conclusion. Some teachers want a firm claim about how much Wilson's involvement affects the text's authority, while others accept a qualified position. Either approach works, but the rubric should say which one you expect so that students are not penalized for guessing wrong.

Evaluating claims, evidence, and counterarguments

The strongest essays on this topic separate what is known from what is inferred. A student might note that verifiable names and dates support the narrative's accuracy while acknowledging that the polished literary style probably reflects some editorial influence. That kind of careful distinction shows a maturity that deserves a high score, even if the essay reaches a conclusion that differs from the teacher's own.

• States a clear position on how far the editor's role affects the narrative's reliability
• Supports the position with specific evidence rather than general impressions about old books
• Distinguishes between verified facts and reasonable but unproven inferences
• Presents a strong counterargument and responds to it directly
• Uses measured language that avoids overstating what the evidence can prove

Scoring counterargument and rebuttal

Counterargument is where many otherwise capable students stumble. They either ignore the opposing view entirely or mention it in a single sentence and dismiss it without engagement. A strong paper states the opposing view in its most persuasive form, then explains specifically why the student still finds their own position more convincing.

When giving feedback on this element, point to the exact sentence where the student dismisses the other side too quickly. Ask what a thoughtful reader who disagreed would say in response, and encourage the writer to answer that objection in a full paragraph. This feedback tends to be repeated across many essays, which is where consistent rubric language and drafted comments can save real time.

Keeping the topic respectful and evidence-based

Because this subject concerns a real person who endured slavery, students should treat the question of authorship with care. The goal is to evaluate how a text was made, not to cast doubt on Northup's suffering or to suggest that the events did not happen. Setting that expectation at the start of the unit helps keep discussion and writing focused on evidence.

In feedback, distinguish between a student who questions a source rigorously and one who dismisses it without support. The first is doing exactly the kind of critical thinking the assignment invites, while the second is making a claim the evidence does not back up. Explaining that difference clearly protects both the integrity of the essay and the dignity of the historical subject.

Using student essays to improve the next assignment

After grading, look for the reasoning errors that appear most often across the class. If many students treat editorial involvement as proof of fabrication, the next lesson might compare how other historical memoirs were produced with help from editors or scribes. Targeted follow-up like this addresses the misconception directly instead of relying on individual margin comments to do the work.

Argument essays also make good candidates for revision, since the second draft is often much stronger than the first. Give students a short list of the rubric elements that most affected their score and ask them to revise one paragraph at a time. The process teaches that a strong argument is built through revision, which is a lesson that extends well beyond this single memoir.
