QARs, CDQARs, and CDIs must be designated in writing by the person in authority who is responsible for determining the duties of their office.
Step-by-step explanation:
QARs, CDQARs, and CDIs must be designated in writing by the person in authority who is responsible for determining the duties of their office. This can vary depending on the organization or institution. For example, in a school setting, QARs (Question-Answer Relationships), CDQARs (Comprehension-Directed Question-Answer Relationships), and CDIs (Corrective Doubt Indicators) might be designated by the principal or head of the department. In a workplace, these designations may be made by a supervisor or manager in charge of the relevant department.
