Use the built-in spelling and grammar check in MS Word. When MS Word finishes checking
the spelling and grammar, it will display information about the reading level of the
document, including the grade level and reading ease score.
If your computer does not automatically display the readability statistics, you will
need to enable them. See NL 10605.115 for instructions on how to enable the Flesch-Kincaid readability test on your computer.
