What does the Psuedoword Decoding subtest measure?

The Pseudoword Decoding subtest specifically measures the ability to read nonsense words aloud. This aspect is crucial in assessing a learner's phonemic awareness and their understanding of the sound structure of language without relying on prior knowledge of real words. By focusing on nonsense words, this subtest evaluates the test-taker's ability to apply phonics rules and decoding strategies in a controlled manner, thereby reflecting their decoding skills based on their phonological processing abilities. This skill is essential for developing reading proficiency, as it demonstrates a student's capacity to break down unfamiliar words into recognizable sounds and syllables, which is foundational for reading both real and complex words.

In contrast, the other options do not align with the specific purpose of the Pseudoword Decoding subtest. For example, understanding word meaning and comprehending stories focus more on vocabulary and comprehension skills, while decoding real words pertains to reading known vocabulary rather than assessing phonetic skill on newly encountered, non-meaningful terms.
