Flesch Reading EaseThe Flesch score uses the number of syllables and sentence lengths to determine the reading
ease of the sample.|
A Flesch score of 60 is taken to be plain English. A score in the range of 60-70 corresponds to 8th/9th grade English level. A score between 50 and 60 corresponds to a 10th/12th grade level. Below 30 is college graduate level. To give you a feel for what the different levels are like, most states require scores from 40 to 50 for insurance documents. :
Gunning Fog Scale LevelThe Gunning Fog scale is similar to the Flesch scale in that it uses syllable counts and sentence length. The scale uses the percentage of
'Foggy' words, those that contain 3 or more syllables.|
A fog score of 5 is readable, 10 is hard, 15 is difficult, and 20 is very difficult. :
|Flesch-Kincaid Grade LevelThe Flesch-Kincaid Grade Level heuristic indicates that the text can be read by the average student in the specified grade level. :|
|SMOG GradeThe SMOG (Simple Measure of Gobbledygook) grade is commonly used in health care. The score represents the number of years of education needed to understand a passage of writing. :|
SMOG score requires passage to be at least 30 sentences long.
|Dale–Chall scoreDale-Chall is one of the most accurate readability metrics.
Rather than rely on syllable counts to identify diffult words, Dale-Chall incorporates a list of 3,000 easy words which were
understood by 80% of fourth-grade students. The readability score is then computed based on how many words pressent in the passage are not in the list of easy words.
A score of 4.9 or lower indicates the passage is easily readable by the average 4th grade. Scores between 9.0 and 9.9 indicate the passage is at a college level of readability. :
About the Readability Analyzer
Readability metrics show the relative ease in which a written passage of text can be read and understood by others. They are heuristics typically based on sentence length, and word complexity. They are most commonly used in settings where clarity is crucial. For example, some states have requirements that legal documents and health care documents have minimum level of readability to ensure the intended audience can understand the documents. Keep in mind that readability is not a measure of writing quality.
This writing sample readability analyzer estimates the readability of a passage of text using the Flesch-Kincaid Reading Ease, Gunning Fog Index, Kincaide Grade Level, SMOG formula and Dale–Chall Score metrics. metrics.
