The majority of readability formulas calculate the grade level of a text using syllable count, word count and sentence length. The exception are the Spache Readability Formula and the New Dale-Chall Readability Formula. Both of these formulas compare a graded word list with your text and then calculate a U.S. grade level based on the number of difficult words with average sentence length.
