When you choose an ABA provider for your child, you are making one of the most consequential decisions of their developmental journey. The quality of that provider will shape your child's progress, your family's experience, and the trajectory of years of therapy. But how do you know whether a provider meets real quality standards?

Individual credentials matter. A Board Certified Behavior Analyst (BCBA) has passed a certification exam and completed supervised fieldwork. But individual certification tells you about one person. It tells you nothing about the organization that person works for: its supervision practices, staff turnover, billing transparency, or commitment to ethical care.

That is where organizational accreditation comes in. And that is where the numbers get concerning.

The Accreditation Gap in ABA

ESBAP tracks 8,553 ABA provider organizations across the United States. Of those, only 632 (7.4%) hold accreditation from either BHCOE or CASP, the two primary organizational accreditation bodies in applied behavior analysis. That means 92.6% of ABA providers operate without any independent, third-party verification of their organizational quality.

To be clear: lack of accreditation does not automatically mean poor quality. Many excellent, small practices choose not to pursue accreditation because of the cost and administrative burden. But accreditation does mean that an organization has voluntarily submitted itself to external review, met defined standards, and committed to maintaining them. That distinction matters when you are trusting a provider with your child's care.

What Is BHCOE Accreditation?

BHCOE (Behavioral Health Center of Excellence) was founded in 2015 to create an accreditation framework specifically for ABA providers. Unlike general healthcare accreditations, BHCOE was built from the ground up for behavior analysis organizations.

BHCOE accreditation evaluates providers across several measurable domains:

BHCOE offers tiered accreditation levels based on how well an organization scores across these domains. Currently, 376 ABA organizations hold BHCOE accreditation.

What Is CASP Accreditation?

CASP (Council of Autism Service Providers) takes a different approach. Founded as a membership and standards organization, CASP focuses on organizational governance and policy frameworks rather than individual outcome metrics.

CASP accreditation evaluates:

CASP has 330 verified member organizations. Its accreditation process involves a self-study, document review, and site visit component.

BHCOE vs. CASP: How They Compare

Dimension BHCOE CASP
Primary focus Measurable outcomes and satisfaction data Organizational standards and governance
Accredited organizations 376 330
Evaluation method Surveys, KPI benchmarking, outcome data review Self-study, document review, site visits
Staff perspective Employee satisfaction surveys included Credentialing and supervision policy review
Client perspective Direct family satisfaction surveys Service delivery standards and family involvement policies
Tiered levels Yes (based on performance scores) No (pass/fail model)
Founded 2015 2009

Both accreditations signal that a provider has gone beyond the minimum requirements of state licensure and individual BACB certification. They indicate organizational intent to operate transparently and be held accountable by an external body.

The CASP-BHCOE Acquisition: What Changed in January 2026

In January 2026, CASP acquired BHCOE. This brought the two primary ABA accreditation bodies under a single organizational umbrella. The implications of this acquisition are still unfolding, but several questions are worth tracking:

Why this matters

With only 7.4% of ABA providers accredited, the field needs accreditation to become more accessible, not less. ESBAP will continue tracking both BHCOE and CASP accreditation status independently in our provider directory as the two organizations determine their path forward.

International Accreditation Gaps: The BACB Departure

Accreditation matters even more in the context of broader changes to professional credentialing. In January 2026, the Behavior Analyst Certification Board (BACB) stopped certifying practitioners in the United Kingdom. Australia will follow in January 2027.

The BACB's departure from these markets creates a significant gap. Without BACB certification, international ABA practitioners lose access to the most widely recognized individual credential in the field. This puts additional pressure on organizational accreditation to fill the quality assurance role.

However, BHCOE and CASP are currently focused on the US market. International ABA providers may soon face a situation where neither individual certification nor organizational accreditation is available through established bodies. For families seeking ABA services in the UK, Australia, or other international markets, verifying provider quality will become considerably more difficult.

International families

If you are seeking ABA services outside the United States, ask your provider directly about their quality assurance practices, staff supervision structure, and whether they voluntarily submit to any external review process. The absence of formal accreditation options makes your own due diligence even more important.

What to Ask Your Provider About Accreditation

Whether you are choosing a new ABA provider or evaluating your current one, accreditation status is a data point worth understanding. Here are specific questions to ask:

  1. "Are you BHCOE or CASP accredited?" If yes, ask which level and when their accreditation was last renewed. If no, ask why not.
  2. "What are your BCBA-to-client supervision ratios?" Accredited organizations typically maintain lower ratios, but ask for the specific number.
  3. "What is your annual staff turnover rate?" BHCOE tracks this metric. Providers who know the answer are more likely to be managing it actively.
  4. "Can I see client outcome data?" Accredited providers are expected to track and report treatment progress. A provider that cannot show you aggregate outcome trends may not be measuring them.
  5. "How do you handle billing disputes or complaints?" Accreditation standards require formal complaint resolution procedures. Ask whether these exist and how they work.

A provider that answers these questions openly and with specific data is demonstrating the transparency that accreditation is designed to encourage, whether or not they hold the credential.

Accreditation Is Not Enough on Its Own

Accreditation is one of several indicators that ESBAP tracks for every ABA provider in the country. It is an important signal, but it should be considered alongside other factors: ownership structure, clinical leadership, staff stability, client reviews, and billing practices.

An accredited provider with a private equity owner and high staff turnover may not deliver better care than an unaccredited, BCBA-owned practice with stable staff and strong parent training. Context matters. That is why ESBAP built a directory that shows all of these factors together, so families and clinicians can make informed decisions based on the full picture.

For behavior analysts considering where to work, accreditation status is also worth investigating. Organizations that pursue accreditation tend to invest more in staff development, maintain reasonable caseloads, and create cultures where clinical judgment is respected. ESBAP's resources for BCBAs include guidance on evaluating potential employers.

What ESBAP Is Doing

ESBAP tracks accreditation data for every ABA provider organization we can identify. We pull from BHCOE and CASP directories, cross-reference with state licensing records, and update our database continuously. When you search for a provider in our directory, you see their accreditation status alongside ownership type, clinical director information, Google reviews, and community ethics ratings.

We believe accreditation should be one part of a larger quality picture. Our 2026 State of Ethics in ABA report provides a full analysis of quality indicators across the industry. And if you are a provider, you can claim your organization on ESBAP to verify your information and demonstrate your commitment to transparency.

The 7.4% accreditation rate tells us that voluntary quality standards alone are not enough to protect families. Until accreditation becomes the norm rather than the exception, independent platforms like ESBAP exist to fill the information gap.

Frequently Asked Questions

What is BHCOE accreditation?

BHCOE (Behavioral Health Center of Excellence) accreditation is a voluntary quality credential for ABA provider organizations. It evaluates clinical outcomes, staff satisfaction, client satisfaction, and operational practices. As of 2026, 376 ABA organizations hold BHCOE accreditation. In January 2026, CASP acquired BHCOE, bringing both accreditation bodies under one organization.

What is CASP accreditation?

CASP (Council of Autism Service Providers) is a membership and accreditation organization for ABA providers. It focuses on organizational standards including clinical governance, staff qualifications, ethical practices, and service delivery quality. CASP has 330 verified member organizations. In January 2026, CASP acquired BHCOE.

What percentage of ABA providers are accredited?

Only 7.4% of ABA providers hold organizational accreditation. Out of 8,553 providers tracked by ESBAP, 632 hold either BHCOE accreditation (376 organizations) or CASP accreditation (330 organizations). The remaining 92.6% operate without any independent organizational quality verification.

What is the difference between BHCOE and CASP accreditation?

BHCOE emphasizes measurable outcomes: client progress data, staff turnover rates, satisfaction surveys, and clinical KPIs. CASP focuses on organizational standards: governance structure, clinical oversight policies, staff credentialing, and ethical guidelines. Both evaluate service quality but through different lenses. Since CASP acquired BHCOE in January 2026, the two frameworks may eventually merge.

Does accreditation guarantee quality ABA services?

Accreditation is a strong quality signal, but it is not a guarantee. It confirms that an organization met defined standards at the time of evaluation. Families should also evaluate supervision ratios, staff stability, billing transparency, and treatment outcomes. ESBAP's directory includes accreditation status alongside six other ethics indicators for a complete picture.

Why are so few ABA providers accredited?

Accreditation is voluntary. No state or federal requirement exists for ABA organizations to hold BHCOE or CASP accreditation to operate and bill for services. The process requires time, financial investment, and willingness to submit to external review. Many smaller practices view it as cost-prohibitive. Some larger organizations avoid the transparency requirements.

How can I check if my ABA provider is accredited?

Search for your provider on the ESBAP directory at esbap.org/directory.html. ESBAP tracks BHCOE and CASP accreditation status for all 8,553 ABA provider organizations. You can also check the BHCOE and CASP directories directly, but ESBAP consolidates both into a single searchable database alongside ownership data, clinical leadership, and ethics ratings.

What does the BACB departure from international markets mean for accreditation?

The BACB stopped certifying practitioners in the United Kingdom (January 2026) and will stop in Australia (January 2027). These departures leave gaps in professional credentialing that organizational accreditation bodies like BHCOE and CASP could partially fill. However, both are currently US-focused, meaning international ABA markets may lack both individual and organizational quality standards.
