Already on Mots Justes, an example has surfaced of just how evolutionary grammar and punctuation can be. Below you’ll see that I used no periods in the abbreviation of my academic degree.
Now, neither Diana Hacker’s Bedford Handbook for Writers nor The Associated Press Stylebook addresses this issue directly, but in both, entries discussing how to use titles use periods:
Annlee Ellingson, B.A.
However, the most recent edition of The Chicago Manual of Style has this to say:
In conservative practice, periods are added to abbreviations of all academic degrees (B.A., D.D.S., etc.). Chicago now recommends omitting them unless they are required for tradition or consistency. (Italics are mine.)
Indeed, the no-period style seems to have been widely adopted: as I close in on my master’s (on this possessive apostrophe, the style guides agree), I can’t recall ever seeing “M.F.A.” or, in my case, “M.P.W.” (Master of Professional Writing). So, in a few months, this will be my signature:
Annlee Ellingson, MPW
Still, if you’re writing for a newspaper, stick with the traditional period-based abbreviation. (Actually, AP advises avoiding the issue altogether by phrasing it like this: “Annlee Ellingson, who has a master’s in professional writing …”)
In general—but especially when dealing with the more malleable “rules” of grammar and punctuation—the key is to be consistent. Pick a style and stick with it.
