Prepare the headings you wish to appear in your table of contents. Word compiles the table of contents based on the independent styles used for specific headings. To do so, select the heading in your paper you wish to start your table with. Heading can be chapter numbers, part numbers or other options. Click the "Home" tab at the top left of your screen and choose your desired style from the "Styles" options provided. Repeat for each heading or use the format painter to copy the style to each desired heading.
Designate any subsequent levels to be included in the table of contents under each heading. For example, certain chapters may contain subchapters, which are indicated under a different level in the table of contents. To do so, select the appropriate text, navigate to your "References" tab, and select "Add Text" in the "Table of Contents" group. Select the appropriate level for the text. For the previously mentioned example, you’d select level 2. Repeat the steps for each text you wish to appear in the table or use the format painter to copy the changes for each appropriate selection of text.
Create the table of contents under the "References" tab by selecting the "Table of Contents" option. From the drop-down menu, select the desired style of table or select "Insert Table of Contents" to further personalize your options.
Proof the table of contents to make sure it complies with basic APA style standards. For example, the text should be in 10- or 12-point size, the margins should be 1 inch, and all lines should be double-spaced.
