Peter Kincaid and his team as a special project for the U.S. The Flesch- Kincaid Reading Grade Level scoring system was developed in 1975 by J. In the formula above, ASL = average sentence length (calculated as the number of words divided by the number of sentences), and ASW = average number of syllables per word (calculated as the number of syllables divided by the number of words). The specific formula for calculating the Flesch- Kincaid Grade Level score is: (0.39 × ASL) + (11.8 × ASW) - 15.59 school grade level for example, a score of 13.0 (as shown in the screenshot) means that the average freshman in college would be expected to understand the text.
