Unlike main headings, subheadings are not printed in all capital letters. Some, however, require additional levels. Many students use no more than one or two levels of subheadings. Subheadings must be used in the same order, levels cannot be skipped (for example, a first-level subheading may not be followed immediately by a third-level subheading), and must be used consistently throughout the manuscript. Subheadings are used for divisions of the various chapters or titled sections of the manuscript. Main headings over 4 1/2 inches in length are split and placed on two or more lines with the first line the longest and subsequent lines successively shorter (inverted pyramid form). Main headings of two or more lines are always double spaced. Main headings are always followed by a heading space.

If a subheading follows the main heading, the text begins after a double space. The text begins after a heading space if no subheadings are used. After a heading space, the title of the chapter follows. If the main heading is preceded by the word вЂњCHAPTERвЂќ and its numerical designation, the word вЂњCHAPTERвЂќ and the Roman or Arabic numeral following it begin 2 inches from the top of the page. Main headings always begin a new page of text and are placed 2 inches down from the top of the page. Main headings always begin on a new page, are centered, printed in all capital letters, and used for chapters or titled sections (CHAPTER 1, INTRODUCTION), the titles of the preliminary divisions of the paper (ABSTRACT, TABLE OF CONTENTS, LISTS, ACKNOWLEDGMENTS), and other titled sections of the paper (APPENDIX, REFERENCES). There are two types of headings in any manuscript: main headings and subheadings. Headings establish the organization of the manuscript.
