Flesch-Kincaid Grade Level is the educational counterpart of Flesch Reading Ease, developed for the US Navy in 1975.
The output corresponds to a US school grade level: a score of 8 means an 8th grader should be able to read the passage.
It is widely used by US government agencies and is required for many federal documents.
For general public communication target grade 7–8. For technical documentation, grade 10–12 is acceptable. Avoid going above 14 unless writing for specialists.
