When to capitalize? This handy guide can help

This post outlines the basic, most common guidelines for capitalization, with examples.

Academic degrees: Lowercase—”bachelor’s degree”; capitalize entirety of most abbreviations (with a few exceptions, including PhD and DLitt)

Academic disciplines: Capitalize only proper names—”Asian studies” (except as part of a full name of an entity (“the School of Business,” “the Department of Philosophy,” “the Commission on the Liberal Arts,” etc.)

Acronyms and initialisms: Capitalize most abbreviations of proper names—NATO, FBI (but some style guides and writing handbooks call for using initial capitalization only for extensive and established acronyms, as with Nasdaq); most abbreviations for units of measurement are not capitalized, but check a dictionary or style guide for exceptions
