BCBA Charla is providing training to one of her trainees as part of a competency assessment. Charla initially used BST to help increase the overall duration of client engagement. After the training she observed performance informally once or twice a week, it appeared that the trainee was implementing the protocol correctly. The client appeared more engaged during the sessions, and BCBA Charla felt she did a job well done, despite a lack of data. Given this scenario, which ethics standard is being violated? 4.03 Supervisory Volume 4.10 Evaluating Effects of Supervision and Training 4.04 Accountability in Supervision 4.11 Facilitating Continuity of Supervision
