Problem: Waylon is a BCBA who recently completed an assessment and subsequent update to his client's behavior intervention plan (BIP). Prior to conducting the assessment and updating the BIP, Waylon didn't seek informed consent from the client or the client's guardian. In Waylon's opinion, there's no point in seeking informed consent because the guardian already signed an informed consent form the last time he made changes. Waylon also stated that this client's guardian is really hard to get ahold of, so they aren't going to schedule a time to go over the changes.
