1 1/15 After a brief interruption, the RBT verifies whether to continue the procedure or document a condition affecting the data. During in a home session with new materials, Mateo receives instruction on how to document variables affecting progress. The BCBA notices that performance appears to improve, but ambiguous signals are also present: an instruction was repeated, one material changed position, and part of the data depends on applying the written criterion exactly. The RBT must decide without turning a partial observation into a clinical conclusion. Which decision could most compromise procedural fidelity? Which information should guide the RBT response? Describe only the observed pattern, keep the written procedure, and wait for clinical review before changing criteria. Apply the written criterion, record verifiable data, and communicate the relevant variable through the route indicated in the plan. Changing the criterion for convenience compromises fidelity because it alters how performance is interpreted. according to plan Reconstruct missing details at the end using memory, general notes, and comments from adults present.
