The apa6 document class doesn't use enumerated headings, but I want my headings to look like:

  1. Something

1.1 Something

1.2 Something

  1. Something

2.1 Something


How do I enable this?

  • Welcome to TeX.SE. As it stands, your posting is quite terse. Do you want sectioning headers with just numbers and no titles. Incidentally, apa6 can be both a document class and a LaTeX package. Please confirm which possibility applies.

  • Aah, good point. I'll update my post. I'm using it in my documentclass -- is this not a package? Sep 24, 2015 at 13:32

The class does


so sectional units below \part are not numbered. If you want to number them, you need to increase the counter to the desired level:



\section{Test section}
\subsection{Test subsection}
\subsubsection{Test subsubsection}

enter image description here


Because of how apa6 works, Gonzalo Medina's answer is not quite enough on its own (at least when running in man mode -- I haven't checked the other output formats). You will end up with "1 Abstract", "2 {paper title}", "3 Introduction", and any subsections in appendices will have confusing numbers attached. For numbering just the sections within the main body of the article, and skipping numbering subsections within appendices:

  • Put \setcounter{secnumdepth}{3} immediately after your call to \maketitle
  • Put \setcounter{secnumdepth}{0} immediately before your \bibliography.
