RBT supervision 6

RBT ongoing supervision

Every month · resets monthly

The supervision an RBT needs in every month they provide services.

MoreLess about RBT ongoing supervision

Each calendar month, at least 5% of the hours an RBT spends providing behavior-analytic services must be supervised, across at least two face-to-face, real-time contacts (at least one of them individual), with at least one direct observation of the RBT working with a client. It resets every month, with no running total and no end point, and it is met separately at each organization.

For exampleA month with zero service hours needs no supervision that month.

Where it comes from RBT Handbook (06/2026), ongoing supervision requirements. The 2026 transition left them unchanged.

RBT supervision percentage

At least 5% of monthly service hours

At least 5% of an RBT's service hours each month must be supervised.

MoreLess about RBT supervision percentage

It is worked out on behavior-analytic service hours, not payroll or scheduled time, and measured one calendar month at a time. It is a flat 5%, with no lower rate later on. There is no total to finish: each month starts fresh, and extra supervision doesn't carry over.

For example100 service hours in a month means at least 5 hours supervised.

In the app The RBT dashboard shows each workplace's supervision percentage for the month as you log.

Where it comes from RBT Handbook (06/2026)

Behavior-analytic service hours

What the 5% is measured on

The hours an RBT spends providing behavior-analytic services: the base for the monthly 5%.

MoreLess about Behavior-analytic service hours

The 5% is measured on the hours an RBT spends providing behavior-analytic services that month, not on total or payroll hours. A month with no service hours owes no supervision.

Where it comes from RBT Handbook (06/2026)

RBT supervision contact

Two or more a month · one individual

A face-to-face, real-time supervision meeting. RBTs need at least two each month.

MoreLess about RBT supervision contact

Contacts happen face-to-face and in real time, in person or by live video. Phone calls and email don't count. At least one of the two must be individual, with no other RBTs or trainees there. The other may be a small group of 2 to 10 RBTs, never more than 10, however many supervisors are present.

Where it comes from RBT Handbook (06/2026)

RBT observation

At least one a month

A supervisor watching the RBT work with a client, live.

MoreLess about RBT observation

In at least one contact each month, the supervisor directly observes the RBT providing services to a client. Live video counts. Video monitoring on its own, without real-time interaction or feedback, may not count as supervision.

Where it comes from RBT Handbook (06/2026)

RBT monthly supervision record

ABA FT's record · kept seven years

The record of an RBT's month of supervision that you and your supervisor sign in ABA Fieldwork Tracker. It is our record, not a BACB form.

MoreLess about RBT monthly supervision record

The BACB doesn't publish an official monthly RBT supervision form, but it does say what an RBT's records must show: the days and times services were provided, the dates and length of supervision, individual or group, the dates of direct observations, the supervisors' names, proof of each supervisor's relationship to the client, and additional documentation, such as session notes, if records disagree. The RBT and the supervisor each keep records for at least seven years. They are kept for an audit, not routinely sent to the BACB.

Where it comes from ABA FT's own record (not a BACB form). What a record must contain: RBT Handbook (06/2026), documentation.

Fieldwork hours 7

Unrestricted hours

At least 60% BCBA · 40% BCaBA

Fieldwork beyond delivering therapy, such as assessment and program design. A minimum share is required.

MoreLess about Unrestricted hours

Conducting assessments, designing behavior plans, and analyzing data, for example. BCBA trainees need at least 60% of their total fieldwork hours unrestricted, and BCaBA trainees at least 40%, counted across all of fieldwork, not month by month. Every hour that counts is either unrestricted or restricted, supervision meetings and group supervision included: the activity decides, never the format.

For exampleDesigning a behavior plan is unrestricted; running it with a client is restricted.

Where it comes from BCBA Handbook (updated 06/2026), types of fieldwork activity (p. 17); BCaBA Handbook (updated 06/2026)

Restricted hours

Up to 40% BCBA · 60% BCaBA

Delivering therapy directly, capped as a share of your total hours.

MoreLess about Restricted hours

Implementing behavior plans and running teaching sessions with clients, for example. Restricted hours can be no more than 40% of total fieldwork hours for BCBA trainees and 60% for BCaBA trainees, counted across all of fieldwork. Some activities depend on context: collecting data during treatment is restricted; collecting data for a functional assessment is unrestricted.

Where it comes from BCBA Handbook (updated 06/2026), types of fieldwork activity (p. 17); BCaBA Handbook (updated 06/2026)

Independent hours

Supervisor not present

Fieldwork hours you do without your supervisor there.

MoreLess about Independent hours

Independent hours count toward your total, and each one is restricted or unrestricted. The month's supervision percentage is worked out on all of the month's hours, independent and supervised together.

Where it comes from BCBA Handbook (updated 06/2026)

Supervised fieldwork

2,000 BCBA · 1,300 BCaBA

One of the two fieldwork types: more total hours, with at least 5% of each month supervised.

MoreLess about Supervised fieldwork

2,000 total hours for the BCBA or 1,300 for the BCaBA, under both the pre-2027 and the 2027 standards, with at least 5% of each month's hours supervised. A supervised fieldwork month that falls short of 5% can count fewer of its hours, so the 5% is met.

Where it comes from BCBA Handbook (updated 06/2026); BCaBA Handbook (updated 06/2026); 2027 BCBA Requirements (updated 02/2026) and 2027 BCaBA Requirements (03/2025)

Concentrated supervised fieldwork

1,500 BCBA · 800 BCaBA (1,000 pre-2027)

The other fieldwork type: fewer total hours, with more of each month supervised.

MoreLess about Concentrated supervised fieldwork

1,500 total hours for the BCBA. For the BCaBA, 1,000 under the pre-2027 standards and 800 under the 2027 standards. At least 10% of each month must be supervised, except BCBA under the 2027 standards at 7.5% (BCaBA stays at 10%). A concentrated month that falls short can't be prorated, so that month's hours don't count. Often shortened to concentrated fieldwork.

Where it comes from BCBA Handbook (updated 06/2026); BCaBA Handbook (updated 06/2026); 2027 BCBA Requirements (updated 02/2026) and 2027 BCaBA Requirements (03/2025)

Total fieldwork hours

800 to 2,000

The number of fieldwork hours your pathway needs in all.

MoreLess about Total fieldwork hours

It depends on your credential, your fieldwork type, and (for BCaBA concentrated) your standards: 2,000 (BCBA supervised), 1,500 (BCBA concentrated), 1,300 (BCaBA supervised), 1,000 (BCaBA concentrated, pre-2027), or 800 (BCaBA concentrated, 2027). Eight pathways, five totals, all within five consecutive years.

Where it comes from BCBA Handbook (updated 06/2026); BCaBA Handbook (updated 06/2026); 2027 BCBA Requirements (updated 02/2026) and 2027 BCaBA Requirements (03/2025)

Activities that never count

Neither restricted nor unrestricted

Work that isn't fieldwork at all, however useful it is.

MoreLess about Activities that never count

Conferences, workshops, and university courses; coursework; studying for the exam; meetings with little behavior-analytic content; nonbehavioral admin such as scheduling and billing; CPR and crisis trainings; nonbehavioral assessments; interventions that aren't behavior-analytic; and role-play that isn't tied to a real client. All fieldwork must be tied to a specific, real client.

Where it comes from BCBA Handbook (updated 06/2026); the real-client rule: the BACB's August 2025 handbook update

Supervision 4

Fieldwork supervision percentage

5% or 10% each month (7.5% BCBA concentrated, 2027)

The share of each month's fieldwork hours that must be supervised.

MoreLess about Fieldwork supervision percentage

Supervised hours divided by the month's total fieldwork hours. At least 5% on supervised fieldwork and 10% on concentrated, except BCBA concentrated under the 2027 standards at 7.5% (BCaBA concentrated stays at 10%). It is measured every supervisory period, one calendar month, never as a running total, so a strong month can't make up for a short one. Supervised hours include supervision meetings and the activities your supervisor observes.

In the app Your dashboard shows the month's supervision percentage against your pathway's minimum as you log.

Where it comes from BCBA Handbook (updated 06/2026), supervision requirements and glossary (p. 69); BCaBA Handbook (updated 06/2026)

Observation

Monthly · 60 or 90 minutes from 2027

Your supervisor watching you work with a client.

MoreLess about Observation

Every supervisory period, your supervisor must observe you with the clients you serve. Under the pre-2027 standards that is at least one observation a month. Under the 2027 standards it is measured in minutes added up across the month: at least 60 minutes on supervised fieldwork and 90 minutes on concentrated.

Where it comes from BCBA Handbook (updated 06/2026), structure of supervision interactions (p. 20); 2027 BCBA Requirements (updated 02/2026) and 2027 BCaBA Requirements (03/2025)

Group supervision

2 to 10 trainees

A supervision meeting with 2 to 10 trainees together.

MoreLess about Group supervision

The BACB states the balance two ways, each with its own base:

  • “At least 50% of the supervision meeting time must be individual supervision each supervisory period.”
  • “Group supervision hours may not exceed half of the total supervised hours in each supervisory period.”

A group never has more than 10 trainees, however many supervisors are there. Unless you're supervised at an organization with several supervisors, your group supervision comes from the supervisor who gives your individual supervision. Each group hour is still restricted or unrestricted, like any other hour.

In the app ABA FT checks the second sentence: the month's group hours against half of its supervised hours. It doesn't check meeting time, so talk the first sentence through with your supervisor.

Where it comes from BCBA Handbook (updated 06/2026), structure of supervision interactions (p. 20); BCaBA Handbook (updated 06/2026) (p. 17)

Supervision contact

Four or six a month, pre-2027

A supervisor and trainee meeting, counted each month under the pre-2027 standards.

MoreLess about Supervision contact

Under the pre-2027 standards, supervised fieldwork needs at least four supervisor contacts a month and concentrated needs six. The 2027 standards drop the contact count: the BACB announced in its March 2022 newsletter that the supervision percentage already covers it. The handbooks' supervision section still mentions four and six and hasn't caught up yet.

Where it comes from Pre-2027: BCBA Handbook (updated 06/2026) and BCaBA Handbook (updated 06/2026). 2027: BACB Newsletter, March 2022 (p. 5 BCBA, p. 9 BCaBA)

Months, timing and forms 6

Supervisory period

One calendar month

The window each month's requirements are measured in: one calendar month.

MoreLess about Supervisory period

Fieldwork is measured month by month. The supervision percentage, the 20-hour minimum, the monthly cap, observation, and (under the pre-2027 standards) contacts are all judged inside each calendar month. Your unrestricted share and your total hours add up across all of fieldwork.

Where it comes from BCBA Handbook (updated 06/2026); BCaBA Handbook (updated 06/2026)

Monthly hour minimum

20 hours a month

The fewest fieldwork hours a month needs to count.

MoreLess about Monthly hour minimum

A month needs at least 20 fieldwork hours. Under 20, the month earns no eligible hours at all: it is a floor, not a proration.

Where it comes from BCBA Handbook (updated 06/2026), accrual of fieldwork; BCaBA Handbook (updated 06/2026)

Monthly hour cap

130 pre-2027 · 160 from 2027

The most fieldwork hours that can count in one month.

MoreLess about Monthly hour cap

130 hours a month under the pre-2027 standards and 160 under the 2027 standards, for both fieldwork types. You can work more, but no more than the cap counts that month.

In the app Your month's hours show against your pathway's cap as you log, and hours over it are flagged. Your entries always save.

Where it comes from BCBA Handbook (updated 06/2026), accrual of fieldwork; 2027 BCBA Requirements (updated 02/2026) and 2027 BCaBA Requirements (03/2025)

Fieldwork window

Five consecutive years

All of your fieldwork hours must fall within five consecutive years.

MoreLess about Fieldwork window

Under both the pre-2027 and the 2027 standards, every pathway's hours must be accrued within five consecutive years. A slower pace is fine, as long as each month you count has at least 20 hours and everything fits inside the window.

Where it comes from BCBA Handbook (updated 06/2026); BCaBA Handbook (updated 06/2026)

Monthly Fieldwork Verification Form (M-FVF)

Signed by the end of the next month

The form you and your supervisor sign for each month of fieldwork.

MoreLess about Monthly Fieldwork Verification Form

One form per supervisor, or per organization when several supervisors work together there. You and your supervisor sign it by the last day of the calendar month after the month of supervision, or no hours count for that month. You and your supervisor keep it for at least seven years; it isn't sent with your application. Applying on or after January 1, 2027? Use the 2027 forms.

In the app Your supervisor reviews and signs each month's form in the app.

Where it comes from BCBA Handbook (updated 06/2026), verification forms; Monthly Fieldwork Verification Forms (2022 forms v 08/2023, 2027 forms v 06/2026)

Final Fieldwork Verification Form (F-FVF)

Sent with your application

The form that sums up a supervision relationship, sent with your application.

MoreLess about Final Fieldwork Verification Form

Signed at the end of each supervision relationship. Supervised and concentrated hours go in separate sections, always as the actual hours accrued. It is submitted with your certification application.

Credentials and standards 4

BCBA

Graduate level

Board Certified Behavior Analyst: the graduate-level credential for independent practice.

MoreLess about BCBA

Earned with a graduate degree, fieldwork (2,000 hours supervised or 1,500 concentrated), and the exam. BCBAs practice independently, renew with 32 CEUs every two years, and can supervise BCaBAs, RBTs, and fieldwork trainees once they meet the supervisor requirements.

Where it comes from BCBA Handbook (updated 06/2026)

BCaBA

Bachelor's level

Board Certified Assistant Behavior Analyst: the bachelor's-level credential, practicing under a BCBA.

MoreLess about BCaBA

Earned with a bachelor's degree, fieldwork (1,300 hours supervised, or concentrated: 1,000 pre-2027 and 800 under the 2027 standards), and the exam. BCaBAs practice with ongoing BCBA oversight and can supervise RBTs.

Where it comes from BCaBA Handbook (updated 06/2026)

RBT

Supervised practice

Registered Behavior Technician: the credential for delivering ABA services under supervision.

MoreLess about RBT

RBTs deliver behavior-analytic services, with ongoing supervision every month they provide services. To earn it: be 18 or older with a high school education or equivalent, pass a background check and an abuse registry check, complete the 40-hour training and an Initial Competency Assessment, and pass the exam. It is kept with 12 PDUs every two years. RBT service hours don't automatically count as BCBA or BCaBA fieldwork.

Where it comes from RBT Handbook (06/2026)

The 2027 standards

Takes effect January 1, 2027

The BACB's updated fieldwork rules, in effect from January 1, 2027.

MoreLess about the 2027 standards

Which standards apply is decided by when the BACB receives your complete application, not when your fieldwork started: received by December 31, 2026, the pre-2027 standards; after that, the 2027 standards. The 2027 standards raise the monthly cap from 130 to 160 hours, measure observation in minutes (60 supervised, 90 concentrated), drop the contact count, lower BCBA concentrated supervision from 10% to 7.5%, and lower the BCaBA concentrated total from 1,000 to 800 hours. RBT ongoing supervision doesn't change.
