What is the primary purpose of curriculum-based measurements (CBMs) in progress monitoring?

• A. To measure rate of growth toward goals.
• B. To determine teacher's annual salary.
• C. To grade school's athletic performance.
• D. To replace standard testing.

Answer: (A)

Curriculum-based measurements in progress monitoring are used to track how quickly a student is gaining skills aligned with what is taught in class. By administering brief, curriculum-aligned probes repeatedly, educators plot performance over time and determine the slope, or rate of improvement, toward established goals. The primary value is to see whether the student is making adequate progress toward the target and to adjust instruction if needed, rather than simply assigning a grade or preparing for standardized tests. This approach provides timely feedback and helps teachers tailor supports so the student can reach the goal within the desired timeframe.
