Bulleted and numbered lists are permitted by the APA Style rules; however, if you're unsure if your instructor will permit them in your assignment, please check with your instructor. Keep in mind that because bulleted or numbered lists only provide surface-level information rather than include analysis, and because the focus of academic writing is to demonstrate your critical thinking, these lists are used sparingly in formal academic writing in favor of communicating your ideas in complete sentences and paragraphs. See below for information regarding formatting lists.
Bulleted lists
The capitalization and punctuation for each bulleted item depends on whether the items form sentences or sentence parts. If the bulleted text is a full sentence, capitalize the first letter of the first word and end the paragraph with a period. For example:
When a bulleted list separates three or more elements within a sentence, “begin each bulleted item with a lowercase letter” and either punctuate each item in the list as parts of a sentence (e.g., inserting commas), or exclude punctuation after each item (American Psychological Association [APA], 2020, pp. 190-191). For example:
In December 2018, British Columbia had an extreme storm that caused:
This storm affected multiple areas on Vancouver Island, including:

Numbered lists
Numbered lists are helpful to identify the organization of information, such as "itemized conclusions” or “steps in a procedure" (APA, 2020, p. 190). Keep the following steps when creating a number list:
Please keep in mind that "the use of 'numbered lists' may connote an unwanted or unwarranted ordinal position (e.g. chronology, importance, priority) among the items" (APA, 2020, p. 190). To avoid this suggestion of position, use a bulleted list instead. For more information on numbered lists, see Numbered Lists in the APA Style Blog.
Lettered lists within a sentence
Lettered lists within a sentence are a good way to identify elements in a series within a paragraph or sentence without breaking the elements into a numbered or bulleted list. To indicate the list, use lowercase letters in parentheses (American Psychological Association, 2020, p. 189). For example, "students were asked to choose between completing (a) a formal research essay, (b) a documentary-style video, (c) a multi-media experience that involves participants". To punctuate a lettered list within a sentence, use commas between each of three or more items, or use semicolons when separating items that include commas, such as a series of phrases (APA, 2020, p.189). See Lettered Lists from the APA Style Blog for more information and examples.
