What Is Automated Readability Index?
The Automated Readability Index (ARI) is a metric used to determine the readability level of a text. It calculates a score that corresponds to a U.S. school grade level needed to comprehend the text. The formula considers the number of characters, words, and sentences in the text, making it particularly useful for assessing the complexity of technical documents and academic papers. Unlike other readability formulas that focus on syllables, the ARI’s reliance on character count provides a straightforward approach to readability analysis.
