What is the purpose of collecting baseline data?

Collecting baseline data is crucial in understanding the existing level of a target behavior before any interventions are applied. This provides a reference point to evaluate the effectiveness of the interventions later on. By establishing a baseline, educators and specialists can identify specific areas of need, track progress, and make informed decisions about adjustments to the intervention strategy when necessary. It serves as an essential tool for monitoring growth and development.

In contrast, the other options do not align with the fundamental purpose of baseline data collection. Disregarding future interventions would counter the goal of improving a student's performance. Measuring performance against peers is not the primary aim of baseline data, as it focuses on the individual’s behavior rather than a comparative analysis. Lastly, focusing solely on standardized testing does not encompass the broader spectrum of behavior and performance measurement that baseline data can provide.
