RBT Supervision for ABA Employers: The Requirements Coordinator, 5% Rule and Records

The BACB gives you two ways to organize RBT supervision, and the choice shows up in your org chart.

In an RBT Supervisor structure, one or more supervisors are responsible for the RBT's services.

In an RBT Requirements Coordinator structure, a coordinator makes sure all of an RBT's supervisors meet the requirements and coordinates supervision across them.

The credentials differ between the two roles.

An RBT Supervisor may hold BCBA or BCaBA certification; the RBT Requirements Coordinator must be BCBA certified.

Since January 1, 2026 there is no third option — the BACB eliminated the noncertified RBT Supervisor role, so both jobs sit with certificants now.

Coordination is real work, not an honorific.

In the coordinator structure, the coordinator is responsible for making sure every RBT they cover meets the supervision requirements each month — that RBT Supervisors are qualified and all requirements are met — and that BACB records stay up to date.

The coordinator may also serve as an RBT Supervisor.

An organization can have more than one coordinator, but each RBT may have only one Requirements Coordinator per organization.

Both roles carry the same training prerequisite: before providing any supervision, RBT Supervisors and RBT Requirements Coordinators must complete the 8-hour supervision training based on the BACB's Supervisor Training Curriculum Outline (2.0) and upload it to their BACB portal account.

Two structural rules catch employers out.

The relationship bar says an RBT may not be related to, superior to, an employer of, or in a multiple relationship with their RBT Supervisor or Requirements Coordinator.

That does not stop your clinic from employing both people — it stops an RBT from being their supervisor's boss, and an RBT who pays for supervision is not treated as the supervisor's employer.

The coverage rule is the other one.

The BACB says an RBT's supervisor or coordinator should be employed by the same organization as the RBT or have a contractual relationship with the RBT's clients, and every client the RBT serves must be covered — its own example is that having a supervisor for three of your clients but not the fourth is not permissible.

One misconception to retire while you assign the roles: the idea that a newly certified BCBA needs a consulting supervisor before they can supervise RBTs.

The BACB's consulting-supervisor requirement applies only to supervising fieldwork trainees, not to supervising RBTs or BCaBAs — a new BCBA can take RBTs on without one, once they have met the same supervisor requirements as any other supervisor, including the 8-hour training above.

The number itself is simple: at least 5% of the hours the RBT spends providing behavior-analytic services each calendar month.

The denominator is the RBT's own service-delivery hours — not your BCBAs' hours — and both the BACB and CMS frame the figure as a floor.

CMS's August 2026 Medicaid ABA Toolkit calls the 5% a minimum credentialing requirement rather than a recommended supervision level, and notes that the clinical practice guidelines it cites point to 10 to 20% supervision relative to direct treatment hours.

The shape of the month matters as much as the total.

Supervision must include at least two face-to-face, real-time contacts — phone calls and email do not count — and the supervisor must observe the RBT providing services in at least one of them.

At least one of the two sessions must be individual, with no other RBTs or trainees present.

The other may be a small-group meeting of 2 to 10 RBTs, and the group may never exceed 10 RBTs regardless of how many supervisors attend.

The observation does not have to be on site.

The BACB allows it by web camera or video-conferencing — in-person observation is preferred — but video monitoring on its own, without real-time interaction or feedback, may not count as supervision.

Supervision must be client focused, and it is a separate BACB requirement from professional development: one event cannot count toward both.

If you share an RBT with another organization, the arithmetic does not pool.

An RBT who splits their time between two employers must meet the full requirement separately at each one — the BACB's example is that 3% supervision at organization A plus 2% at organization B does not satisfy the rule.

This is the employer's view of the rule; the clinician-facing explanation lives in RBT supervision requirements (the RBT's side).

Two systems carry the month: the BACB's portal and your own tracker.

The portal side is binary — for an RBT's certification to be active enough to practice, bill, or represent themselves as an RBT, their RBT Supervisor(s) and/or RBT Requirements Coordinator must have them listed as a supervisee in a BACB portal account, and under a coordinator structure only the coordinator has to list them.

Check that listing before an RBT's first shift, not after.

Your tracker is where the 5% arithmetic lives.

For each RBT each month it should show: service hours logged, supervision hours set against them, the two contacts scheduled with at least one held individually, the observation completed, and any group headcount checked against the 10-RBT ceiling.

Treat supervision capacity as a planning input rather than an afterthought.

The BACB sets no maximum number of supervisees per BCBA; it tells supervisors to weigh their own caseload, how many hours each supervisee works, the time their supervision requires, client needs and program settings.

The defensible internal cap is the one you can justify with those factors in writing — not a number borrowed from another clinic.

Budget for the payer layer on top of the BACB's rules.

CMS notes that states and payers may add their own ABA supervision requirements on caseloads, supervision-to-treatment ratios, or the minimum or maximum number of RBTs a supervisor oversees.

In its August 2026 toolkit, CMS reports that Nebraska Medicaid caps an ABA supervisor's caseload at 24 technicians; that Louisiana Medicaid requires state-certified assistant behavior analysts and registered line technicians to be supervised by a licensed behavior analyst for 2 of every 10 hours of ABA services; and that Arkansas Medicaid requires supervising BCBAs to observe BCaBAs and RBTs in person for at least 5% of their treatment hours and 1 hour every 30 days, to be enrolled Arkansas Medicaid providers, to be on call during sessions, and to approve BCaBA and RBT notes before a claim is submitted — rules Arkansas expects to revise, so confirm the current state manual.

State law can reach your job titles too.

In Texas, the behavior analyst licensing law does not apply to a paraprofessional technician working under the authority and direction of a licensed behavior analyst or licensed assistant behavior analyst — but only if the person is designated as an "applied behavior analysis technician," "behavior technician," "tutor," or "front-line therapist."

If you are building the technician team alongside the supervisor bench, start from our hub for hiring RBTs.

The BACB tells you exactly what the file must contain.

RBT supervision records must show the days and times the RBT provided behavior-analytic services, the dates and duration of supervision, the format of each session (one-on-one or group), the dates direct observations occurred, and the names of the supervisors who provided supervision.

Two more items get missed.

Records must include proof of the supervisor's relationship to the client, and additional documentation — session notes, for example — in the event of discrepant records.

Retention runs long: the RBT and the RBT Supervisor or RBT Requirements Coordinator must keep supervision documentation for at least 7 years, even after the supervisory relationship ends or someone else has assumed responsibility.

Audit mechanics turn that filing system into an operating requirement.

The BACB may audit current and former RBTs, RBT Supervisors and RBT Requirements Coordinators at any time; parties get 14 days to submit requested documents in the typical audit, and documents submitted after the deadline are not reviewed or considered.

Build the tracker so you can produce a complete file for a technician who left two years ago inside that window.

Supervisors and coordinators also carry documentation duties when something goes wrong.

On learning of a possible ethics violation by an RBT, they must investigate and document the alleged violation, then decide whether to handle it internally or file a Notice of Alleged Violation with the BACB.

The bright line: an RBT may practice only while they have an RBT Supervisor or RBT Requirements Coordinator on record with the BACB and reflected on the Certificant Registry.

Without that listing the certification is not active to practice, to bill, or to represent the person as an RBT — so a missed portal update takes a technician off the schedule, not just off the paperwork.

The consequences scale with the violation.

An RBT found substantially noncompliant with the supervision requirements faces immediate termination of certification, or termination of their eligibility to be recertified, and is prohibited from reapplying for six months.

A Notice of Alleged Violation may also be submitted against the RBT Supervisor and/or RBT Requirements Coordinator when their RBTs are not receiving supervision in accordance with the requirements — the exposure reaches your certificants, not just the technician.

Not every gap is a violation.

RBTs who are not currently providing behavior-analytic services do not need monthly supervision to maintain certification, though they must still meet the other maintenance requirements — the duty follows service hours.

The preventable failure point is offboarding.

When an RBT's supervisor or Requirements Coordinator changes, that supervisor or coordinator must make the change in their BACB portal account when the supervisory relationship ends — make it a same-day checklist item on every resignation and termination, and reassign every client before the departing supervisor's last day so no RBT is left uncovered.

The BACB warns supervisors to plan transitions before discontinuing supervision, because abruptly ending supervision of RBTs and BCaBAs can negatively impact services.

January 1, 2026 rebuilt parts of the RBT framework.

The noncertified RBT Supervisor role is gone: RBT Supervisors must hold BCaBA or BCBA certification.

Recertification moved from every year to every 2 years, with 12 hours of professional development units (PDUs) required in each 2-year cycle.

The PDU rules reward employer-run training, within limits.

An organization's in-service training related to behavior-analytic service delivery counts toward PDUs when a BCaBA, BCBA or BCBA-D at the RBT's organization provides it — training on a specific client's program does not count.

Ongoing RBT supervision, client-specific training and supervised fieldwork toward BCaBA or BCBA certification do not count either.

The transition was staggered.

Current RBTs recertified during 2026 with the RBT Recertification Competency Assessment, and their next recertification date sits 2 years out; RBTs who became certified or recertified in 2026 next recertify in 2028 with 12 PDUs and no competency assessment.

If you run your own 40-hour training, its trainers must be active BCBAs or BCaBAs who have completed the 8-hour supervision training — they may use assistants who hold RBT certification or higher — and assistant assessors on the RBT Initial Competency Assessment must hold RBT certification or higher.

The credential math frames the staffing problem.

As of October 1, 2026, the BACB counted 259,577 RBTs, 88,013 BCBAs and 4,931 BCaBAs holding certification, and every RBT delivering services needs qualified supervision each month.

That makes supervision capacity a hiring question as much as a compliance one — our behavioral health hiring hub keeps the role-by-role staffing picture in one place.
