The Grade School Writing Level

The most intellectual, highly educated people will appreciate and respond to appeals that are easy to read and comprehend. Our years of experience and research give us clues as to why this is so.
Flesch-Kincaid does grade level research. They use sentence length and the number of three-syllable words in a given document to calculate an appropriate grade level rating.

A reader who is tired or in a hurry, Flesch-Kincaid has found, will have trouble comprehending and be more likely to skim or just stop reading altogether.
