Final answer:
Proctoring an assessment with nonsense words is designed to evaluate phonemic awareness and decoding skills, not reading comprehension, vocabulary, grammar, or listening skills.
Step-by-step explanation:
The purpose of proctoring an assessment with nonsense words is to test for proficiency in phonemic awareness and decoding skills. This kind of assessment checks a student's ability to apply their knowledge of phonics to read words that are not found in their vocabulary. By using nonsense words, the assessment is ensuring that the student is not relying on memorized vocabulary words, but rather their ability to sound out and blend unfamiliar phonetic elements.
