What type of evidence best supports disability determination?

• A. Multiple measures across domains and contexts
• B. A single test score
• C. A teacher impression
• D. Attendance record

Answer: (A)

Disability determinations are best supported by gathering multiple measures across different domains and settings. This approach gives a complete and reliable view of how a student’s strengths and challenges affect learning, showing patterns that single data points might miss. A lone test score can be affected by momentary factors like motivation or test anxiety and may not reflect typical performance. A teacher’s impression, while useful, is subjective and incomplete without systematic evidence. An attendance record shows exposure to instruction but does not reveal actual abilities or barriers to learning. By integrating formal assessments, classroom observations, and information from multiple contexts and professionals, you build a robust picture of the student’s functioning necessary for an accurate disability determination.
