Papers in APA format — have the following parts (if the part is needed.) The order is always the same:
"APA Style provides a foundation for effective scholarly communication because it helps writers present their ideas in a clear, precise, and inclusive manner.
Uniformity and consistency enable readers to (a) focus on the ideas being presented rather than formatting and (b) scan works quickly for key points, findings, and sources.
Style guidelines encourage authors to fully disclose essential information and allow readers to dispense with minor distractions, such as inconsistencies or omissions in punctuation, capitalization, reference citations, and presentation of statistics."
