Central Ideas and Details

Central Ideas and Details questions ask you to identify the main point of a short passage or to locate a specific detail it states. They reward careful reading of what the text actually says rather than what you assume it means. Because each digital-SAT passage is only a paragraph or two, the answer is always grounded in the words on the screen.

Central Ideas and Details is a digital SAT Reading and Writing skill that asks you to identify a short passage's main point or a specific stated detail, choosing the answer grounded in the text rather than assumption.

Stating the central idea or overall claim of a short passage in your own words
Distinguishing the main point from a supporting example or minor detail
Locating an explicitly stated fact and matching it to a paraphrased answer choice
Recognizing when a choice is true of one sentence but not the passage as a whole

Common mistakes

Choosing an answer that is true but too narrow — a real detail that isn't the main idea
Picking a choice that overstates the passage with absolute words like 'always' or 'never'
Bringing in outside knowledge instead of sticking to what the text states
Falling for a choice that reuses key words from the passage but distorts the relationship between them

How to improve
