What is the purpose of check for understanding in differentiated instruction?

• A. Identify gaps in understanding to adjust instruction
• B. Determine final exam grade
• C. Assess long-term mastery
• D. Rank students

Answer: (A)

Check for understanding in differentiated instruction centers on identifying gaps in what students understand or can do right now, so you can adjust teaching to meet them where they are. These checks are formative—quick, frequent checks that reveal misconceptions, procedural errors, or incomplete reasoning. With that information you can decide to re-teach, provide a different representation, offer additional practice, or adjust grouping and supports, tailoring instruction to readiness, interest, and learning preferences. They aren't about assigning a final grade or ranking students, and they don't measure long-term mastery by themselves; they're diagnostic tools to guide the next steps in instruction. For example, an quick exit ticket showing several students misapprehend a concept signals you should revisit with a different explanation or model before moving on.
