Domain E · Ethics · Task E.7

A BCBA suspects that a client is being abused at home based on behavioral observations. As a mandated reporter, their obligation is to:

AReport suspicions to the BACB for guidance before contacting authorities
BConduct their own investigation until suspicion is confirmed by a third party
CReport to appropriate child or adult protective services as required by law, regardless of certainty
DDiscuss the concern with the client's family before filing any report

Explanation: As mandated reporters, BCBAs are legally and ethically required to report suspected abuse to appropriate authorities. The legal standard is reasonable suspicion — not certainty. Self-investigating or waiting for third-party confirmation can violate legal requirements and delay protection for the client.

What helped me most was that many of the domains have really long questions. It helped me practice dissecting the question and prepared me for the real test that also had several lengthy questions.
