The Dale-Chall Readability Score was designed by literary researchers Edgar Dale and Jeanne Chall in 1948, then significantly
|
|
improved with a new formula in 1995.
|
|
</p>
|
|
<br />
|
|
<p>
|
|
Unlike other readability scales that attempt to measure complexity from word and sentence structure, the Dale-Chall formula
|
|
uses a list of 3,000 predetermined words that at least 80% of fourth graders are familiar with. Any words used that aren't
|
|
on this list are designated as potentially-difficult words.

A <strong>higher score</strong> on this scale indicates a document is <strong class="red-text">harder to understand</strong>.
