How can teachers assess the effectiveness of a literacy block?

• A. By tracking the number of books read.
• B. By collecting parent feedback.
• C. By evaluating handwriting quality.
• D. By analyzing student growth data across fluency, decoding, vocabulary, and comprehension measures, and adjusting instruction accordingly.

Answer: (D)

The main idea is to use student growth data across key reading skills to judge how well a literacy block is working and to drive instruction. By regularly measuring progress in fluency (reading speed and accuracy), decoding (sound–letter relationships and word blending), vocabulary (word knowledge), and comprehension (understanding and analyzing texts), you get concrete evidence of how students are developing as readers. Analyzing this data over time helps you see who is making expected gains, who needs targeted supports, and which parts of your instruction are effective. With that information, you can adjust the teaching plan—varying grouping, pacing, small- and whole-group mini-lessons, texts, and practice—to improve outcomes. Other options may touch on exposure or perception, but they don’t provide the direct, actionable insight into students’ reading growth and how to refine instruction.
