                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>
                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>.
