text: what does flesch - kincaid grade level mean?   the flesch-kincaid readability tests are readability tests designed to indicate how difficult a reading passage is to understand. there are two tests, the flesch-kincaid reading ease, and the flesch-kincaid grade level. although they supposedly use the same measures, just placed into a different scale, the results of the two tests do not always correlate (a text with a better score on the reading ease test over another text may end up with a worse score on the grade level test.)  flesch-kincaid grade level an obvious use for readability tests is in the field of education. the "flesch-kincaid grade level formula" translates the 0-100 score to a u.s. grade level, making it easier for teachers, parents, librarians, and others to judge the readability level of various books and texts.   the result is a number that corresponds with a grade level. for example, a score of 6.1 would indicate that the text is understandable by an average student in 6th grade.
