How to Become a BCBA or ABA Therapist

The field of Applied Behavior Analysis (ABA) has become one of the most influential within contemporary psychology and education. Today, two of the most prominent roles in this discipline are the ABA therapist and the Board Certified Behavior Analyst (BCBA). Although both share the mission of promoting positive behavioral change, their responsibilities, training levels, and professional scopes differ.

This section explores in depth what each role entails, how to train for it, what professional pathways exist, and what opportunities are available.

What Is an ABA Therapist?

An ABA therapist is responsible for implementing behavioral modification strategies that reduce challenging behaviors and teach alternative, communicative, social, or academic skills.

ABA therapists primarily work with children and adolescents with Autism Spectrum Disorder (ASD), although they may also intervene in other contexts where behavioral or learning difficulties exist. During sessions, they record data, apply reinforcement, model behaviors, and work closely with families to ensure treatment consistency.

Unlike the BCBA, the ABA therapist does not design or evaluate intervention programs but rather implements and adjusts them under supervision. Many ABA therapists begin their careers in this role before advancing toward higher certifications.

How to Become an ABA Therapist

Becoming an ABA therapist is an excellent entry point into the field of behavior analysis. It requires basic education, hands-on training, and ongoing supervision. It is an ideal profession for those who enjoy direct work with people and seek to make a tangible impact in their daily lives.

The process combines academic education, practical training, and professional certification. Although some employers accept staff with minimal education and on-the-job training, obtaining RBT and BCBA certification significantly broadens career opportunities and professional credibility.

Steps to Become an ABA Therapist

Obtain a Bachelor’s Degree or Related Education
While a university degree is not required to work as a behavioral technician, holding a bachelor’s degree in psychology, education, child development, or social work provides a solid foundation in learning, human development, and behavioral principles.
Complete ABA Training and RBT Certification
The next step is to complete the 40-hour ABA training course approved by the Behavior Analyst Certification Board (BACB). This training covers behavioral principles, reinforcement, professional ethics, family collaboration, and legal aspects. After completing it, candidates must pass the RBT competency assessment supervised by a BCBA.
Gain Supervised Practical Experience
Supervised practice is key to applying theory in real contexts. Trainee therapists work directly with children or adults under the guidance of a certified supervisor. This experience strengthens observation skills, data collection, and clinical decision-making.
Engage in Continuing Education
ABA is a dynamic and constantly evolving field. Therefore, ABA therapists must stay up to date with the latest research, techniques, and resources. Continuing education ensures more effective interventions and sustained professional growth.
Advance to Higher Studies (Optional)
Some ABA therapists choose to continue their education by pursuing a master’s or doctoral degree in Applied Behavior Analysis, which allows them to later obtain BCBA certification and work independently or in supervisory roles.

Career Paths, Opportunities, and Work Settings in ABA

Working as an ABA therapist opens multiple avenues for career growth. Among the most common are:

Clinical or In-Home ABA Therapist: Works directly with clients, implementing programs designed by a BCBA.
ABA Specialist in School Settings: Collaborates with teachers to improve students’ behavior and academic performance.
ABA Program Coordinator: Manages the implementation of services in therapeutic or educational centers.
Independent Practitioner or Contractor: Experienced professionals may work autonomously, providing ABA services in coordination with supervising BCBAs.

Work environments include private clinics, public and private schools, pediatric hospitals, early intervention programs, and nonprofit organizations. In all cases, collaboration with families and interdisciplinary teams is central.

Demand and Average Salary for ABA Therapists

The demand for ABA therapists has grown exponentially in the past decade. Between 2010 and 2023, job postings in the U.S. increased from 789 to over 65,000, reflecting the expansion of ABA services in educational, clinical, and community contexts.

The average salary for an ABA therapist is around $44,600 per year (approximately $21 per hour). Salaries vary based on experience, employer type, and geographic location. In metropolitan areas or states with high demand, such as California, Massachusetts, or Texas, salaries can exceed $50,000 per year.

Furthermore, those who continue training toward BCBA certification often gain access to supervisory positions and significant salary increases.

What Is a BCBA Therapist?

A BCBA (Board Certified Behavior Analyst) is a board-certified behavior analyst specialized in designing, implementing, and supervising evidence-based behavioral intervention programs.

Unlike the ABA therapist, the BCBA not only applies strategies but also evaluates, plans, and oversees the entire therapeutic process. These professionals hold a master’s or doctoral degree in behavior analysis or a related field and complete extensive supervised training before earning official certification from the Behavior Analyst Certification Board (BACB).

The BCBA works directly with clients but also leads intervention teams, trains ABA therapists, and ensures that all practices meet ethical and professional standards. Their role is essential for guaranteeing service quality and intervention effectiveness.

How to Become a BCBA Therapist

Becoming a BCBA requires a deeper academic and professional commitment. This certification is ideal for individuals seeking leadership, supervisory, or clinical director roles, as well as independent practice.

Requirements include postgraduate education, supervised experience, and passing a comprehensive exam administered by the BACB.

Steps to Become a BCBA

Obtain a Bachelor’s Degree
The process begins—just as with becoming an ABA therapist—with a university degree in psychology, education, human development, or behavioral sciences. This foundation is essential for entering advanced studies.
Complete a Master’s Degree with a Verified Course Sequence (VCS)
Candidates must complete a master’s degree in Applied Behavior Analysis or a related field that includes a Verified Course Sequence (VCS) approved by the Association for Behavior Analysis International (ABAI). This sequence ensures that the coursework meets the academic standards required to sit for the BCBA exam.
Complete Supervised Practice
Between 1,500 and 2,000 hours of supervised experience must be completed (depending on the type of practice). During this period, candidates work with real clients under the guidance of a BCBA, learning to design programs, conduct functional assessments, and apply behavioral principles in complex situations.
Pass the BCBA Exam
The exam consists of 185 questions and assesses knowledge in behavior measurement, intervention procedures, ethics, and supervision. It lasts four hours and is considered one of the most rigorous exams in the psychological and educational fields.
Obtain a State License
Some states require an additional license to practice as a BCBA. This process typically involves submitting academic credentials, BACB certification, and compliance with local regulations.

Career Paths, Opportunities, and Work Settings for BCBAs

The BCBA role offers a broad range of professional opportunities with growth potential across multiple areas:

Behavioral Consultant: Advises schools, clinics, and organizations on effective intervention design.
ABA Program Supervisor: Ensures the quality and fidelity of therapeutic implementation.
Clinical or ABA Center Director: Leads teams of therapists and analysts, overseeing comprehensive client care.
Researcher or University Instructor: Many BCBAs pursue applied research or academic teaching in behavior analysis.
Private Practice: Some professionals work independently, providing assessment, program design, and remote supervision services.

Work settings include autism centers, hospitals, educational institutions, universities, early intervention programs, and mental health organizations.
BCBAs may also develop programs for adults in workplace or residential environments, extending the impact of ABA beyond childhood applications.

Demand and Average Salary for BCBAs

The demand for BCBAs has steadily increased in the United States and in other countries adopting BACB standards. This growth is driven by the expansion of autism services, the recognition of ABA as an evidence-based treatment, and the requirement for certified supervision in therapeutic settings.

The average annual salary for a BCBA ranges from $65,000 to $90,000, and can exceed $100,000 in clinical director or private practice roles. In states such as California, New York, and Massachusetts, where the cost of living is higher, salaries are also greater.

Beyond salary, many positions include additional benefits such as continuing education, paid supervision, and professional development programs. Job stability and projected growth make this career one of the most promising within the behavioral sciences.

Frequently Asked Questions

Why is BACB certification important?
Certification from the Behavior Analyst Certification Board (BACB) verifies that a professional has mastered the principles of ABA and possesses the ethical and technical competencies required to apply them rigorously. The BCBA credential, the most sought-after, requires specific academic training and supervised experience, serving as an internationally recognized mark of quality and a requirement for most employers in the field. It also establishes a consistent practice standard that helps protect clients and families.
How long does it take to become a BCBA?
The full path usually takes between 6 and 8 years: approximately four years for a bachelor’s degree, two to three years for a master’s degree, and the supervised fieldwork period. It is highly recommended to complete much of the supervised experience during graduate studies so that academic and practical training develop in tandem.
How difficult is the BCBA exam?
The BCBA exam is comprehensive and highly specialized, assessing knowledge of ABA principles, ethical considerations, and their practical application. Effective preparation combines structured review of coursework, multiple mock exams, and targeted study materials. Its rigor means that many candidates pass after more than one attempt, underscoring the importance of time management and consistent preparation.
Can you practice ABA without being a BCBA?
Yes, but only under the supervision of a BCBA. For example, Registered Behavior Technicians (RBTs) implement behavior plans and collect data, but they cannot independently evaluate, design, or modify interventions. Without BCBA certification, professionals may face limitations in their scope of practice, employment opportunities, and earning potential.
How do you maintain BCBA certification?
Certification must be renewed every two years by completing continuing education requirements and adhering to BACB ethical guidelines. A renewal application must be submitted before the certification expires. Failure to meet these requirements may result in suspension or loss of credentials.
What skills stand out in successful ABA and BCBA professionals?
Accurate observation, empathy, and effective communication are essential. BCBA professionals also demonstrate strong data analysis skills, the ability to design and evaluate interventions, and a commitment to ethical standards throughout all stages of behavioral work.
What role does supervised fieldwork play in certification?
Supervised fieldwork is a cornerstone of BCBA certification. The BACB requires a set number of supervised hours (typically around 1,500) before candidates can take the exam. During this experience, trainees conduct behavioral assessments, design and implement interventions, collaborate with clients and caregivers, and apply ethical principles in real-world contexts. This ensures that professionals are well-prepared to handle practical challenges upon certification.
How do ABA and BCBA differ in terms of evaluation and intervention?
BA focuses on the direct implementation of behavior modification techniques to address specific goals. BCBA professionals, in contrast, take a broader role, conducting assessments, designing individualized behavior plans, setting data collection procedures, supervising implementation, and ensuring ethical compliance throughout the process. In short, BCBAs design, oversee, and evaluate, while day-to-day implementation is typically carried out by supervised staff such as RBTs.
