What does the Language Assessment Scales (LAS) measure in K-12 students?

The Language Assessment Scales (LAS) is designed to assess various aspects of language proficiency in K-12 students, particularly focusing on skills that are critical for academic success. The correct choice emphasizes that the LAS evaluates content such as vocabulary, listening, comprehension, and storytelling.

By incorporating these elements, the LAS provides a comprehensive assessment of a student's language abilities. Vocabulary knowledge is essential for reading and communication, while listening skills contribute to understanding spoken language. Comprehension is crucial for processing and interpreting information in both oral and written forms, and storytelling reflects a student's ability to synthesize information and convey it effectively. This multifaceted approach helps educators identify students' strengths and areas for improvement, allowing for tailored instruction that meets individual needs.

Options that focus solely on reading comprehension or oral proficiency do not capture the full breadth of what the LAS measures. Similarly, assessing mathematical skills is outside the scope of the LAS, as it is specifically aimed at evaluating language skills rather than quantitative reasoning.
