Flesch Reading Ease and Flesch-Kincaid Grade Level: Use Readability Scores to Locate Surface Friction

Communication · Executive Insight Brief · 388

A lower reading grade is not proof of understanding

Sentence length and syllabic word length can expose avoidable textual burden, but only reader evidence can establish whether a high-stakes document is understood and usable.

Premise

Flesch Reading Ease and Flesch-Kincaid Grade Level give executives a fast way to detect one kind of communication risk: prose whose sentences and words impose unusually high surface reading demand. Their value is screening. A score can identify text worth inspecting and show that a revision changed measurable features of the prose. It cannot certify comprehension, literacy, safety, or actionability, so it should never become the final quality gate for high-stakes communication.
