What does the Writing Samples subtest evaluate in the WIAT-II?

The Writing Samples subtest in the WIAT-II specifically assesses a student's writing abilities, which includes their capability to compose written language effectively. This involves not only the speed of writing letters and words but also the quality of their written expression, including organization, coherence, and the appropriate use of vocabulary.

While the other options focus on different skills—oral presentations, listening comprehension, and mathematical problem-solving—the Writing Samples subtest is uniquely designed to evaluate how well a student can translate their thoughts into written form, which encompasses aspects like handwriting speed and penmanship. Therefore, option B accurately reflects the focus of this subtest.
