Why is it important to mitigate extraneous factors during assessments?

Mitigating extraneous factors during assessments is crucial for accurately attributing observed changes to the intervention being evaluated. This means ensuring that any improvements or outcomes measured can be directly linked to the specific intervention rather than being influenced by unrelated variables or conditions. By controlling for extraneous factors, school psychologists can confidently determine the effectiveness of their strategies and make informed recommendations based on solid evidence. This is essential in any educational assessment, as it ensures that data is reliable and valid, ultimately supporting better decision-making in schools.

While factors such as funding, legal compliance, and teacher evaluations can have their own importance, they do not directly relate to the issue of accurately measuring the impact of interventions, which is the primary focus of a well-conducted assessment.
