APA 6th Edition

The Publication Manual of the American Psychological Association (American Psychological Association, 2010) is an American publication, so the manual requests that authors use American spelling (p. 96). However, if you're a student at Royal Roads University, you're studying at a Canadian university, so Canadian spelling is usually preferred. You could check with your instructor to see if s/he has a preference, but if not, please be consistent. That is, if you're using Canadian or American spelling, use the same approach throughout the document and don't flip between them.

APA 7th Edition

The Publication Manual of the American Psychological Association (American Psychological Association, 2020) is an American publication, so the manual requests that authors use spellings that conform to the Merriam-Webster.com Dictionary, which provides American spellings (p. 96). If you're submitting a manuscript to an American publication, use American spellings. However, if you're a student at Royal Roads University, you're studying at a Canadian university, so Canadian English spellings are usually preferred. Canadian English has a blend of American and British spellings; see the section called "Spelling Tendencies" in Canadian English for information. To look up the Canadian spellings of words, try the Canadian Oxford Dictionary (requires RRU username and password).

If you are unsure of which spellings to use, please check with your instructor or supervisor. Whether you use American or Canadian English spellings, please be consistent throughout the document.
