Is there a place to check grade-level or readability of text?

I am writing a document meant for a specific target audience - i.e., it shouldn’t be more difficult to comprehend than that written for a grade-7 student. Word has such a feature but I don’t see if in LibreOffice. Thx.

Have a look through the extensions that are language-related.
