What form field labels tend to be used for pre-nominal and post-nominal academic titles in forms? Is e.g. "prenominal academic degree" used or is that too formal?
I've often seen this labeled "Title" / "Name" / "Suffix" where Title and Suffix are collected via a select menu of predefined options.
For example, American Airlines includes a Title select menu containing MR., MRS., MS., MISS, MX., DR., and MASTER, as well as a Suffix select menu containing JR., SR., M.D., II, III, IV, V, and PH.D..
To address the specific case of only seeking academic titles rather than others that show other modifiers as well, it looks like there are a few terms for these.
There are a couple entries in Wikipedia for prenominal and postnominal letters. I'm seeing usage for both terms spelled with and without the hyphen, and both terms phrased as *-nominal letters, titles, or simply as a noun (e.g. post-nominals).
My assumption is that those who carry these modifiers will likely be familiar with these terms and would probably not be confused by seeing "Prenominal title" and "Post-nominals" (my impression of the two most common embodiments, but take your pick). If you worry that these terms may still cause your users pause, you can add a tooltip description next to the label as to what is intended for each blank, with examples.
