Use an apostrophe in bachelor’s degree, a master’s, etc., but there is no possessive in Bachelor of Arts or Master of Science.
The exact degree is uppercase, as is the subject. This is an exception to AP.
Example: Master of Fine Arts in Interactive Media, Master of Science in Leadership, Master of Arts in Public Administration and Master of Arts in International Administration.
Whenever possible, use the generic version of the degree name: a master’s in leadership or a master’s degree in leadership. But a Master of Science in Leadership.
Also an exception to AP Style: Abbreviations of degrees, certifications and licensures follow the first reference of all names, and do not contain periods. Typically, a terminal academic degree is the only one listed, but the source’s preference will determine:
Example: Carlos Roberto Jaén, MD, PhD, FAAFP, professor and chairman of family and community medicine
Academic degrees come before licensures: John Doe, DPT, PT.
Ricky Joseph, PhD, OTR (Co-PI)
School of Nursing Dean Sonya Renae Hardin, PhD, MBA/MHA, CCRN, NA-C, FAAN
If possible, try to limit credentials to the most relevant terminal degree and one preferred certification or license.
