• A. Phonics Assessment
• B. Reading Comprehension test
• C. Vocabulary assessment
• D. Spelling inventory

Answer: (A)

Oral Reading Fluency scores that are below grade level point to possible decoding issues that limit how smoothly a student reads. The next diagnostic step is to assess phonics—looking at letter-sound relationships, blending sounds into words, and decoding unfamiliar words. When you identify specific decoding gaps, you can tailor instruction to improve those foundational skills, which is what often unlocks gains in fluency and later in comprehension. A reading comprehension test would measure understanding but can be affected by weak decoding, so it isn’t the clearest next diagnostic when the goal is to uncover the root cause of low fluency. A vocabulary assessment shows word knowledge, and a spelling inventory checks encoding skills, but neither targets decoding patterns as directly as a phonics assessment does.
