How should section and subsection headings be formatted in APA style?

A research paper written in APA style should be organized into sections and subsections using the five levels of APA headings. APA recommends using subheadings only when the paper has at least two subsections within a larger section. Notice how sections contain at least two smaller subsections in the example below:

Method

Design

Participants

Demographic.

Characteristics.

Limitations

Starting with the first level of heading, the subsections of the paper should progressively use the next level(s) of heading without skipping any levels. Major sections of the paper’s main body, including the Method, Results, and Discussion sections, should always be formatted with the first level of heading. However, keep in mind that the Introduction section, which is preceded by the full title of the paper, should be presented in plain type. Any subsections that fall under the major sections are formatted with the next level of heading.

Note that all paragraphs of the main body, including those that fall under subsections of a larger section, still maintain the pattern of indentation, use Times New Roman font, 12 pt., and are double-spaced. There are no extra lines or spaces between paragraphs and headings.

How are the five levels of APA-style headings formatted?

Format each of the five levels of APA-style headings as demonstrated in the example below. Note that while the example features headings titled “First Level,” “Second Level,” and so on, each heading in your paper should be named according to the section it describes. 

First Level

The first level of heading is bolded and centered, and the first letter of each word in the heading is capitalized. The paragraph text should be typed on the following line and indented five spaces from the left.

Second Level

The second level of heading is bolded and situated flush left, and the first letter of each word in the heading is capitalized. The paragraph text should be typed on the following line and indented five spaces from the left.

Third level

The third level of heading is bolded, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Fourth level

The fourth level of heading is bolded, italicized, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Fifth level

The fifth level of heading is italicized, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.
