One of the most important steps toward becoming a Board Certified Behavior Analyst® (BCBA®) is completing supervised fieldwork. During fieldwork, students gain hands-on experience applying behavior-analytic principles in real-world settings while working under the guidance of a qualified supervisor. 

While Applied Behavior Analysis (ABA) fieldwork may seem complex at first, understanding the process early can help you plan ahead and approach fieldwork with confidence. 

Why ABA fieldwork matters

ABA professionals support learners from infancy through adulthood with mild to intensive instructional needs in reaching individualized goals across academic, communication, social, and daily living areas. 

While responsibilities may differ depending on the setting, ABA roles are built on the same foundation. All rely on the principles of behavior analysis and require professionals who can adapt evidence-based practices to meet learners’ needs.

In any setting, behavior analyst jobs involve: 

• Building real-world clinical and professional skills
• Learning to apply behavior-analytic concepts beyond coursework
• Developing confidence around working with clients and teams
• Gaining exposure to different populations, settings, and service models
• Developing ethical decision-making skills
• Gaining experience in communicating with families, supervisors, and other professionals

BCBA fieldwork at a glance

ABA students seeking BCBA certification have two main options when it comes to fieldwork: 2,000 hours of supervised fieldwork, or 1,500 hours of concentrated supervised fieldwork.  

Students are expected to log anywhere between 20 and 160 hours of fieldwork per month, and receive ongoing supervision and feedback throughout their time in the field. At least 60% of BCBA fieldwork hours must be unrestricted activities, and students are expected to log at least one observation with a client each month.  

Note: Certification requirements are determined by the Behavior Analyst Certification Board (BACB) and may change over time. Students should always consult current BACB guidance and program faculty for the most up-to-date information. 

What counts toward fieldwork (and what doesn’t)

Unrestricted activities (at least 60%)

Unrestricted activities include many of the tasks that a professional BCBA ® can expect to handle day-to-day, including:

• Conducting assessments
• Analyzing and graphing data
• Writing behavior plans and reports
• Training staff or caregivers
• Meeting with clients

Restricted activities (up to 40%)

Restricted activities may account for up to 40% of fieldwork hours and typically involve the direct implementation of behavior-analytic interventions with clients. 

What doesn’t count as fieldwork

The following activities generally do not count toward BCBA fieldwork hours:

• Coursework or homework
• Conferences or general trainings
• Administrative or non-ABA tasks
• Services not based in behavior analysis

Understanding BCBA fieldwork supervision

Don’t worry, you won’t tackle fieldwork alone! To count toward your required hours, supervision must be provided by a qualified BCBA with supervision training. 

Types of supervision

There are two primary types of supervision: individual supervision and group supervision. Most students will experience a combination of both throughout their fieldwork. 

Finding a fieldwork supervisor

Supervision is often provided through a student’s practicum site. However, students enrolled in Ohio State’s Applied Behavior Analysis master’s program may also have access to qualified supervisors through the program. This benefit can provide complimentary supervision for up to 100 fieldwork hours per month, totaling as many as 600 hours throughout the program. 

What to expect each month

• Regular contact with your supervisor
• Ongoing feedback on your performance
• At least one observation with a client

Why BCBA fieldwork supervision matters 

Supervision is a key component of your ABA training, and helps to: 

• Build clinical skills
• Develop ethical decision-making
• Ensure high-quality client care — after all, you’re still learning!

Completing fieldwork in Ohio State’s online Applied Behavior Analysis master’s program

Ohio State’s online ABA master’s program is designed to support students throughout the process. With local practicum placement assistance, access to supervision, and opportunities to apply learning in real-world settings, students gain valuable experience while working toward their professional goals. There are five key steps to complete before you can begin your ABA fieldwork: 

Step 1: Find a practicum site

Students are responsible for securing their own practicum placements where they can accrue a minimum of 20 hours per month. However, our program has many local connections with practicum sites and can support students in the greater Columbus area as they search for practicum opportunities. Faculty also work with students who already have supervision arrangements in place. 

Step 2: Submit an affiliation agreement 

An affiliation agreement must be signed before the practicum begins and renewed annually. 

Step 3: Confirm fieldwork placement with faculty  

A faculty member will review and confirm your placement before fieldwork begins. 

Step 4: Complete required evaluations  

Students participate in two evaluations throughout the year: one evaluating the supervisor and one evaluating the trainee. 

Step 5: Enroll in fieldwork course  

Students complete ESSPED 8189: Field Experience in Special Education twice during the program, earning a total of six credit hours. 

Beyond fieldwork hours 

In addition to accruing supervised fieldwork hours, many students use their practicum experiences to support preliminary research projects or their final thesis. Students also participate in site evaluations throughout the fieldwork experience. 

BCBA fieldwork FAQs

Do I find my own field experience practicum site?

Yes, students are responsible for securing their own placements, but our program has many local connections with various practicum sites and can support students in the greater Columbus area seeking a practicum placement. 

Can I use my field experience practicum site for research or my thesis?  

Yes, in many cases, students are able to use their practicum site for preliminary research and their final thesis or project.  

Can I complete my field experience practicum where I work?  

Yes, if your current place of employment is considered an appropriate placement, such as a school or clinic, and provides opportunities to work directly with students or clients, fieldwork can often be completed on site.  

When should I start looking for a practicum site? 

The earlier, the better. Once you’ve enrolled in a qualifying master’s program and secured a qualified BCBA supervisor, you can begin accruing fieldwork hours toward BCBA certification. Finding a practicum placement early can help you start earning hours sooner and stay on track toward meeting certification requirements. Students have up to five years to complete their required fieldwork hours. 

How many hours per week do I need to complete? 

Students must complete a minimum of 20 fieldwork hours per month and may accrue up to 160 hours per month, depending on their schedule and placement. Because requirements are based on monthly hours rather than weekly hours, students have flexibility in how they structure their fieldwork experience. Many students spread their hours throughout the month in a way that works best for their personal and professional commitments. 

Where can I learn more about fieldwork requirements?  

Certification requirements are established by the Behavior Analyst Certification Board (BACB). We recommend reviewing the Board Certified Behavior Analyst Handbook for the most current information about fieldwork, supervision, and certification requirements. 

You may also review the Master of Arts in Special Education/ABA Specialization Handbook for detailed information about the program, coursework, fieldwork, and other questions you may have about your exciting new career path.
