I understand that Flesch-Kincaid  in MS/ Word isn't perfect. But at my
organization we have a policy requiring that patient education materials
submitted for translation must be at a 6th grade or lower reading level in
English before they can be sent for translation.
The translation coordinator may get 5-10 documents in a day and
realistically  he can't hand score them all. But he can test them on-line.
When he finds a score above 6.8 (and it's usually 8-10th grade)  or so, he
send it to me for "English-to-English" translation. I bring the level down
and make the document more user-friendly. While I have taught several others
the basics of rewriting for easy to read, I am the main rewrite resource.
SAM is terrific and a goal.  But I can't really do it for all materials
because of  time constraints and volume. How do other people handle this?
I am so delighted to get the organizational buy-in to make things easy to
read. I feel like it is a whole other battle to hold out for testing
suitability for every individual piece unless/ until  we have resources to
offer to improve materials. For whole clumps of materials (e.g., for
diabetes and for asthma self-management), we can do SAM assessments.
In practice, I don't care so much that the on-line Flesch-Kincaid testing
max's out at 12th grade. I do care that we are able to do a quick screen and
have a number that we can show to the writers. It may not be a "real" number
but it does allow me to improve things that otherwise I  wouldn't have
access to.

Readability formulas are often a matter of personal preference.
Beware of the Flesch-Kincaid in Microsoft Word-it only scores up to grade
12. That's not the formula's fault-it's the fault of Microsoft programmers
who converted the formula into a software program. It's a flaw that
Microsoft has never acknowledged or fixed, even though several readability
researchers have contacted Microsoft about it. I believe that any research
relying on the Flesch-Kincaid in Microsoft Word-and there is a lot of it-may
come to the wrong conclusions.
Do not rely exclusively on readability formulas. They can be helpful, but
don't try to "write to the formula" just to get a lower grade level.
Evaluate materials using the Suitability Assessment of Materials (SAM)
developed by Doak, Doak, and Root in their 1996 book "Teaching Patients With
Low Literacy Skills."
Or consider using the cloze procedure to see how well people understand a
document. The cloze involves deleting every fifth word, and asking readers
to fill-in-the-blank. Sixty to 80% correct means that the document is OK,
40% - 60% correct means that the document needs better explanations, and
0% - 40% correct means that readers don't understand the document. It should
be reviewed and rewritten.
If you want to find out if people can understand a piece of writing, you
have to test it on a representative sample of readers. Readability formulas
will give you a rough estimate of how difficult the material is to
understand, but the grade levels should not be taken too seriously. After
all, some of these formulas were developed 30-60 years ago, and both reading
skills and reading materials have changed.
I don't know what it really means if something scores at a 10th grade
reading level-based on 10th grade reading skills in the 1950s.
I've used readability formulas extensively in my consulting, but I always
recommend other ways of evaluating written materials. Plus, depending on
what you're writing and who the audience is, I always look at things like
the number of words in a document, average sentence length, word commonness,
etc. as ways of giving my some ideas about information overload, working
memory limits, cognitive complexity, etc.
