BCBA Concentrated vs. Supervised Fieldwork: Which Option Is Better?
Before you can apply for BCBA certification, you have to complete supervised fieldwork hours. The BACB offers two ways to accrue those hours: Supervised Fieldwork and Concentrated Supervised Fieldwork. You can complete all your hours under one type or combine both during your fieldwork experience.
At first glance, Concentrated Supervised Fieldwork may seem like the obvious choice because it requires 500 fewer hours. After all, fewer hours should mean finishing sooner, right? Maybe. But there's much more to it. Let’s look at what each option involves—and how to decide which one fits your situation.
Supervised Vs Concentrated BCBA Fieldwork: 2027 Standards
The comparison below reflects the 2027 BCBA requirements. The requirements that apply to you depend on when the BACB receives your complete certification application.
To be evaluated under the 2022 requirements, your complete application must be received by December 31, 2026. Applications received on or after January 1, 2027 must meet the new requirements.
If you’re unsure when you’ll apply, the BACB recommends working with your supervisor to meet both sets of requirements and maintaining the appropriate documentation for each. Because 2027 is right around the corner, the requirements outlined in this article are based on the 2027 standards.
Requirement | Supervised Fieldwork | Concentrated Supervised Fieldwork |
Total fieldwork hours | 2,000 | 1,500 |
Required supervision | 5% of fieldwork hours | 7.5% of fieldwork hours |
Fieldwork allowed per calendar month | 20–160 hours | 20–160 hours |
Observation with a client per month | 60 cumulative minutes | 90 cumulative minutes |
Individual supervision | At least 50% of supervised hours | |
Unrestricted activities | At least 60% of total fieldwork | |
Who Can Supervise Your Fieldwork?
Your supervisor(s) must be one of the following:
An active BCBA with no current disciplinary sanctions, certified for at least one year, and meeting the ongoing supervision CEU requirement; OR
An active BCBA with no current disciplinary sanctions, certified for less than one year, and receiving monthly consultation from a qualified consulting supervisor
Supervisors must also complete the required eight-hour supervision training. Additionally, if your BCBA is supervising remotely, ensure they have state licensure to do so, if applicable.
What Both Fieldwork Paths Have in Common
Although the two options differ in total hours and supervision intensity, several fieldwork requirements apply to both.
You can accrue between 20 and 160 total fieldwork hours per calendar month. That encompasses both supervised and independent hours.
At least 50% of your supervised hours must be individual supervision. Group supervision is optional and can account for no more than 50%.
At least 60% of your total fieldwork hours must involve unrestricted activities.
All qualifying hours must be completed within five continuous years.
Fieldwork activities must be behavior analytic and connected to specific client programming.
You and your supervisor must maintain the required contracts, verification forms, and supporting documentation for seven years.
Unrestricted activities are client-specific tasks that involve building BCBA-level competencies. For example, trainees could accrue unrestricted hours conducting assessments, analyzing data, developing or revising programs, training caregivers or staff, reviewing research relevant to client programming, and writing behavior-analytic reports.
The 60% unrestricted requirement applies across your total fieldwork experience, so you don't necessarily need to reach exactly 60% every month. However, you should monitor the percentage regularly so you aren’t trying to make up a large number of unrestricted hours near the end.
TIP: If you complete all your hours as Supervised Fieldwork, stop tracking restricted hours when you reach 800/2,000. If you complete all your hours as Concentrated Supervised Fieldwork, stop tracking restricted hours when you reach 600/1,500.
What is Supervised Fieldwork?
Supervised Fieldwork is the 2,000-hour option. This option requires more total hours, but it has a lower monthly supervision requirement.
At least 5% of the fieldwork hours you accrue during each calendar month must be supervised. For example, if you complete 100 qualifying fieldwork hours in one month, you need at least five hours of qualifying supervision:
100 fieldwork hours × 5% = 5 supervised hours
Your supervisor must also observe you working with one or more clients for at least 60 cumulative minutes during the month. You can meet this requirement through one 60-minute observation or multiple shorter observations that total at least 60 minutes.
Client observation is only one component of supervision. The remainder may include individual meetings, group supervision, and/or additional client observations. Remember that at least 50% of your total supervised time must be individual supervision.
Supervised Fieldwork may be a good fit when:
Your supervisor cannot consistently provide the higher level of supervision required for concentrated fieldwork.
You pay for supervision privately and need a lower monthly supervision requirement.
You want more time to develop your skills across different clients, activities, or settings.
A longer fieldwork timeline fits your academic, employment, and personal commitments.
The primary tradeoff is time. You must complete 500 more actual fieldwork hours than someone who completes their entire experience under the concentrated option.
Remember, fieldwork is a journey toward competence—not a sprint to collect hours. The goal isn't simply to finish faster, but to finish prepared.
What is Concentrated Supervised Fieldwork?
Concentrated Supervised Fieldwork is the 1,500-hour option. It requires 500 fewer fieldwork hours than Supervised Fieldwork, but it comes with a higher monthly supervision requirement and more client-observation time.
Beginning in 2027, at least 7.5% of the hours accrued during each calendar month must be supervised. For example, if you complete 100 fieldwork hours in one month, you'd need at least 7.5 hours of supervision. Your supervisor would also need to observe you with a client for at least 90 cumulative minutes.
Concentrated fieldwork may be a good fit when:
You have reliable access to a qualified supervisor who can provide the higher-intensity supervision
Your organization has a structured fieldwork or practicum program.
You can consistently schedule the required supervision and client observations.
The additional supervision is affordable or included with your employment or academic program.
You want to complete fewer total fieldwork hours and can consistently meet the concentrated requirements.
The tradeoff is intensity. Concentrated fieldwork requires more supervisor involvement each month and tighter scheduling.

How Many Supervision Hours Will You Need?
Under the 2027 requirements, your BCBA will need to supervise you for at least 5% of your total monthly fieldwork hours. Concentrated Supervised Fieldwork requires at least 7.5%.
You must meet the applicable percentage within each month. Receiving additional supervision in one month does not make up for a shortfall in another.
Fieldwork Hours (Monthly) | Number of Supervised Hours (Monthly) | |
Supervised Path | Concentrated Supervised Path | |
40 | 2 hours | 3 hours |
80 | 4 hours | 6 hours |
100 | 5 hours | 7.5 hours |
120 | 6 hours | 9 hours |
160 | 8 hours | 12 hours |
At an average of 100 fieldwork hours per month, Supervised Fieldwork would take approximately 20 months to reach 2,000 hours. Concentrated Supervised Fieldwork would take approximately 15 months to reach 1,500 hours.
Which Option Is Better?
Neither option is universally better. The right choice is the one you can complete consistently, ethically, and with meaningful supervision. Consider the following questions before deciding:
How dependable is your access to supervision? Concentrated fieldwork only works when your supervisor can reliably provide enough qualifying supervision and client observation time.
Does your supervisor have capacity to support concentrated supervised fieldwork? Ask your supervisor whether they can realistically provide the required time, observations, feedback, and oversight throughout your experience.
Who pays for supervision? If your employer includes supervision, concentrated fieldwork may be financially practical. If you pay privately, compare the full projected cost of each option—not just the monthly rate.
What is the quality of the supervision? More supervision is only valuable when it's meaningful. Don't choose concentrated fieldwork solely because it appears faster if the available experience is narrow or poorly organized.
Which option fits your schedule? Consider whether you can reliably meet the monthly requirements alongside your academic, employment, and personal responsibilities.
Can you combine the two types?
Yes. The BACB allows trainees to accrue both Supervised Fieldwork and Concentrated Supervised Fieldwork.
Here's an example. Imagine a trainee meets the concentrated requirements from January through March. If the trainee meets only the Supervised Fieldwork requirements in April and May, those months may be documented as Supervised Fieldwork instead. The trainee could return to concentrated fieldwork in June if all concentrated requirements are met that month.
When the two types are combined, Concentrated Supervised Fieldwork hours have approximately 1.33 times the value of Supervised Fieldwork hours when calculating progress toward the combined requirement.
Let's break that down because it can get a little confusing.
(Concentrated Supervised Fieldwork hours × 1.33) + Supervised Fieldwork hours = progress toward the 2,000-hour equivalent
Only use the multiplier for months that you met concentrated hour requirements.
Example: Combining Both Fieldwork Types
Month | Fieldwork type | Actual hours accrued | Multiplier | Hours toward the 2,000-hour equivalent |
January | Concentrated | 100 | × 1.33 | 133 |
February | Concentrated | 100 | × 1.33 | 133 |
March | Concentrated | 100 | × 1.33 | 133 |
April | Supervised | 100 | × 1 | 100 |
May | Supervised | 100 | × 1 | 100 |
June | Concentrated | 100 | × 1.33 | 133 |
Total | Mixed | 600 actual hours | — | 732 weighted hours |
In this example, the trainee completed 600 actual fieldwork hours. Because four months met the Concentrated Supervised Fieldwork requirements, 400 hours received the 1.33 multiplier:
(400 × 1.33) + 200 = 732 equivalent hours
The trainee has therefore accrued 732 weighted hours toward the combined 2,000-hour equivalent.
What If a Month Doesn’t Meet the Concentrated Requirements?
Your fieldwork type is determined each month separately. If one month doesn't meet the concentrated requirements but does meet every applicable Supervised Fieldwork requirement—including at least 5% supervision and 60 cumulative minutes of client observation—that month's hours can be counted as Supervised Fieldwork.
The Bottom Line
Concentrated Supervised Fieldwork requires 500 fewer fieldwork hours, but it comes with more intensive monthly supervision and client-observation requirements. Supervised Fieldwork requires more total hours but may offer greater flexibility and a lower monthly supervision commitment.
Your decision also doesn't have to be permanent. You can combine the two fieldwork types as your circumstances change, provided each month meets the requirements for the category under which it's counted. Before deciding, review your plan with your supervisor and confirm that it aligns with the requirements that will apply when you submit your application.
