Do you need a license to practice ABA in Colorado?

Is ABA licensed in Colorado

Yes, as of 2026, though the requirement is not yet in force. Colorado was for years among the minority of states without behavior-analyst licensure, after a 2020 sunrise review by the Office of Policy, Research, and Regulatory Reform found insufficient evidence of consumer harm to justify it (2020 COPRRR Sunrise Review). The legislature reversed that in 2026: the Applied Behavior Analysis Practice Act, signed June 2, 2026, added article 247 to title 12 and created the Colorado Behavior Analyst Licensing Board within the Division of Professions and Occupations, with licensure built on a current certification from a certifying entity such as the BACB (HB26-1425). The practice license is required on and after July 1, 2028. The practical consequence for today is a transition: until that date there is no license to hold, so BACB certification and payor credentialing still govern, but the practice should plan for state licensure on the 2028 timeline.

The credential tiers without a state license

Until the license requirement takes effect in 2028, the tiers that organize an ABA practice are national BACB credentials rather than state licenses. The new act builds licensure on top of that certification, so the credential structure carries forward.

Today the authority comes from the private national certification rather than a Colorado license. From July 1, 2028 the state license sits on top of it, so the structure converges with that of a licensed state.

Why BACB certification remains the credential

Until the license requirement takes effect, BACB certification carries the weight. It is the credential Colorado employers hire against and the credential payors require before they will reimburse ABA. It also becomes the foundation of the state license: the new act builds licensure on a current certification from a certifying entity, with the BACB and QABA named among them (HB26-1425). Maintaining current certification in good standing is therefore both the present gate and the on-ramp to the 2028 license. Lapsing on certification will cut off the ability to be credentialed and paid, and will complicate licensure when the requirement arrives.

What it takes to practice

Until July 1, 2028, the requirements that govern practice are the BACB's, the qualifying graduate degree, coursework, supervised fieldwork, and examination for the relevant certification, plus whatever each payor requires for credentialing. No state coursework rule, supervised-hours verification, or state examination is layered on top yet. From that date the state license applies, and because the act builds it on a current certification from a certifying entity, the certification pathway remains the substantive route rather than being replaced. Watch the Colorado Behavior Analyst Licensing Board for the implementing rules, application process, and fees as the date approaches.

Title, scope, and the psychotherapy overlap

Title protection arrives with the license. Until the 2028 requirement takes effect, Colorado does not protect a behavior-analyst title, and scope questions run through the state's legal definition of psychotherapy under its mental-health practice framework; providers whose work meets that definition have historically intersected with the Unlicensed Psychotherapist regime, discussed below. Once the Applied Behavior Analysis Practice Act is in force, practice without a license becomes an offense and the profession has its own regulatory home in the new board, which supersedes the psychotherapy workaround as the governing frame for ABA.

Supervision rules

Supervision in Colorado currently follows the BACB's standards rather than a state supervisor-licensure rule, so there is no state-licensure condition on supervisors of behavior-analytic fieldwork today. That is likely to change as the new board issues its implementing rules ahead of the 2028 date, since licensed states commonly require supervisors to hold the state license where the trainee delivers services. Candidates accruing fieldwork in Colorado should follow the BACB rules precisely, since those hours support the certification that both current practice and the coming license depend on, and should watch the board for any supervisor requirements it adopts.

Maintaining the credential

There is no Colorado license to renew yet. Maintenance today means keeping BACB certification current on the BACB's cycle, including its continuing-education and ethics requirements, and keeping payor credentialing current through periodic revalidation. From July 1, 2028 a state renewal cycle joins that calendar, on terms the Behavior Analyst Licensing Board sets. For now the dates to watch are the BACB recertification cycle and each payor's revalidation schedule, plus the board's rulemaking as the licensure date approaches.

Getting credentialed with payors

This is the step that actually gates practice and payment in Colorado. After confirming BACB certification, a provider or practice enrolls with Colorado Medicaid, known as Health First Colorado, and credentials with commercial health plans, most of which draw provider data from CAQH. Colorado payors generally require BACB credentials for the behavior analysts and assistant behavior analysts delivering and supervising services, and credentialing is followed by periodic revalidation. The entity that bills and its ownership are disclosed during enrollment, which is where credentialing meets the entity and ownership questions covered elsewhere in this guide. What each payor covers and pays for ABA is addressed on the Medicaid and insurance page.

Colorado-specific wrinkles

Two Colorado developments sit alongside the new licensure regime and should be confirmed with counsel, because they concern authorization to practice in the interim. First, where ABA falls within Colorado's psychotherapy definition, providers historically registered as Unlicensed Psychotherapists with the Department of Regulatory Agencies, but in 2022 the state discontinued new Unlicensed Psychotherapist registration (HB22-1307). The dedicated behavior-analyst license supersedes that path for ABA as the 2028 date approaches, but scope and current registration status are worth verifying directly in the meantime. Second, Colorado is moving its behavioral-health providers toward a Behavioral Health Entity licensing structure under the Behavioral Health Administration, which can impose entity or facility licensure on behavioral-health services. That is a facility-level question rather than a personal-credential one, and it is covered on the facility page.

How this connects to the rest of your compliance stack

The licensure change ripples into the rest of the structure, though less than you might expect:

• Entity and ownership. Licensure does not close ownership. The act licenses individuals and imposes no professional-entity requirement or ownership cap, and the corporate-practice doctrine remains medicine-specific, so a standard LLC owned by a non-licensee can still operate the practice. See the Colorado entity page and the Colorado ownership page.
• Medicaid and insurance. Credentialing is the gate; coverage and rates are separate. See Medicaid and insurance mandates.
• Facility and behavioral-health entity status. The Behavioral Health Entity transition can reach ABA providers. See facility licensure and HIPAA.

Practicing and getting paid in Colorado: the sequence

1. Obtain and maintain BACB certification. The relevant BACB credential governs today and becomes the foundation of the state license from July 1, 2028.
2. Confirm your scope against the psychotherapy definition. Check whether your work falls within Colorado's psychotherapy definition and what that implies for registration.
3. Credential with Health First Colorado. Enroll with Colorado Medicaid, which requires BACB credentials for delivering and supervising providers.
4. Credential with commercial plans. Credential through CAQH and each plan, then plan for revalidation.
5. Screen the behavioral-health entity question. Confirm whether the Behavioral Health Entity licensing structure applies to your practice.
6. Track the BACB, payor, and licensure calendars. Watch the BACB recertification cycle, each payor's revalidation date, and the Behavior Analyst Licensing Board's rulemaking ahead of the July 1, 2028 license requirement.
