The first thing on your title page is the Running head. It is flush with the left margin. The words Running head are followed by a colon and an abbreviated title of your paper. It must be under 50 characters. Insert the page number on the same lin flush with the right margin.
Your title goes about halfway down the page (if your paper is set to double-space, hit the enter key about 9 times); center the title. Add your name and school.
At the bottom of you page you may add an Author Note. This item is optional; ask your instructor if it is required.
The examples below illustrates a title page. In this example, the Running head: and page number are in the header (Example 2). I have also turned on the show paragraph marks (see item marked in red; Example 1). This allows me to count the number of lines on my paper so I know exactly where the center is.
