Why Rapport Matters at Every Level of an ABA Team, Not Just Between BT and Client (Part 1 of 3)

Part 1 of 3 in our series on rapport across the ABA team.

When people think about rapport in ABA therapy, they usually think about the relationship between the RBT or BT and the client, and that relationship absolutely matters. But it is only one piece of a bigger picture. A well-rounded therapy approach depends on rapport across the entire team: the BCBA with the parents, and the BCBA with the BT. When either of those relationships is weak or assumed rather than earned, therapy suffers, even if the client-BT relationship is strong.

Trust With Parents Has to Be Earned, Not Assumed

It is natural for parents to initially look up to a BCBA as the clinical authority in the room, and many will extend trust automatically because of the title and credential. But that assumed trust is fragile, not the same thing as a genuine working relationship. A BCBA has to actively build communication and rapport with parents, the same way a BT builds it with a client, rather than relying on the credential to do that work for them. This is what makes parents actually follow through on strategies at home, not just nod along in a meeting. Trust that is earned through consistent, honest communication holds up under stress in a way that assumed trust never does.

Never Threaten Parents or Staff

A BCBA should never threaten a parent with a call to child protective services, and never threaten a BT with termination. Neither of those decisions is actually the BCBA's to make unilaterally, and using them as a threat damages trust immediately and often permanently. If a genuinely dangerous behavior is happening, elopement is a clear example, since a child running out of the house or into the street can escalate into police involvement or real physical danger, the right response is an honest, direct conversation with the parents about the actual risk, followed by real problem-solving. That might mean discussing appropriate locks or safety measures in the home, working through the specific triggers for the behavior together, or connecting the family with additional agency support. A threat closes down communication. A collaborative safety conversation, built on the trust already established, is what actually reduces dangerous behaviors in the home over time, not out of fear, but because the family trusts the plan and the person presenting it.

A BT Deserves Guidance, Not Dismissiveness

Many BTs come into this field without deep prior ABA experience, and it takes real time to learn not just the terminology, but how to actually translate a written goal into a natural, engaging activity in the moment. Even with tools like a prepared schedule and timer, that translation skill develops with support and practice, not instantly. When a BCBA treats a BT with impatience or a lack of respect during that learning process, it does not just harm the BT's confidence, it can genuinely set back the client's progress, since a discouraged or undermined BT is less effective in session. Building a BT's skill is part of the BCBA's job, not a distraction from it.

Joining an Established Session: Build On It, Do Not Tear It Down

Sometimes a BCBA steps into a session that a BT has already been running successfully, the BT built the rapport, set up the schedule, implemented the programs, and the client's focus and participation are already trending in the right direction. This can happen when a new BCBA takes over a case, or when a BCBA who has been less involved decides to join a session directly. The instinct to walk in and restart everything according to personal preference is the wrong one. A BCBA joining a session like this should build rapport first, the same way anyone new to a room should, observe what is already working, ask questions, and offer suggestions collaboratively rather than unilaterally, as long as everything happening is safe. From there, a BCBA can absolutely add new goals or refine the existing setup, working within what the BT has already built rather than discarding it. Coming in with a bull in a china shop mentality does not improve therapy. It disrupts a system that was already working, undermines the BT who built it, and confuses the client who was already making progress within it.

In Part 2 of this series, we look at how BCBAs build that same trust with parents. See Beyond the Data: How BCBAs Build Genuine Rapport with Parents.
