Spell out or abbreviate academic degrees in your prose:

The requirements for the associate of arts degree have been updated on the department website.

The speaker holds a bachelor’s degree in Spanish, a master’s degree in secondary education, and a doctorate in performance studies.

All the applicants have MFAs in poetry or fiction.

In an entry for a work composed as part of a degree requirement, abbreviate the name of the degree:

Maragh, Shauna A. Glamour in Contemporary American Cinema. 2020. U of South Florida, Tampa, PhD dissertation. 

Academic degrees are abbreviated without periods after letters or spaces between letters (see MLA Handbook, appendix 1), and their abbreviations are made plural by the addition of the letter s (2.54).
