The most critical ethical and professional consideration when delegating duties to supervisees whether they are RBTs BCaBAs or those pursuing certification is competence Ensuring supervisee competence and training is paramount BACB Ethics Code for Behavior Analysts Standard 205 Delegating Tasks and Supervision Tim as the supervising BCBA holds ultimate responsibility for the services provided If his supervisees are not competent or adequately trained in parent training assessments or data analysis their performance could be ineffective harmful or unethical even if under supervision He must verify that they have the necessary knowledge skills and abilities before assigning such responsibilities and provide additional training and supervision as needed While having duties outlined in a job description is good practice it does not guarantee competence A job description may list tasks but Tim still needs to ensure the individual is prepared for those tasks Obtaining client or guardian consent is generally a good practice for transparency and in some cases may be ethically required if the supervisees role significantly changes the service delivery but it doesnt supersede the fundamental requirement of competence The idea of only delegating tasks typically performed by RBTs is too restrictive and not the primary ethical concern Many supervisees eg those pursuing BCBA certification are capable of and are expected to learn to perform tasks beyond the typical RBT scope provided they are competent and under appropriate supervision The focus should be on the individuals ability not a generic role definition
