Which practice helps mitigate bias in assessment?

• A. Rely on intuition
• B. Use a single measure
• C. Use multiple measures
• D. Use only standardized tests

Answer: (C)

Using multiple measures is the approach that reduces bias in assessment. Each method taps different aspects and contexts of a student’s performance, and every measure has its own limits and potential biases. By gathering information from a variety of sources—achievement tests, cognitive assessments, curriculum-based measurements, classroom observations, work samples, and input from teachers or parents—you create a check against the errors or biases that any single measure might carry. This triangulation leads to a more accurate and fair understanding of a student’s strengths, needs, and what supports they may need.

For example, if a student has difficulty with reading, relying on just one test could misrepresent their abilities due to test format, language demands, or momentary factors. Combining multiple data points across settings and times gives a fuller picture and supports better decisions about instruction and accommodations.

Relying on intuition is vulnerable to personal biases, and a single measure provides limited evidence. Even standardized tests, while valuable, can be biased or limited in scope if used alone. Using multiple measures helps balance these issues and yields a fairer, more valid assessment.
