To become a licensed behavior analyst in Illinois, you’ll need a master’s degree in behavior analysis or a related field, 1,500–2,000 hours of supervised fieldwork, and a passing score on the BCBA® exam. From there, you apply for a Licensed Behavior Analyst (LBA) credential through IDFPR. The process typically takes 2–3 years.
Illinois is among the most recent states to introduce a formal licensing requirement for Applied Behavior Analysts. Taking effect in 2025, both behavior analysts and assistant behavior analysts working in the Land of Lincoln need to be licensed by the Illinois Department of Financial and Professional Regulation (IDFPR).
The license requirements follow the Behavior Analyst Certification Board (BACB) Model Act, a proposed blueprint for state-level ABA legislation that establishes minimum education and training qualifications and provides for state oversight of the field. Right in line with that model, holding a BCBA® (or BCaBA® for assistant ABAs) meets the Illinois state licensing requirements.
Step 1. Earn a Master’s Degree in Behavior Analysis or a Related Field
If you’re coming to ABA practice fresh, you’ll need to start with the right education to qualify for a BCBA®. That means a master’s degree, and ideally one accredited by the Association of Professional Behavior Analysts (APBA) or recognized by the Association for Behavior Analysis International (ABAI).
Degrees in psychology, behavior analysis, or education that meet BACB’s coursework requirements in both content and quantity will put you in good shape. Fully accredited programs are still relatively rare, but BACB will also accept other master’s graduates who have the right coursework behind them. That coursework can qualify through attestation by a VCS (Verified Course Sequence) Coordinator. Keep in mind that the course-by-course review option under VCS was no longer available after 2025, so all approvals must now go through attestation.
The process for BCaBA® candidates is similar, but they need only a bachelor’s degree to get started.
Step 2. Complete a Period of Supervised Practice
Hands-on experience is a real requirement in behavior analysis, not just a formality. There’s a wide range of variation across individual clients and cases, and you won’t find everything you need to know in a textbook.
BACB, and by extension Illinois, requires you to complete a period of direct, practical treatment under the careful supervision of someone already approved to perform ABA therapy. If you want a deeper look at what supervised fieldwork requirements actually look like day-to-day, we’ve broken that down in detail. There are two accepted types of supervised experience:
Supervised Fieldwork: 2,000 hours with 4 supervisor contacts per month and 5 percent of total hours supervised.
Concentrated Supervised Fieldwork: 1,500 hours with 6 supervisor contacts per month and 10 percent of total hours supervised.
You can also combine both methods depending on your supervisor’s availability and caseload, which means your total supervised hours could fall anywhere between 1,500 and 2,000.
Step 3. Pass the BCBA® Certification Exam
With your experience accumulated, you’re one big step from certification. The BCBA® or BCaBA® Certification Exam is 175 multiple-choice questions you’ll need to answer in four hours. It covers 9 core content areas:
- Behaviorism and Philosophical Foundations
- Concepts and Principles
- Measurement, Data Display, and Interpretation
- Experimental Design
- Ethical and Professional Issues
- Behavioral Assessment
- Behavior-Change Procedures
- Selecting and Implementing Interventions
- Personnel Supervision and Management
These cover the essential elements on the BCBA® task list. A solid review of your coursework notes and supervised fieldwork experience should give you what you need to get through the test. The BCaBA® exam covers similar territory at a less advanced level.
Both exams are available only through Pearson VUE, which has testing centers around the state. You’ll need to register with BACB for approval to sit the exam before scheduling it with Pearson.

Step 4. Apply for Licensure With the Illinois Department of Financial and Professional Regulation
Official licensing for behavior analysts in Illinois got underway in 2025, and all applications go through IDFPR’s CORE system online. The official titles for the new licenses are Licensed Behavior Analyst (LBA) and Licensed Assistant Behavior Analyst (LABA).
Through the system, you’ll need to separately provide certification of your education, proof of passing the BCBA® Certification Exam, and a current, valid BCBA® Certification.
The initial application fee is $400 for an LBA and $100 for a LABA. You’ll also need to arrange fingerprinting and a background check, similar to requirements in other states.
One important note: the LBA/LABA license is separate from the provider registration required by IDHS before you can bill for behavior intervention services under the state’s Medicaid Waivers Act. If you plan to offer and bill for those services, you’ll need to register with that system separately.
Getting Your License by Endorsement
If you already hold an out-of-state ABA license with equivalent standards, you can receive licensure by endorsement in Illinois. In practice, that typically means holding a license from another state that also requires BCBA® certification. You’ll need to submit a certification of current licensure along with an official transcript and diploma, plus proof of passage of the BCBA® exam or an equivalent. Your existing license must be active and in good standing.
Maintaining Your LBA License
Licenses renew on a two-year cycle. The renewal fee is $300 for LBAs and $75 for LABAs. You’ll also need 30 CEUs in continuing education (20 for LABAs). Accepted CE must come from an approved sponsor, which includes BACB-approved CE providers, the American Psychological Association, Illinois colleges or universities offering degrees in behavior analysis, and other approved providers.
Special Education and Insurance: Illinois Has Required BCBA® Credentials for Years
While the overall LBA/LABA licensing framework is new, Illinois behavior analysts are no strangers to credential requirements. Since 2007, Illinois Public Act 094-0948 has defined a behavior analyst in the context of special education as someone holding a BCBA®, meaning ABAs without board certification haven’t been able to work in Illinois schools for quite some time. The Illinois Department of Human Services has also required BCBA® certification for approval as a provider for behavior intervention services with the Division of Developmental Disabilities.
It’s pretty likely that many practicing ABAs in Illinois already hold their BCBA® or BCaBA®. For a broader look at how ASD insurance coverage laws vary across states, we’ve put together a complete state-by-state guide.
Practicing Applied Behavior Analysis in Illinois
ABAs in Illinois work with adults and children across a wide range of behavioral conditions, including autism spectrum disorder (ASD), ADHD, depression, anxiety, learning disorders, and developmental disorders. Services typically include early intervention, family support, group therapy, staff training, structured programming, and behavior modification.
Because of the ongoing increase in ASD diagnoses among school-age children, many ABAs in Illinois work primarily with that age group. This calls for both clinical skill and the ability to coordinate care with parents, teachers, and other providers. When working in schools, ABAs participate directly in evaluating special needs students and helping develop Individual Education Plans (IEPs).
One important note on licensing scope: individuals working as learning behavior specialists or school support personnel with an endorsement from the State Board of Education or particular school districts are exempt from the LBA/LABA requirement. And according to ILABA, enrolled Behavior Intervention Services providers with IDHS at Level 1 or Level 2 won’t require an LBA/LABA license, but anyone who describes themselves as an LBA or LABA must get licensed to keep practicing.

Professional Resources for ABAs in Illinois
The Illinois Association for Behavior Analysis (ILABA) is the state’s professional association for behavior analysts, providing job listings for members and serving as the Illinois chapter of ABAI. Membership costs $60 per year and includes professional magazine subscriptions, access to an annual conference, and input on organization activities. ILABA was instrumental in getting the state licensure legislation passed and remains one of the best resources for staying current on implementation details.
Salary and Career Outlook for Behavior Analysts in Illinois
Illinois is a strong market for behavior analysts, both in terms of job volume and pay. The state employed 18,170 substance abuse, behavioral disorder, and mental health counselors as of May 2024.
