Which option best describes how data should be used when determining ADHD eligibility in a diverse student population?

• A. Data from a single source is sufficient for a decision
• B. Data from multiple sources should be used to determine educational impact
• C. Only standardized test scores are necessary
• D. Parental opinion alone should determine eligibility

Answer: (B)

When deciding ADHD eligibility, the key idea is to base decisions on information gathered from multiple sources over time and across settings so you can see how symptoms affect learning in real school contexts. Data from teachers, parents, and other observers, plus direct observations, work samples, and progress-monitoring data, together create a fuller, more reliable picture than any single measure. This multi-source approach helps demonstrate a pattern of impairment in attention, organization, and task completion that interferes with academic performance, which is what eligibility decisions must show.

In a diverse student population, gathering data from several sources also helps account for cultural or linguistic differences that can influence how behaviors are viewed or reported. It reduces bias and ensures that the observed impact on education reflects the student’s functioning across different environments, not just in one setting or on one test. Relying on just one source—or on standardized tests alone—or on parental opinion alone misses important evidence about how the student actually learns and behaves in school, which is essential for a fair and accurate determination.
