When should an intervention be changed according to data analysis?

An intervention should be considered for change when 2-3 data points fall below the aim line as this indicates a pattern that may suggest the current intervention is not effective. Monitoring data points in relation to an aim line helps assess whether a student is making adequate progress towards specific goals. When multiple data points consistently fall below the aim line, it signals that the strategy may not be producing the desired outcome, warranting a re-evaluation of the intervention being used.

This approach is rooted in data-driven decision-making, which is critical in school psychology and intervention planning. Addressing student needs effectively often requires adjustments based on observable progress or lack thereof, and a threshold of 2-3 data points provides a clearer indication of a trend rather than basing decisions on isolated data points, which may not accurately represent overall performance.
