APA Sixth Edition Subtitle Levels

  • Distinguishing between numerous sections and sub-heading levels through differences in text format can help establish hierarchy and guide readers through a lengthy document. APA has very specific guidelines for each subhead level that need to be followed consistently. See the example below.

    APA Subtitle Levels Helpful Tips:

    • Chapter numbers and titles should be formatted according to IUP’s Thesis-Dissertation Manual, and as such, do not count as a level of subhead in APA.
    • Section titles must match exactly, word for word, between the Table of Contents and the body (including punctuation and capitalization).
    • A document should not include a subhead level without having a level above it previously in the document's hierarchy (i.e. do not have a level one and then skip to a level three).
    • Do not have empty subheads (i.e. a level one heading with no body text that leads directly to a level two heading below it).
    • APA provides for five levels of subheads; a document that requires more levels should perhaps be reorganized.
