What is the most appropriate action to take when reviewing data on a student's performance with a target skill?

Clarifying characteristics of the target skill is essential when reviewing data on a student's performance because it allows for a more precise understanding of what the skill entails and the expected outcomes. This clarity helps educators identify specific areas where the student may excel or struggle. By clearly defining the characteristics, educators can effectively evaluate the student's progress, make informed decisions about instruction, and tailor interventions to target specific aspects of the skill that require improvement.

In contrast, while having a staff member mentor others, providing a warm-up period for practice, and modeling the target skill with feedback can be beneficial actions in different contexts, they do not directly address the need for a clear understanding of the skill itself. Mentoring can support broader professional development, while warm-up periods and modeling focus on practice and demonstration rather than data analysis and interpretation. Therefore, clarifying the characteristics ensures that the evaluation process is grounded in a solid understanding of the skill, which is vital for effective educational strategies.
