Key Credentials for ABA Providers in Washington State
Board Certified Behavior Analyst (BCBA) Certification
The Behavior Analyst Certification Board (BACB) awards BCBA certification after rigorous training, supervised experience, and passing a national exam. A BCBA is the lead clinician who designs and oversees ABA programs. You can verify any BCBA's status using the BACB's online registry. Look for the certificant's name, certification number, and expiration date. Make sure the certification is current and not subject to any disciplinary actions.
Washington State License for Behavior Analysts
Washington requires all behavior analysts to be licensed through the Washington State Department of Health (DOH). This license (often called an LBA) ensures the provider has met state-specific requirements, including background checks and continuing education. Use the DOH's Provider Credential Search tool to look up a license by name or number. Confirm the license is active and note any restrictions or disciplinary history.
Registered Behavior Technician (RBT) Certification (for Direct Staff)
Many ABA sessions are delivered by RBTs who work under BCBA supervision. While the BCBA holds primary responsibility, every RBT should be certified through the BACB. Check RBT credentials on the BACB site as well. In Washington, RBTs do not require a separate state license, but the BACB certification is essential.
Malpractice Insurance
Reputable providers carry professional liability insurance. Ask for proof of coverage, including policy limits and effective dates. This protects both the provider and your family in the rare event of an error or omission.
Continuing Education Units (CEUs)
BCBAs must earn CEUs to maintain certification. Ask a provider about their recent CEU topics-evidence of training in ethics, cultural competence, or new ABA techniques is a good sign of dedication to quality care.
Step-by-Step: How to Verify an ABA Provider's Credentials
Step 1: Gather the Provider's Full Name and Credentials
Start by asking the clinic for the full name (including middle initial if needed) and certification/license numbers for the supervising BCBA and any other key staff. Many clinics list this on their website or in an intake packet.
Step 2: Use the Washington State Department of Health License Lookup
Visit the DOH's License Lookup page. Choose "Behavior Analyst" from the profession list and enter the name. Review the license status, issue date, and expiration. If the license shows a status other than "Active" or has a disciplinary notation, proceed with caution or consider another provider.
Step 3: Confirm BCBA Certification through the BACB Registry
Go to the BACB website and use the Certificant Registry. Enter the certificant's name or certification number. The result will show the certification type, number, initial certification date, expiration date, and any disciplinary actions. A current certification with no sanctions is what you want.
Step 4: Check RBT Certifications for Direct Staff
For RBTs, use the same BACB registry but select "Registered Behavior Technician" as the credential type. While you may not have the names of every RBT, the BCBA should be able to confirm that all supervising staff hold valid RBT certifications.
Step 5: Verify Insurance Panel Participation
Divide into two groups: private insurance and public insurance.
- Private Insurance: Call your insurance company or check their online portal to see if the provider is in-network. If they are out-of-network, ask about reimbursement rates and prior authorization requirements.
- Medicaid (Apple Health): Washington's Apple Health program covers ABA therapy for eligible children. Contact your Apple Health managed care plan (e.g., Coordinated Care, Molina, Community Health Plan of Washington) to confirm the provider is enrolled as a Medicaid provider.
Important: Even if a provider is licensed and certified, they must be paneled with your specific insurance plan. If they are not, you may face higher out-of-pocket costs or denial of coverage.
Step 6: Ask for a Written Credentials Summary
Request a document that includes the provider's license number, BCBA certification number, expiration dates, and malpractice insurance information. A ethical provider will provide this freely. Keep a copy for your records.

Common Mistakes to Avoid When Verifying ABA Credentials
- Skipping the license check for the supervising BCBA. Even if a clinic is well-known, individual licenses expire. Always check.
- Assuming all staff with "BCBA" in their title are certified. Some individuals may use the term "behavior analyst" without being certified. Look for the explicit BCBA credential.
- Overlooking disciplinary records. A provider may have an active license but still have a history of complaints. Always check the DOH site for any formal actions.
- Not verifying insurance participation before starting. You might find a great provider, only to learn they don't accept your plan, leading to delays or denials.
- Ignoring supervision ratios. Washington state regulations require BCBAs to supervise RBTs appropriately. Ask what the supervision ratio is and how often the BCBA meets with the RBT and observes sessions.
