Note: APA 7th edition was released in October of 2019 and is still being adopted by many instructors. There are some instructors who are still using APA 6th edition and expect work to be turned in to use it as well. Please make certain to bring this up with your teacher, especially if it is not listed on your class's syllabus which edition will be used.
Voice describes the relationship between a verb and the subject and object associated with it.
Both the active and the passive voice are permitted in APA Style. However, writers often overuse the passive voice.
