What does accuracy in reading refer to?

Accuracy in reading primarily refers to the ability to read words in a text without making errors. This concept emphasizes the importance of correctly recognizing and pronouncing words, which is fundamental for effective reading. When a reader accurately reads text, it allows for better comprehension and fluency, as they can focus on understanding the content rather than struggling with mispronunciations or skipped words.

The other options represent important aspects of reading but do not define accuracy. For instance, reading with varying expression focuses on prosody, which enhances engagement and understanding but is separate from the notion of accuracy. Reading at a high speed refers to reading fluency but doesn't necessarily ensure that the reading is accurate if words are misread. Understanding vocabulary in context is crucial for comprehension, but again, it does not pertain to the act of reading the words accurately in the first place.
