Which data or assessment approach is most appropriate for measuring progress over time in response to an academic intervention?

• A. Curriculum-based measurement (CBM)
• B. Diagnostic IQ testing
• C. One-time standardized assessment
• D. Behavioral observation only

Answer: (A)

Measuring progress over time in response to an academic intervention relies on data that are collected repeatedly and reflect the actual curriculum students are learning. Curriculum-based measurement provides exactly that: brief, standardized probes that align with classroom content, administered regularly and often graphing the results to show a student's growth trajectory. Because the probes target instructional material, they are sensitive to small improvements and allow teachers to quickly determine if the intervention is working or if adjustments are needed. This makes CBM a practical tool for ongoing progress monitoring and data-driven instructional decisions. In contrast, diagnostic IQ testing offers a broad snapshot of cognitive abilities at a single point in time and isn’t designed for regular progress tracking. A one-time standardized assessment likewise provides only a single datapoint and tends to miss gradual changes across time. Behavioral observation can inform about engagement or behavior, but it doesn’t measure academic skill progress with the same reliability or efficiency as CBM, though it can supplement overall RTI decisions.
