How Students Can Use Readability Scores

Check your essay's reading level

Readability scores give you an objective measure of how complex your writing is. If your score is much higher or lower than your assignment's target level, you can make adjustments before submitting.

Identify problem sentences

The Breakdown panel shows your average sentence length and flags when sentences are too long. Long, tangled sentences are one of the most common writing problems in student essays — and one of the easiest to fix.

Improve clarity without losing depth

Good academic writing doesn't have to be hard to read. You can use precise, sophisticated vocabulary while still writing clear, well-structured sentences. A lower grade-level score doesn't mean worse writing — it often means better writing.

Readability Targets by Assignment Type

High school essays

High school writing typically targets Grade 9–11 on the Flesch-Kincaid scale. Focus on clear argument structure and varied sentence length rather than trying to sound complex.

College papers

College-level writing generally falls between Grade 12 and Grade 14. Academic papers require precise vocabulary and well-constructed arguments — but clarity is still valued over unnecessary complexity.

Creative writing

Creative writing has no single readability target. Most published fiction sits between Grade 6 and Grade 9, regardless of how sophisticated the themes are. Simple sentences and strong word choice outperform complex sentence structures.

Writing Tips for Better Readability

One idea per sentence

The most common cause of hard-to-read sentences is trying to pack too many ideas into one. If a sentence contains more than one main idea, split it into two. Your reader will follow your argument more easily.

Cut unnecessary words

"In order to" can almost always be replaced with "to." "Due to the fact that" means "because." Trimming filler phrases shortens sentences, lowers your grade-level score, and makes your writing sharper.

Read your writing out loud

If you stumble while reading a sentence aloud, your reader will stumble too. Reading aloud is one of the most effective ways to catch overly complex sentences before your teacher does.
