ACT Writing: Rubric Scoring

The essay, or writing section, is the fifth section of the ACT and is completely optional for most students.

The score likely won't make or break your application on its own, but if a program you're applying to requires it, you'll need to have it done.

In the ACT Writing Section, you'll produce a developed, organized argumentative essay. The prompt presents a contested issue with some background information and multiple perspectives. Your job is to argue for a specific perspective using clear logic and relevant evidence.

Unlike the other four sections, your essay is not scored on a 1-36 scale. Here's how the scoring actually works.

📝 ACT Essay Scoring

Two separate graders will read your essay, not just one. This is similar to how AP Exam Free Response Questions are scored, and it helps ensure your score is fair and accurate.

Each grader evaluates your essay on four rubric categories:

• Ideas & Analysis
• Development & Support
• Organization
• Language Use & Conventions

Here's how the math works:

1. Each grader scores you from 1 to 6 on each of the four categories.
2. For each category, the two graders' scores are added together, giving you a category score from 2 to 12.
3. Your final writing score is the average of those four category scores, rounded to the nearest whole number, on a 2-12 scale.

The minimum score you can receive is a 2, and the maximum is a 12. Here's the rubric released by the ACT if you want to see exactly what graders use. Below, we'll walk through each of the four categories and what it takes to score well.

💡 Ideas & Analysis

The most important things the ACT rubric looks for in this category:

• Engaging with multiple perspectives from the prompt
• Writing a nuanced and precise thesis
• Establishing context for the issue and the different perspectives
• Examining implications, complexities, and tensions, in addition to values and assumptions

This category applies across your entire essay. Each body paragraph should engage with multiple perspectives, while a strong thesis is mainly the job of your introduction.

To score well here, clearly pick a perspective for your thesis and include arguments against other perspectives to strengthen your own position. You can work in counterarguments or concessions within each body paragraph to show you understand the complexities and tensions surrounding the issue.

This is the most all-encompassing part of the rubric, but with practice, it becomes manageable.

✏️ Development & Support

Graders want to see these qualities in your essay:

• Substantial evidence and development that broadens context and deepens insight
• An integrated line of reasoning with support that conveys your argument's significance
• Qualifications and complications that further strengthen your ideas and analysis

Development and support show up mainly in your body paragraphs, which make up the bulk of your essay. Your evidence should be as specific as possible and tie directly into your reasoning. Vague or generic examples won't cut it.

For a strong line of reasoning, open each body paragraph with a clear topic sentence that functions as a subclaim of your thesis. That topic sentence should align with everything else in the paragraph.

The final point here overlaps with Ideas & Analysis: bring up counterpoints that either disprove other perspectives or reinforce your chosen one. The topics the ACT selects are deliberately complex with no clear-cut "right" answer, so acknowledge that complexity through limitations, counterpoints, and qualifications.

🗂️ Organization

For the organization category, graders look for:

• A skillful organizational strategy
• A controlling idea or purpose that unifies your essay
• A logical progression of ideas that makes your argument more effective
• Transitions both within and between paragraphs that develop relationships between ideas

Organization is often the highest-scoring category because many students already write in a fairly structured way. Dedicating each body paragraph to a different perspective can get you up to a 4 out of 6 on its own. To push toward a 6, you need more intentional structure.

Make sure all your ideas link back to your thesis and that your organizational structure doesn't jump around. Ideas should build on each other and lead naturally from one to the next. Transitions help with this: use them at the start of paragraphs to signal shifts, and within paragraphs to connect pieces of evidence to your reasoning.

✍️ Language Use & Conventions

Your essay should demonstrate:

• Strong, effective use of language
• Skillful and precise word choice
• Varied and clear sentence structures
• Strategic choices in tone and voice
• Few errors in grammar, mechanics, and usage that don't impede understanding

This category checks whether your writing effectively communicates your argument. Vary your sentence structures using tools like semicolons, dependent clauses, and colons so your sentences don't all sound the same.

Tone matters too. Write formally but naturally. You don't need to force advanced vocabulary, but you also shouldn't write the way you text. Aim for an authoritative voice that sounds confident without being stiff.

Finally, proofread your essay as you go, and once more at the end if time allows. Just as speaking clearly and at sufficient volume makes a speaker more persuasive, writing clearly and avoiding grammar errors makes your essay more convincing. Graders shouldn't be distracted by mistakes when they're trying to follow your argument.
