Becoming a licensed Applied Behavior Analyst in Washington State requires a master’s degree in an approved field, at least 1,500 hours of supervised experience, a passing score on the BCBA® exam, and a license from the Washington State Department of Health. Washington offers three licensure paths, all anchored to the BACB credentialing system. As of May 2024, counselors in this field earn a median salary of $64,220 statewide.
Washington was one of the first states to make a strong public commitment to ABA services — and not just through legislation. In 2007, the state Supreme Court ruled unanimously that private insurers could no longer exclude medically necessary mental health and autism therapy from coverage, putting ABA alongside occupational, physical, and speech therapy as a covered service. That decision changed the landscape for practitioners here. It opened up private practice opportunities, brought more salaried positions into school districts, and made ABA careers in Washington more financially viable.
If you’re thinking about becoming a Licensed Behavior Analyst (LBA) in Washington, you’re looking at a clear, well-established process. Here’s how it works.
Washington State ABA Licensing Overview
Washington enacted its ABA licensing law when Governor Jay Inslee signed Senate Bill 5488 into law in 2015. The bill added a new chapter to the Washington Administrative Code — WAC 246-805 — which took effect in July 2017. The Washington State Department of Health (DOH) oversees all licensing under this code.
The law created three license classifications:
Licensed Behavior Analyst (LBA) — The full licensure tier. Requires a master’s or doctoral degree, 1,500 hours of supervised experience, and passing the BCBA® exam. In practice, holding a current BCBA® from the BACB satisfies all requirements and is the most common path.
Licensed Assistant Behavior Analyst (LABA) — The assistant tier, aligned with the BACB’s BCaBA® credential. Requires 1,000 hours of supervised experience and 135 hours of classroom instruction, or an active BCaBA® certification.
Certified Behavior Technician (CBT) — The technician tier, equivalent to the BACB’s Registered Behavior Technician (RBT®) credential. Requires completion of an approved behavior technician training program, or an active RBT® certification from the BACB.
The Three Paths to LBA Licensure
The DOH offers three routes to LBA licensure, and all three ultimately connect back to BACB credentials:
Path 1 — For applicants pursuing, but not yet holding, a BCBA® credential. You must have a graduate degree in an approved field, documentation of 1,500 hours of supervised practice (from your graduate program and/or independent fieldwork), proof of at least 225 classroom hours in ABA coursework, and a passing BCBA® exam score submitted with your application.
Path 2 — For applicants who already hold an active BCBA®. Just provide your certificate number on the application. The DOH verifies it directly with the BACB, and that credential stands as proof of all education and experience requirements. This is the simplest and most common path.
Path 3 — For applicants who hold a current, unrestricted LBA-equivalent license from another state with substantially equivalent requirements. Washington currently recognizes 28 states for reciprocal licensure, so no additional materials are needed beyond out-of-state credential verification.
Licenses are valid for two years. Washington also issues temporary licenses to practitioners currently licensed in other states, as long as the out-of-state qualifications meet DOH standards.
Earning Your Graduate Degree
A master’s degree is the standard entry point into ABA practice, and Washington’s licensing code is somewhat more flexible than the BACB when it comes to accepted degree concentrations. While the BACB focuses primarily on behavior analysis, education, and psychology, Washington’s DOH will accept a master’s or doctorate in any of these fields:
- Behavior Analysis
- Education
- Human Services
- Engineering
- Medicine
- Natural Science
- Other fields as approved by the Department of Health
Regardless of your degree field, your graduate education must include a minimum of 225 classroom hours specific to applied behavior analysis topics. Whether those hours come through your degree program or a post-master’s certificate sequence, they’re non-negotiable for licensure.
More students are choosing accredited online programs for good reason. Online master’s degree programs in ABA let you complete coursework on your schedule, which makes it much easier to stay employed during your degree. Programs accredited by the Association for Behavior Analysis International (ABAI) or recognized through ABAI’s Tiered Model of Education carry pre-approved curricula, which makes the BACB application process smoother.
Here’s what prospective students need to know about a critical 2026 rule change: the BACB no longer accepts standalone coursework verification from unaccredited programs. Starting in 2026, all coursework must come from a BACB-recognized or ABAI-accredited program, or be attested to by a Verified Course Sequence (VCS) coordinator within your school. If you’re evaluating programs now, this makes choosing an accredited program — or one with an active VCS coordinator — more important than ever. Don’t assume your program qualifies; confirm it before you enroll.
Completing Supervised Experience
You’ll need hands-on fieldwork before you’re eligible to sit for the BCBA® exam. Washington requires at least 1,500 hours of supervised experience, which aligns with the BACB’s concentrated supervised fieldwork path.
Concentrated supervised fieldwork is more intensive than standard fieldwork. At least 10 percent of your hours must be spent in direct supervision, with a minimum of six supervisor contacts per month. Your supervisor must hold an active BCBA® or meet other BACB-specified qualifications.
The alternative is standard supervised fieldwork, which requires 2,000 hours (more total hours, but less supervisory contact). Most candidates combine both types.
You can complete your hours as part of your graduate program (through practicum placements) or independently after graduation. Either approach counts, as long as it meets BACB and DOH documentation requirements.
Passing the BCBA® Exam
Once you’ve completed your degree and fieldwork requirements, you’ll sit for the national BCBA® exam administered by Pearson VUE. The exam is 175 multiple-choice questions, covers four hours, and tests practical, professional, and ethical knowledge across the full scope of ABA practice. For a full walkthrough of the credentialing process, see our step-by-step guide to BCBA® certification.
Washington has Pearson VUE testing centers in:
- Renton
- Seattle
- Spokane
- Yakima
- Bellingham
- College Place
If you’re pursuing LABA licensure, the BCaBA® exam covers the same knowledge base at an assistant-level skill standard, with 175 questions. If you’re pursuing CBT licensure, the RBT® exam — the BACB credential that Washington’s CBT designation is built around — is 85 questions with a 90-minute window.
Passing the appropriate exam is the final step before applying for your Washington state license.
Applying for State Licensure
Applications are available from the Washington State Department of Health website, along with any supplementary forms you might need (out-of-state credential verification, supervised experience documentation, etc.).
If you hold an active BCBA®, the application is straightforward: fill in your personal information, enter your BCBA® certificate number, and submit with the $250 fee. That covers both the application and your initial license. You can apply online or through traditional paper forms.
If you don’t yet hold a BCBA®, you’ll also need to provide transcripts and supervised experience documentation showing you meet the degree and fieldwork requirements.
Fee summary by license tier:
- LBA: $250
- LABA: $160
- CBT: $95
For licensure by reciprocity, your current state’s licensing authority needs to send proof of your credentials and good standing directly to Washington’s DOH.
Applying for a Temporary License
If you’re currently licensed as an LBA in good standing in another state and either are applying for a full Washington license or will practice in Washington for fewer than 180 days, you can apply for a temporary license at a cost of $50.
Renewing Your Washington License
Washington licenses are renewed every two years on your birthday month, based on the year of original issuance. Renewal fees:
- LBA: $350
- LABA: $175
- CBT: $150
Your continuing education documentation is submitted as part of your renewal. LBAs need 32 hours of CE every two years; LABAs need 20 hours. Both require at least four of those hours in professional ethics and boundaries — requirements that mirror the BACB’s recertification standards closely.
ABA Salary and Job Outlook in Washington
Washington is one of the better-paying states for ABA and behavioral health professionals. As of May 2024, the median annual salary for substance abuse, behavioral disorder, and mental health counselors in Washington — the BLS category that includes ABA and BCBA® professionals — was $64,220. That’s meaningfully higher than the national median of $59,190. For a broader look at how Washington compares with other states, see our ABA salary data by state.
It’s worth noting that BLS data covers a broad range of job titles within this occupational category. BCBA®-certified professionals, particularly those in supervisory roles, clinical director positions, or private practice, typically earn above the published median figures.

| National | $59,190 | $98,210 |
The Seattle metro’s 90th-percentile earners top $103,000 — a figure typically associated with experienced LBAs in clinical leadership or private practice settings.
Job Outlook
Nationally, employment in this field is projected to grow 17% from 2024 to 2034, adding roughly 81,000 new positions and generating approximately 48,300 average annual openings. Washington’s strong autism insurance mandate and continued growth in ASD diagnoses among school-age children have driven steady demand for qualified practitioners throughout the state, particularly in the Puget Sound region and the eastern Washington corridor.
Washington ABA Providers and Professional Organizations
The Washington Association for Behavior Analysis (WABA) was the driving force behind Senate Bill 5488, and the organization continues to be the primary professional home for ABA practitioners in the state. WABA is an affiliate of both ABAI and APBA, and it offers:
- Access to ABAI job listings
- Annual conferences
- Continuing education opportunities
- Student membership at a reduced rate
Staying connected to WABA is one of the most practical things you can do to keep up with changes to state licensing rules, CE requirements, and professional standards. Their members were the first to know about the rulemaking details as WAC 246-805 was being implemented, and that kind of early access to information matters when your license is on the line. If you’re also considering practice in other states, our state-by-state guide to ABA licensing requirements covers all 50 states.
Frequently Asked Questions
What are the three ABA license types in Washington State?
Washington licenses three tiers of ABA professionals: the Licensed Behavior Analyst (LBA), the Licensed Assistant Behavior Analyst (LABA), and the Certified Behavior Technician (CBT). Each tier corresponds to a BACB credential — the BCBA® for LBAs, the BCaBA® for LABAs, and the RBT® for CBTs. Requirements scale with each level, from the full master’s degree and supervised fieldwork required for LBAs down to the technician training program required for CBTs.
Do I need a BCBA® to get licensed as an LBA in Washington?
Not technically — you can meet the requirements without holding a current BCBA® by documenting your degree, fieldwork hours, and passing exam score separately. That said, earning the BCBA® first is the most efficient path. It satisfies all LBA requirements in a single credential and is what most employers expect, regardless of state licensing status.
How long does it take to become a licensed LBA in Washington?
Most candidates spend two to three years on a master’s program, followed by 1,500 hours of supervised fieldwork (which can overlap with graduate school practicum placements). Once you’ve passed the BCBA® exam, the DOH application is typically processed within a few weeks. You’re looking at roughly two to four years total from starting your graduate program to holding your license.
What does an ABA professional earn in the Seattle area?
According to May 2024 BLS data, the median annual salary in the Seattle-Tacoma-Bellevue metro is $65,290, with the top 10% earning $103,210 or more. BCBA®-certified professionals in supervisory or private practice roles frequently earn above the published median figures.
Can I transfer my ABA license from another state to Washington?
Yes. Washington recognizes 28 states for reciprocal licensure. If your current license is from one of those states and remains in good standing, you can apply by endorsement without submitting additional materials. Your current state’s licensing authority will need to send credential verification directly to the Washington DOH.
