What is a key component of conducting mastery checks?

The correct choice emphasizes the importance of administering mastery checks independently to evaluate a student's understanding without external assistance. This approach allows for an authentic assessment of the student's grasp of the material, free from influence or collaboration with peers or teachers. By ensuring that a mastery check is completed independently, educators can more accurately gauge the student's ability and identify specific areas where further instruction may be needed. The focus is on measuring the student's own understanding and skills, making it a pivotal aspect of effective mastery checks.

In contrast, the other options suggest different procedures that could compromise the integrity of the assessment. For instance, conducting checks with supervision might lead to assistance being provided, which could skew results, while revisiting checks multiple times before completion could influence the student's performance and not accurately reflect their true capabilities. Similarly, requiring peer evaluation may not focus solely on the individual's understanding, thereby diluting the reliability of the mastery check as a personal assessment tool.
