Determining the consistency of a knowledge assessment is fundamentally about understanding how stable and reliable the assessment results are over time. Testing the same group at different times directly measures this consistency, also known as test-retest reliability. If the performance of a group is consistent when they take the same assessment on different occasions, it indicates that the assessment effectively measures the knowledge it is intended to measure.

This approach controls for variations in group dynamics, learning experiences, or other external factors since the same individuals are being assessed multiple times. It emphasizes the importance of the assessment tool itself, rather than external factors that could influence results, thus providing a clear metric for reliability.

In contrast, the other options focus on different aspects that do not directly measure the assessment's consistency. Comparing results from different groups can show variations due to different contextual factors rather than the reliability of the assessment. Utilizing feedback from participants may provide insights on the assessment's effectiveness or clarity but does not measure reliability directly. Analyzing peer reviews of the assessment can offer valuable perspectives about its design or appropriateness, but again, it does not provide a direct measure of consistency like repeated testing does.
