College Essay Grader

The five things admissions officers consistently call out are a clear central message, an authentic voice, real reflection on what an experience taught you, specific concrete details, and a topic that genuinely matters to you. Polished grammar and a clean structure are expected.

CoGrader's Admission Rubric is built on the criteria admissions officers consistently say they look for, drawn from the Common App's published essay prompts and guidance and the National Association for College Admission Counseling's annual State of College Admission report.

Each admissions office uses its own internal guidance, but the criteria converge on a clear central message, an authentic voice, real reflection, specific concrete details, and a meaningful topic that reveals character. CoGrader's Admission Rubric scores against these five dimensions.

The Common App personal statement has a 650-word maximum. Most successful essays land between 500 and 650 words. Essays under 400 words usually feel underdeveloped, and essays at exactly 650 words sometimes feel padded. Aim for the length the story needs, not the maximum allowed.

The Common App personal statement is one essay of up to 650 words, written once and sent to every school on your list. You pick from seven prompts, and the focus is entirely on you. Supplemental essays are school-specific, usually 100 to 400 words, on prompts like "Why this school," "Why this major," diversity, challenge, or community. The focus shifts from you in isolation to you in relation to that particular school.

The current seven Common App prompts cover background or identity that defines you, lessons from failure, a time you challenged a belief, a problem you solved, an experience that triggered personal growth, a topic that captivates you, and an open prompt where you write about anything.

Using an AI grader for feedback on an essay you wrote is not cheating. Getting feedback on your writing, whether from a tutor, a teacher, a friend, or an AI tool, is a normal part of editing. Using AI to write the essay for you is a different question, and most colleges have explicit policies against it. CoGrader gives feedback on the essay you wrote, not a draft it generated.

Many college essay graders inflate scores to push paid upgrades. A working AI grader can reliably spot weak structure, vague language, missing reflection, and grammar issues. It cannot read an admissions officer's mind, so use it to find what needs fixing rather than to predict admit decisions. CoGrader's Admission Rubric ties every score to a named criterion, so you always see why a number is high or low.
