ACT Reading Purpose and Audience: Understand Why Authors Write and For Whom

Author purpose: Why the author writes (to inform, persuade, entertain, critique, explain). Audience: Who reads it (experts, general public, children, specialists). Purpose and audience determine content, tone, vocabulary, and level of detail. A scientific paper (purpose: inform experts; audience: scientists) uses technical language. A children's story (purpose: entertain; audience: kids) uses simple language and playful tone. Questions ask why an author includes certain information or why they use a particular tone. Process: (1) Identify the purpose (why write this?). (2) Identify the audience (who is reading?). (3) Note how purpose and audience shape choices (vocabulary, detail, tone). (4) Explain why the author makes specific content decisions.

Example: A politician writing to voters uses persuasive language and appeals to values. A scientist writing for peer review uses evidence and avoids emotional language. Same topic, different purposes and audiences yield different texts.

Mistake 1: Assuming all informative writing has the same tone. A textbook is matter-of-fact; a popular science article is more conversational. Purpose (inform) is shared, but audience (students vs. general public) differs. Mistake 2: Confusing tone with purpose. An entertaining story might serve to persuade (persuasive purpose). Tone (funny, serious, ironic) is separate from purpose (why write). Mistake 3: Missing that audience shapes detail level. Expert audiences expect technical depth; general audiences need clear explanation. Always ask: What is the author trying to do? Who is reading? How do these shape the text?

During practice, identify purpose and audience, then explain how these drive content and tone choices.

Find a practice passage with clear purpose and audience. For each passage, (1) identify the author's purpose, (2) identify the intended audience, (3) note specific content/tone choices that serve the purpose and audience, (4) predict how the passage would differ if written for a different audience or purpose, (5) predict answers before looking at choices. Do this for two passages this week. This drill trains you to recognize that authors deliberately shape writing for their purpose and audience. Most predictions will match correct answers because purpose and audience directly explain content choices.

Repeat on another passage. By the second passage, you'll automatically factor purpose and audience into interpretation.

Purpose and audience questions appear on most ACT Reading sections. Students who recognize purpose and audience pick up 1 point on the reading section because these factors directly explain why authors make the choices they do.

Use the five-step framework on your next practice test. For every passage, identify purpose and audience before interpreting content. By test day, you should explain author choices through the lens of purpose and audience.
