Students interested in meeting the fieldwork requirement may do so through two possible pathways. On the one hand, they may complete 2,000 hours of Supervised Fieldwork, and on the other, 1,500 hours of Concentrated Supervised Fieldwork. It is important to consider that these options may be modified as of January 1, 2027, due to the new set of certification application requirements. Therefore, the application submission date, rather than the date on which the hours were logged, will be considered the determining criterion.
Additionally, fieldwork is one of the fundamental components of the certification pathway, alongside the graduate degree, behavior-analytic coursework, and the examination. To learn about the complete process, see our guide on how to become a BCBA.
Current BCBA Fieldwork Requirements at a Glance
Under the requirements in effect in 2026, applicants may accumulate their fieldwork hours through Supervised Fieldwork, Concentrated Supervised Fieldwork, or a combination of both, provided that the hours recorded meet the conditions established by the BACB.
The following table presents other current fieldwork requirements and details.
| Requirements | Supervised Fieldwork | Concentrated Supervised Fieldwork |
|---|---|---|
| Total hours | 2,000 hours | 1,500 hours |
| Hours permitted per month | 20 to 130 hours | 20 to 130 hours |
| Required supervision per month | 5% of the hours | 10% of the hours |
| Minimum contacts with the supervisor | 4 per month | 6 per month |
| Observation with a client | Minimum of 1 per month | Minimum of 1 per month |
| Individual supervision | 50% or more of supervised hours | 50% or more of supervised hours |
| Group supervision | No more than 50% of supervised hours | No more than 50% of supervised hours |
| Unrestricted activities | At least 60% of the total | At least 60% of the total |
| Supervisory period | One calendar month | One calendar month |
| Time frame for completing fieldwork | 5 continuous years | 5 continuous years |
| Forms | Monthly and Final Fieldwork Verification Forms | Monthly and Final Fieldwork Verification Forms |
This information corresponds to the requirements in effect in the BCBA Handbook version updated in June 2026.
The unrestricted activity requirement is cumulative. In other words, it is not mandatory to reach 60% each month. What matters is that the total number of hours submitted includes at least 60% unrestricted activities.
To avoid complications, it is advisable to actively monitor these proportions. This is important because a trainee who accumulates mostly restricted hours at the beginning may have difficulty reaching the required proportion later.
What Are Restricted and Unrestricted Activities?
Restricted activities involve applying procedures directly with a client, whereas unrestricted activities involve evaluating, analyzing, planning, and even training caregivers and professionals.
An example of a restricted activity would be implementing a skill-acquisition program or carrying out a previously designed intervention plan.
By contrast, analyzing data to determine whether a program needs changes or conducting a behavioral assessment are examples of unrestricted activities. These may be more closely aligned with the types of responsibilities and roles a professional may assume after obtaining BCBA certification.
The classification of activities as restricted or unrestricted cannot always be determined by whether they are performed directly with a client. For example, data collection may be considered unrestricted when it is part of an assessment or program analysis, but it may be restricted when it occurs in the context of implementing a treatment. What ultimately matters is the purpose of the task and the function it serves within the services provided.
For this reason, before recording an activity, individuals completing fieldwork should consult the current definitions and examples in the BCBA Handbook and review them with their supervisors.
It should not be forgotten that 60% of the total fieldwork hours must consist of unrestricted activities. This requirement is cumulative, not monthly.
Supervised Fieldwork Vs. Concentrated Supervised Fieldwork
The criteria that distinguish these two options are the total number of hours and the intensity of supervision.
Concentrated Supervised Fieldwork requires fewer hours than Supervised Fieldwork. However, it requires a higher monthly supervision percentage.
Under the requirements in effect as of June 2026:
- Supervised Fieldwork requires 2,000 hours and supervision equal to 5% of the monthly hours.
- Concentrated Supervised Fieldwork requires 1,500 hours and supervision equal to 10% of the monthly hours.
Supervised Fieldwork may be a more practical option when supervisor availability is limited or when such intensive supervision cannot be provided.
From a scheduling perspective, Concentrated Supervised Fieldwork may allow fieldwork to be completed in less time, but this does not depend solely on having to accumulate 500 fewer hours. For this option to be truly viable, the trainee needs consistent access to a qualified supervisor and opportunities to complete activities that meet BACB requirements. This option may fit better within structured practicums or a university experience.
Choosing between these two options is a decision that should not be based only on which one appears faster. It should instead depend on the type of structure involved, whether it can be sustained over time without compromising the quality of the experience, and whether the required monthly commitment can be maintained. Neither option is superior to the other.
Although the BCBA Handbook also allows both types of fieldwork to be used, the hours are not combined interchangeably. They must be completed within each supervision structure. This means that, within the same month, hours may only be recorded under one type and must meet all of the corresponding conditions.
To calculate the total, the BACB applies specific procedures that weight Concentrated Supervised Fieldwork hours before adding them to Supervised Fieldwork hours.
Any combination should be planned and reviewed with the supervisor using the current version of the Handbook.
Who Can Supervise BCBA Fieldwork?
Only professionals who meet the requirements established by the BACB may assume the role of fieldwork supervisor. In these cases, holding BCBA certification is not sufficient on its own.
Those interested in supervising must maintain active BCBA certification, have no current disciplinary sanctions, and have completed the required eight-hour supervision training.
Those who are in their first year of certification may serve as fieldwork supervisors, provided that they meet monthly with a qualified Consulting Supervisor. Those who have been certified for one year or longer must meet the ongoing supervision education requirements established by the BACB.
These conditions can be verified through the BACB Certificant Registry, which displays the supervisors’ certification dates and status. This helps students determine whether the professional guiding them is qualified to assume the role and meets the relevant training conditions.
Once this has been verified, the supervision relationship must be formalized through a contract signed before any activity begins or any hours are recorded. Without it, the practice hours and any intervention will be invalidated and may not be counted retroactively as fieldwork.
In addition to these requirements, there is an especially sensitive and relevant rule. During the fieldwork period, the BACB prohibits certain relationships between the practitioner and supervisor, as these may affect the objectivity of the training period. The supervisor may not be a family member, be subordinate to the trainee, or be employed by the trainee. These conditions must also be verified before the contract is signed.
How BCBA Supervision Is Measured and Documented
In fieldwork, simply accumulating a certain number of hours is not enough. During this process, it is also necessary to meet the client observation requirement, complete the required monthly supervision percentage, and maintain the corresponding documentation.
For each supervision structure, every calendar month is reviewed as a separate supervision period. In other words, a month may include enough total hours and still require an adjustment.
Likewise, at least 50% of the supervised hours must be individual; therefore, group supervision cannot exceed that percentage. If any of these criteria are not met, the hours accrued during that month may be reduced or may not be counted.
The BACB considers that all fieldwork hours, both independent hours and those completed while the supervisor was present, must be added together in full at the end of each calendar month.
The supervision percentage is calculated from that total, including both group and individual supervision, in relation to the total hours accumulated during the month. The result must equal 5% monthly supervision for Supervised Fieldwork and 10% for Concentrated Supervised Fieldwork.
An example of Supervised Fieldwork would be a trainee who accrues 100 hours during one month and needs at least 5 supervised hours. Of those hours, 2.5 must be individual, while the remainder may be group supervision. Group supervision must not exceed 50%.
By contrast, in Concentrated Supervised Fieldwork, the trainee accrues 100 hours during one month and needs at least 10 supervised hours. Of those hours, 5 must be individual, and group supervision cannot exceed 5 hours.
For both Supervised Fieldwork and Concentrated Supervised Fieldwork, the observation and supervisor-contact requirements must also be met during that month.
At the end of each period, the trainee and supervisor must review the records and complete the Monthly Fieldwork Verification Form (M-FVF). It must be signed no later than the last day of the calendar month.
At the end of the fieldwork period, both parties must complete the Final Fieldwork Verification Form (F-FVF). The total number of hours reported on the F-FVF cannot exceed the sum of the hours documented on the signed M-FVFs.
Trainees and supervisors must retain the supervision contract, all signed verification forms, and the supporting documentation system for at least seven years from the final supervision meeting.
What Changes for BCBA Fieldwork on January 1, 2027?
During this transition, the decisive date is the date on which the certification application is submitted. This means that if a student submits an application on January 1, 2027, or after that date, both the hours completed during 2026 and the supporting forms may need to meet the 2027 requirements.
Completed hours are not excluded. Before submitting the application, the student should review the BACB guidelines and confirm with their supervisor which requirements and documentation apply and how they should be completed.
For this reason, planning hours without considering the application date may create difficulties when it is time to document them.
| Fieldwork requirement | Current requirements for applications submitted before 2027 | Requirements for applications submitted on or after January 1, 2027 |
|---|---|---|
| Hours per month | Minimum of 20 and maximum of 130 | Minimum of 20 and maximum of 160 |
| Supervision for Supervised Fieldwork | 5% of monthly hours | 5% of monthly hours |
| Supervision for Concentrated Supervised Fieldwork | 10% of monthly hours | 7.5% of monthly hours |
| Contacts with the supervisor | 4 for Supervised and 6 for Concentrated | The separate minimum number of contacts is eliminated |
| Observation with a client | At least one observation per month | 60 cumulative minutes for Supervised and 90 minutes for Concentrated |
| Individual supervision | At least 50% of supervised hours | At least 50% of supervised hours |
| Unrestricted activities | At least 60% of total hours | At least 60% of total hours |
The new requirements allow greater flexibility in the number of hours that may be recorded each month, reduce the supervision intensity for the concentrated option, and replace the minimum number of contacts with an observation requirement based on the trainee’s cumulative time. The percentages for individual supervision and unrestricted activities remain the same.
Individuals who submit their applications under the 2027 rules must use one of the following sets of forms:
When the exact application date is still unclear, it is prudent to organize the fieldwork and its documentation so that they can be reviewed against both the 2026 and 2027 requirements.
This involves continuously monitoring the expected application date, recording the duration of observations, and reviewing with the supervisor which forms must be completed during each period.
Common Mistakes That Can Cost Fieldwork Hours
Most fieldwork errors result from small monthly compliance issues, such as incomplete documentation or an incorrectly reviewed requirement, rather than major criteria such as the total number of hours recorded.
Reviewing fieldwork continuously makes it possible to identify these problems before they affect the hours submitted for certification.
Some of the most common mistakes include:
- Beginning to record hours before starting the corresponding academic training
Hours may be counted after attending the first class meeting of the behavior-analytic course, provided that a qualified supervisor is in place and the supervision contract has been signed. The course must subsequently be passed for those hours to be valid. - Beginning fieldwork without a signed supervision contract.
Any hours accrued before a contract is signed cannot be counted retroactively as fieldwork. - Accumulating too many restricted activities at the beginning.
Because 60% of the total fieldwork must consist of unrestricted activities, an initial imbalance may be difficult to correct later. - Failing to reach the monthly supervision percentage.
If supervision is insufficient, the eligible hours for that month may be reduced. In the case of Concentrated Supervised Fieldwork, the hours cannot be prorated or adjusted. - Failing to complete the required contacts or observations.
Under BACB requirements, a month without the required observation does not generate eligible fieldwork hours. Each month must meet the required number of supervision contacts and include the mandatory observation with a client. - Recording fewer than 20 hours or exceeding the monthly maximum.
A month with fewer than 20 fieldwork hours does not generate eligible hours, and any hours exceeding the applicable monthly maximum cannot be carried over to another month. - Using forms that do not correspond to the application date.
The M-FVF and F-FVF must align with both the supervision structure used and the requirements in effect when the complete application is submitted. - Relying exclusively on employment or payroll records.
Although these records demonstrate that the work was performed, they do not verify the activity categories, supervision received, observations, or compliance with BACB requirements. - Assuming that all RBT hours count.
Only activities that meet the fieldwork requirements count. - Failing to monitor the cumulative proportion of unrestricted hours.
Records should be reviewed carefully and regularly throughout the process, as imbalances in recordkeeping and hour accrual may be difficult to correct later. - Waiting until the end of the process to review the records.
Planning ahead and consistently monitoring the process helps prevent misclassified activities, incorrectly recorded hours, incomplete documentation, and other issues related to the fieldwork process. - Failing to obtain signatures within the established time frame.
Missing or late signatures may prevent the hours accrued during that period from being accepted.
The monthly consequences depend on which requirement was not met. Not every error automatically results in the loss of all hours for that month, although some do.
How to Track Your BCBA Fieldwork
Fieldwork tracking is more than simply adding up hours. Its purpose is to monitor the quality of the process, keep students’ records up to date, and allow them and their supervisors to detect misclassified activities, pending observations, or any other errors that may occur.
According to the Handbook, it is advisable to record the following information for each fieldwork activity:
- Date, start time, and end time.
- Fieldwork type: Supervised Fieldwork or Concentrated Supervised Fieldwork.
- Name of the responsible supervisor.
- Whether the hours were independent or supervised.
- Activity category: restricted or unrestricted.
- Supervision type: individual or group.
- A brief description of the fieldwork activity.
- A summary of the supervision, including feedback provided or progress toward training goals.
- The date, duration, and context of each observation with a client.
- The total fieldwork hours accrued during the month.
- The total supervised hours and monthly supervision percentage.
- The number of supervisor-trainee contacts completed during the month, when required.
- The monthly distribution between individual and group supervision.
- The cumulative percentage of unrestricted activities.
- The applicable M-FVF version, its review status, and the date it was signed by both parties.
- The setting or organization where the activity occurred, when applicable.
Because the BACB does not require a specific tracking tool, a spreadsheet, application, or other tracking system may be used, provided that the records are complete, remain up to date, and make it possible to effectively prepare the Final Fieldwork Verification Form (F-FVF).
Where Fieldwork Fits Within the BCBA Certification Pathway
Within the certification process, fieldwork is the practical component involving preparation and supervised training for obtaining the BCBA credential. It must be integrated with a graduate degree and academic education in behavior analysis.
Once the student meets all eligibility requirements, they must still submit the application and pass the examination.
The complete pathway is outlined in the guide on how to become a BCBA.
In many cases, completing the hours does not occur as a separate stage. The student may begin after attending the first class of a qualifying behavior-analytic course, passing that first course, and having a qualified supervisor with a signed contract. In this way, hours may be accumulated while completing a master’s program or working in an applied behavior analysis setting.
It is important to note that ABA master’s programs are not all the same and do not manage fieldwork in the same way. Some include practicum experiences and supervision within the program, others help coordinate them, and others delegate these responsibilities to students. This information should be verified with each institution rather than assuming a general rule.
Finally, obtaining BCBA certification does not replace each state’s professional requirements. In some jurisdictions that regulate practice through licensure, individuals may be required to complete an additional process before beginning to practice. State BCBA licensure is therefore a separate process that must be reviewed after certification.
Frequently Asked Questions
Can I Begin BCBA Fieldwork Before Completing My Academic Training?
Yes. It is not necessary to complete all academic training before beginning fieldwork. Under Pathways 1 and 2, trainees may begin accruing hours after attending the first class meeting of their initial qualifying graduate-level course in behavior analysis, provided they already have a qualified supervisor and a signed supervision contract. They must subsequently pass that course with the required grade for the accrued hours to count.
Do My Paid RBT Hours Count Toward BCBA Fieldwork?
RBT hours may count, but the fact that they are paid does not automatically make them fieldwork. What matters is that each activity meets BACB criteria, is connected to behavior-analytic services, occurs under supervision, and is properly documented. Many routine RBT tasks and ongoing supervision activities may not count or may be classified as restricted.
What Happens to the Hours I Complete in 2026 if I Submit My Application in 2027?
Those hours may need to meet the requirements in effect on the date the application is submitted. This means that hours accumulated in 2026 may need to comply with the 2027 conditions and documentation requirements if the application is submitted on or after January 1, 2027. Applicants should review the current BACB guidance and verify with the BACB and their supervisor which requirements apply to their fieldwork and documentation.
Can My Employer Supervise My BCBA Fieldwork?
Yes, provided that a qualified BCBA is authorized to serve as a supervisor and has the necessary relationship with the clients. The BACB does not prohibit the trainee’s employer, or a BCBA working within the same organization, from supervising their fieldwork. The restriction in this case applies only in the opposite direction, meaning when the supervisor is employed by the trainee.
Can a Family Member Supervise My BCBA Fieldwork?
No. The BACB prohibits a person who is related to the trainee from acting as their fieldwork supervisor, even if that person meets all other required qualifications.
How Long Does It Take to Complete 1,500 Hours of Concentrated Supervised Fieldwork?
There is no single time frame. It depends on the number of hours that can be accumulated each month, supervisor availability, and access to unrestricted activities.
Under the 2027 requirements, reaching 160 hours each month would allow the total to be completed in approximately nine months. However, this estimate does not account for interruptions, noncompliant months, vacations, or lack of supervision.
Do I Need Different Forms if I Submit My Application in 2027?
Yes. Applications must comply with the 2027 requirements, using the 2027 Monthly and Final Fieldwork Verification Forms. The form must also correspond to the supervision structure, whether it involves an individual supervisor or multiple supervisors within an organization. Outdated forms will not be accepted.
