A QBA supervises 11 behavior technicians across three homes under a contract providing 6 supervision hours per month total, with 2 hours currently allocated to "Renee." Renee runs a DRA with a 5-second prompt delay and differential reinforcement of a mand for "break." Across four fidelity checks: correct SD delivery 100%; prompt delay adherence 40% (she prompts at 1-2 seconds); reinforcer delivered following problem behavior on 3 of 5 opportunities; and she sometimes omits the mand prompt entirely when the client is "already upset." Renee says she "knows the protocol" and has watched the training video twice. The family reports aggression is unchanged and asks that Renee not be replaced.

During a session, a parent says her sister, who is "a therapist" in a neighboring state, wants to observe sessions by video call to "learn the techniques." The parent also asks to pay out of pocket for four additional hours per week because insurance cut her to 10, and asks the analyst to bill the extra hours as supervision so insurance covers it. Separately, the agency's clinical director instructs the analyst to sign session notes for two sessions a technician ran alone while the analyst was on vacation, saying "you're the supervisor, it's the same thing." The analyst is a QBA and depends on this agency for most of her referrals.
