What does the Letter-Word Identification subtest measure?

The Letter-Word Identification subtest measures the ability to recognize words at sight, which is essential for reading fluency. This skill involves instant recognition of familiar words without the need for decoding, allowing a reader to process text more efficiently. Mastery of sight word recognition supports overall reading comprehension, as readers can focus on understanding the content rather than on decoding each individual word. The subtest thus highlights an important foundational skill in literacy development, relevant for those involved in structured literacy education and assessing language abilities.

The other options involve skills that are not measured by this specific subtest. Writing letters and words relates to different aspects of literacy that focus on composition, while memorization of words may not indicate real reading comprehension or fluency. Predicting word meanings also does not align with what the Letter-Word Identification subtest specifically measures, which is the immediate recognition of words rather than inferential skills.
