The Flesch-Kincaid readability tests are designed to assess the complexity of English texts. They provide a score that indicates how easy or difficult a passage is to read, based on factors like sentence length and word syllables. The two main formulas are the Flesch Reading Ease and the Flesch-Kincaid Grade Level.
The Flesch Reading Ease score ranges from 0 to 100, with higher scores indicating easier readability. The Flesch-Kincaid Grade Level translates the score into a U.S. school grade level, helping educators and writers tailor their content for specific audiences.
