What aspect of reading does the ACT test measure?

The ACT Reading test measures your ability to understand, analyze, and interpret written material. It doesn't test your prior knowledge of the topics covered in the passages, but rather your ability to comprehend the information presented and answer questions based on the text itself. This involves skills such as:

* Finding main ideas: Identifying the central theme or purpose of a passage.

* Understanding supporting details: Grasping specific facts and information within the text.

* Making inferences: Drawing conclusions based on evidence in the passage.

* Determining the author's purpose and tone: Understanding the author's attitude and intentions.

* Analyzing vocabulary in context: Understanding the meaning of words as they are used in the passage.

* Following the structure and organization of the passage: Understanding how the information is presented.

In short, the ACT Reading test assesses your critical reading skills and how effectively you can extract meaning from different types of texts.
