Pregnancy and caregiving run through several chapters of Because of Sex, from Ida Phillips's challenge to a policy about mothers of young children to Peggy Young's fight over light duty at UPS. Comparing these cases lets students see how legal reasoning about the same social issue evolved over decades. Comparative essays are demanding, though, since students must analyze each case and then explain how they relate. Graders need criteria that reward the comparison, not just the individual summaries.

The most common failure is the two-halves essay, in which a student writes about the first case for half the paper and the second for the rest. The conclusion may mention that the cases are similar or different, but the body never does the work of comparing them. This structure is easy to write and tempting to accept, yet it does not demonstrate comparative thinking. A rubric should state explicitly that the comparison must appear throughout the essay.

Prompts can help by naming the dimensions of comparison. For example, students might be asked to compare how the Court defined unfair treatment, what evidence each plaintiff needed, and what remedies were available. These guideposts give the essay a structure and make grading more objective. Without them, students may choose points of comparison that are superficial or inconsistent.

Look for point-by-point organization

A comparative essay organized by point, rather than by case, forces the student to weigh the cases against each other in every paragraph. A paragraph on legal standards would discuss both Phillips and Young, noting how the Court treated employer justifications in each. This approach shows the student is actively comparing and produces sharper analysis. It also makes the grader's job easier, since each paragraph can be evaluated against a specific comparison point.

• A thesis that makes a claim about the relationship between the cases, not just a list
• Accurate summaries of each case limited to the facts needed for comparison
• Paragraphs organized around points of comparison rather than one case at a time
• Analysis of why the differences or similarities matter for workers and employers
• A conclusion that extends the comparison into a broader insight

Reward insight, not just similarity and difference

Listing similarities and differences is a starting point, but strong essays go further and explain what those patterns reveal. A student might argue that Newport News and Young show courts repeatedly relying on statutory text to extend protection while leaving gaps that later litigation had to fill. That claim is an interpretation, supported by comparing the reasoning in each case. Papers that reach this level deserve recognition in the top rubric band.

Feedback for weaker essays can suggest a simple revision exercise. Ask the student to identify the single most important similarity or difference and rewrite the thesis around it. This pushes them to commit to an interpretation and usually leads to a more coherent paper. Even a modest shift from description to claim can raise the quality noticeably.

Handle accuracy carefully

Comparative essays carry a risk of factual blending, where details from one case leak into another. A student might attribute the reasoning in Newport News to Young or confuse the plaintiffs in different decisions. Because the cases share themes, it is easy to make such mistakes. Graders should check the factual basis of each comparison, since an inaccurate premise undermines the analysis built on it.

Encourage students to include a short reference table or notes in their prewriting, listing the key facts and holding for each case. This simple tool reduces errors and clarifies thinking. You might require it as a low-stakes submission before the essay. It also provides an early checkpoint where you can correct misunderstandings.

Scale up grading without losing nuance

Comparative essays are time-intensive to grade, since each paper must be read for both accuracy and structure. A rubric with clear levels for the comparison criterion helps graders decide quickly whether an essay is merely descriptive or genuinely comparative. Consistent application matters, particularly when multiple graders are involved. Norming on a few sample essays before grading begins is a reliable way to align expectations.

AI-assisted grading can support this by checking each essay against the comparison criteria and drafting comments that point to where the structure breaks down. For example, it might note that the essay never connects its discussion of the two cases until the final paragraph. The instructor reviews and refines these observations, adding nuance about the legal content. Students receive more specific guidance, and graders spend less time repeating the same structural advice.
