Finding the Main Idea and Supporting Details

Almost every TEAS Reading passage tests one skill above all others: can you find what the passage is really saying?

The main idea

The main idea is the central point a passage makes — what the whole text is about. It is broader than any single fact and ties the passage together.

Topic versus main idea

The topic is the subject in a word or phrase — "hand hygiene." The main idea is the full point the author makes about that topic — "Hand hygiene is the single most effective way to prevent the spread of infection."

Supporting details

Supporting details are the facts, examples, and reasons that back up the main idea. On the TEAS, watch for true details offered as answer choices — a detail can be accurate and still not be the main idea.

Stated versus implied

A stated main idea appears directly, often in a topic sentence at the start or end of a paragraph. An implied main idea is not written out — you infer it from the details as a whole.

Key takeaways

• The main idea is the author's overall point, not just the subject.
• Supporting details prove the main idea — they are not it.
• When no sentence states the main idea, infer it from the details.
