1. Methodology: How We Built This Dataset
This report draws from ESBAP's provider database, built through systematic enrichment of public data sources. No provider paid to be included or excluded. The data reflects what is publicly available about each organization.
| Data Source | What It Provides | Coverage |
|---|---|---|
| CMS NPI Registry | Organization names, authorized officials, addresses, taxonomy codes | 2,678 orgs matched (31%) |
| Google Places API | Ratings, review counts, business status, contact info | 8,405 orgs (98%) |
| BHCOE Directory | Organizational accreditation status | 376 accredited |
| CASP Directory | Organizational membership and verification | 330 verified |
| OIG LEIE | Federal exclusion from healthcare programs | 8,553 checked (100%) |
| State SOS Filings | Business entity type, registered agents, incorporation data | 1,912 structures identified |
| Census Geocoder | Location coordinates for mapping | 12,083 of 12,250 locations (98.6%) |
Note on Limitations
This dataset captures organizations that maintain an NPI registration or a detectable web presence. Solo practitioners, very small practices operating without an NPI, and organizations using only trade names not matched to legal names may not be represented. We estimate this covers 85-90% of the organized ABA provider market.
2. The ABA Provider Environment
The ABA therapy market in the United States has grown into a $4 to $5 billion industry, driven by rising autism diagnosis rates (now 1 in 36 children per CDC data), insurance mandates in all 50 states, and expanding Medicaid coverage. This growth has attracted significant investment and created a fragmented field of providers ranging from solo BCBA practices to multi-state chains with hundreds of locations.
The typical ABA provider organization operates from a single location. But the distribution is heavily skewed: the largest organizations operate across 50 or more locations, meaning a relatively small number of companies serve a disproportionate share of families.
3. Ownership: Who Controls ABA?
Of the 8,553 organizations in our database, we have identified ownership type for only 994 (11.6%). The remaining 7,559 have an unknown ownership structure. This opacity is itself a finding: most ABA organizations do not publicly disclose who owns them.
Among those with identifiable ownership:
- 847 organizations (9.9%) show PE-backed ownership indicators. These include organizations matched to known PE-backed platforms (Centria Healthcare, Action Behavior Centers, Hopebridge, and others) as well as organizations whose Secretary of State filings reveal PE-associated registered agents.
- Business structure data was identified for 1,912 organizations (22%), with LLC being the most common structure, followed by professional corporations and PLLCs.
The Opacity Problem
88% of ABA organizations have an unknown ownership type. For families, this means there is no easy way to know whether the organization providing your child's therapy is owned by a clinician, a corporation, or an investment fund. ESBAP exists to close this gap. When organizations claim their profile and verify their ownership, families can make informed decisions.
4. The Accreditation Gap
Organizational accreditation is the strongest available signal of commitment to quality standards. BHCOE (Behavioral Health Center of Excellence) and CASP (Council of Autism Service Providers) are the two primary accreditation bodies for ABA organizations.
In January 2026, CASP acquired BHCOE and its parent company Jade Health, creating a single dominant accreditation authority. This consolidation may accelerate accreditation adoption, but today the numbers are stark: 92.6% of ABA providers operate without any independent organizational quality verification.
To be clear: absence of accreditation does not mean absence of quality. Accreditation is voluntary, costly, and time-consuming. Many excellent providers have not pursued it. But accreditation does represent a verifiable, third-party assessment of organizational practices, and its near-absence across the industry means families have very little objective quality data to work with.
5. Clinical Leadership: The Missing Data
The clinical director is the most important person in an ABA organization. They set supervision standards, determine treatment protocols, hire and train staff, and make the clinical decisions that directly affect outcomes. Knowing who this person is, and whether they hold a BCBA credential, is fundamental to evaluating a provider.
ESBAP has identified clinical directors for 2,833 organizations (33.1%). For the remaining two-thirds, the clinical leadership is either not publicly identifiable or the organization does not have a designated clinical director.
This finding has two implications:
- For families: If you cannot find out who the clinical director is at your provider, ask directly. If the answer is vague, or if the person named does not hold a BCBA credential, consider this a significant concern.
- For the industry: Clinical leadership should be public information. The person responsible for treatment quality should be identifiable, contactable, and accountable. Opacity in clinical leadership is not a neutral condition.
6. What Families Are Saying
ESBAP indexed 217,250 public Google reviews across 8,405 ABA provider organizations. The average rating is 4.3 out of 5.0.
This number requires context. A 4.3 average is typical for healthcare service providers on Google. It tells us that most families rate their experience positively based on the factors Google reviews capture: scheduling convenience, staff friendliness, facility quality, and responsiveness.
What Google reviews do not capture are the factors that matter most for ABA quality: supervision ratios, treatment fidelity, data-driven decision making, billing accuracy, and clinical outcomes. A provider can have a 5.0 Google rating while maintaining dangerously high caseloads.
This is precisely why ESBAP built the 7 Key Ethics Indicators (KEI) framework. The KEI system asks employees and families to rate providers on the dimensions that actually determine care quality: supervision, training, compensation, management ethics, work-life balance, client outcomes, and billing transparency.
Google Ratings Are Not Quality Ratings
A high Google rating means families had a positive customer experience. It does not mean the organization provides clinically excellent or ethically sound ABA therapy. The two can coexist, but they are not the same measurement. ESBAP's KEI ratings fill this gap by measuring what Google cannot.
7. What This Means
This data paints a picture of an industry that has grown faster than its accountability structures. ABA therapy works. The evidence base is strong. But the organizations delivering this therapy operate in an environment where:
- 88% have no publicly identifiable ownership type
- 93% operate without organizational accreditation
- 67% have no identifiable clinical director
- The primary public quality signal (Google ratings) measures customer experience, not clinical quality
- No independent, comprehensive ethics rating system existed until ESBAP
None of this means most providers are unethical. Our experience suggests the opposite: the majority of people working in ABA are deeply committed to the children they serve. But structural accountability matters. When investment firms can acquire clinical organizations without public disclosure, when 93% of providers operate without third-party quality verification, and when families have no reliable way to compare providers on ethics, the conditions exist for quality to erode.
ESBAP was built to change this. Not by punishing anyone, but by making information available that should have always been available. When ownership is transparent, when accreditation is visible, when clinical leadership is identifiable, and when employees and families can share their experiences, the market works better. Good providers are rewarded. Questionable practices become visible. And families can make decisions based on evidence rather than marketing.

If you lead an ABA organization and you believe in what you do, make it visible:
- Claim your organization on ESBAP. Verify your ownership, identify your clinical director, and show families that you stand behind your practices. Claim your organization here.
- Pursue accreditation. BHCOE and CASP accreditation are the strongest available signals of organizational quality. If you cannot pursue accreditation yet, explain why on your profile.
- Publish your supervision ratios. If your ratios are strong, say so publicly. If they are not, improve them.
- Welcome reviews. Invite your employees and families to rate you on ESBAP's KEI framework. Good organizations have nothing to fear from transparency.
The organizations that will win in this industry are the ones that can prove their quality, not just claim it.
