Why should criteria be set before conducting reliable self-assessment?

Correct answer: To keep the evaluation consistent and evidence-based

Pre-set criteria provide a clear standard against which performance can be judged. They make self-assessment more consistent, fair, and evidence-based because the learner uses the same expectations when reviewing achievements and improvement areas. Option B is correct. Choosing criteria merely to obtain a preferred result creates bias, focusing only on strengths is incomplete, and clear criteria do not eliminate the usefulness of feedback from others. Reliable assessment combines standards, evidence, and reflection.
