Final answer:
RBTs should update aggregate data regularly, typically on a weekly basis, to assess client progress and inform adjustments to the therapy plan.
Step-by-step explanation:
Registered Behavior Technicians (RBTs) are primarily responsible for implementing Applied Behavioral Analysis (ABA) therapy under the supervision of a Board Certified Behavior Analyst (BCBA). As part of their job, RBTs collect data on the progress of their clients. Aggregate data should be updated regularly to ensure that therapy is progressing as intended and to inform any necessary adjustments to the intervention plan.
Typically, this data is reviewed and updated on a weekly basis, although the specific frequency may vary depending on the requirements of the therapy program or the preferences of the supervising BCBA. Therefore, while there is no universal rule for how often to update aggregate data, doing so weekly is a common and effective practice for ongoing assessment of a client's progress.
