APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association, (6th ed., 2nd printing).

General APA Guidelines
Your essay should be typed and double-spaced on standard-sized paper (8.5" x 11"), with 1" margins on all sides. You should use a clear font that is highly readable. APA recommends using 12 pt. Times New Roman font.
Include a page header (also known as the "running head") at the top of every page. To create a page header/running head, insert page numbers flush right. Then type "TITLE OF YOUR PAPER" in the header flush left using all capital letters. The running head is a shortened version of your paper's title and cannot exceed 50 characters including spacing and punctuation.
Major Paper Sections
Your essay should include four major sections: the Title Page, Abstract, Main Body, and References.
The title page should contain the title of the paper, the author's name, and the institutional affiliation. Include the page header (described above) flush left with the page number flush right at the top of the page. Please note that on the title page, your page header/running head should look like this:
Running head: TITLE OF YOUR PAPER
Pages after the title page should have a running head that looks like this:
TITLE OF YOUR PAPER
After consulting with publication specialists at the APA, OWL staff learned that the APA 6th edition, first printing sample papers have incorrect examples of running heads on pages after the title page. This link will take you to the APA site where you can find a complete list of all the errors in the APA's 6th edition style guide.
Type your title in upper and lowercase letters centered in the upper half of the page. APA recommends that your title be no more than 12 words in length and that it should not contain abbreviations or words that serve no purpose. Your title may take up one or two lines. All text on the title page, and throughout your paper, should be double-spaced.
Beneath the title, type the author's name: first name, middle initial(s), and last name. Do not use titles (Dr.) or degrees (PhD).
Beneath the author's name, type the institutional affiliation, which should indicate the location where the author(s) conducted the research.

Begin a new page. Your abstract page should already include the page header (described above). On the first line of the abstract page, center the word “Abstract” (no bold, formatting, italics, underlining, or quotation marks).
Beginning with the next line, write a concise summary of the key points of your research. (Do not indent.) Your abstract should contain at least your research topic, research questions, participants, methods, results, data analysis, and conclusions. You may also include possible implications of your research and future work you see connected with your findings. Your abstract should be a single paragraph, double-spaced. Your abstract should be between 150 and 250 words.
You may also want to list keywords from your paper in your abstract. To do this, indent as you would if you were starting a new paragraph, type Keywords: (italicized), and then list your keywords. Listing your keywords will help researchers find your work in databases.

APA Paper Formatting & Style Guidelines
Your teacher may want you to format your paper using APA guidelines. If you were told to create your citations in APA format, your paper should be formatted using the APA guidelines as well.
- Use white 8 ½ x 11” paper.
- Make 1 inch margins on the top, bottom, and sides
- The first word in every paragraph should be indented one half inch.
- APA recommends using Times New Roman font, size 12.
- Double space the entire research paper
- Include a page header known as the “running head” at the top of every page. (To make this process easier, set your word processor to automatically add these components onto each page)
- To create the running head/page header, insert page numbers justified to the right-hand side of the paper (do not put p. or pg. in front of page numbers)
- Then type “TITLE OF YOUR PAPER” justified to the left using all capital letters
- If your title is long, this running head title should be a shortened version of the title of your entire paper

APA Paper Components
Your essay should include these four major sections:
- Title Page
- Main Body
This page should contain four pieces: the title of the paper, running head, the author’s name, institutional affiliation, and an author’s note. Create the page header/running head as described above.
*Please note that only on the title page, your page header/running head should include the words “Running Head” before your title in all capitals. The rest of the pages should not include this in the page header. It should look like this on the title page:
- The title of the paper should capture the main idea of the essay but should not contain abbreviations or words that serve no purpose
- It should be centered on the page and typed in 12-point Times New Roman font. Do not underline, bold, or italicize the title.
- Your title may take up one or two lines, but should not be more than 12 words in length.
- All text on the title page should be double-spaced in the same way as the rest of your essay
- Do not include any titles on the author’s name such as Dr. or Ms.
- The institutional affiliation is the location where the author conducted the research
Sample Title page:
On the following page, begin with the Running title.
- On the first line of the page, center the word “Abstract” (but do not include quotation marks).
- On the following line, write a summary of the key points of your research. Your abstract summary is a way to introduce readers to your research topic, the questions that will be answered, the process you took, and any findings or conclusions you drew.
- This summary should not be indented, but should be double-spaced and less than 250 words.
- If applicable, help researchers find your work in databases by listing keywords from your paper after your summary. To do this, indent and type Keywords: in italics. Then list your keywords that stand out in your research.
Sample Abstract page:
On the following page, begin with the Body of the paper.
- Start with the Running title
- On the next line write the title (do not bold, underline, or italicize the title)
- Begin with the introduction. Indent.
- The introduction presents the problem and premise upon which the research was based. It goes into more detail about this problem than the abstract.
- Begin a new section with the Method. Bold and center this subtitle The Method section shows how the study was run and conducted. Be sure to describe the methods through which data was collected.
- Begin a new section with the Results. Bold and center this subtitle. The Results section summarizes the data. Use graphs and graphs to display this data.
- Begin a new section with the Discussion. Bold and center this subtitle. This Discussion section is a chance to analyze and interpret your results.
- Draw conclusions and support how your data led to these conclusions.
- Discuss whether or not your hypothesis was confirmed or not supported by your results.
- Determine the limitations of the study and next steps to improve research for future studies.
** Throughout the body, in-text citations are used and include the author’s/authors’ name(s) and the publication year. In APA format page numbers are not used in in-text citations.
Ex: (Wilkonson, 2009).
For more information about how to cite properly please see EasyBib’s guides for APA citations based on the sources you are using.
Sample Body page:
On a new page, write your references.
- Begin with a running title
- Center and bold the title “References” (do not include quotation marks, underline, or italicize this title)
- Alphabetize and Double-space all entries
- Every article/source mentioned in the paper and used in your study should be referenced and have an entry.
