How to get CAS certification in Colorado: steps, requirements, and boards

You've decided addiction counseling is the work you want to do. Pull up Colorado's certification information, though, and you're suddenly looking at three credentials. CAT, CAS, LAC. Different degree requirements, different exam obligations, and references to a state behavioral health board that can be hard to track down. Figuring out which tier applies to you, and what the application actually requires, can burn up a lot of time before you take a single practical step.

Colorado's three-tier credential system

Colorado addiction counselor credentials run in three tiers, and your entry point depends almost entirely on your current educational background. According to addiction-counselors.com, the state structures it this way:

• The CAT (Certified Addiction Technician) requires a high school diploma.
• The CAS (Certified Addiction Specialist) requires a bachelor's degree.
• The LAC (Licensed Addiction Counselor) requires a master's degree.

Each tier comes with more clinical autonomy and generally higher pay than the one below it. The CAT suits people who want to start working in the field before finishing a degree. The CAS is where you aim with a bachelor's, or while finishing one. The LAC, which requires a master's, has the widest clinical scope.

The tier structure shapes your timeline directly. If you're mid-way through a bachelor's, you're already on the CAS track and can start mapping requirements now. If you hold a master's, going directly to the LAC skips unnecessary steps.

Educational requirements: what the CAS takes

The CAS starts with a completed bachelor's degree, but that's not the whole requirement. According to the University of Colorado Colorado Springs (UCCS), the credential also requires specific substance use courses and supervised fieldwork hours on top of the degree.

You can't just earn any bachelor's degree and expect it to satisfy the credential requirements. The coursework has to cover substance use counseling competencies defined by the state. If you're choosing a program with the CAS in mind, checking whether its curriculum aligns with Colorado's credentialing requirements can save you from filling gaps after graduation.

Supervised fieldwork is a separate component, and where those hours happen matters. That connects directly to the BHA requirement described below.

For context on what addiction counselors actually do in clinical settings, the guide on how substance abuse treatment works covers the clinical structure of treatment programs, from initial assessment through discharge planning.

The BHA's role in training approval

The Colorado Behavioral Health Administration, known as the BHA, sets the core curriculum standards that addiction counselor training programs must meet. Per UCCS, some required substance use courses must be completed at a BHA-approved clinical training site, not just any accredited school.

A course from a non-BHA-approved program may not count toward your CAS application, even if the content looks identical on paper. Confirming approval status before enrolling is a necessary first step, not something to sort out afterward.

The same applies to fieldwork placements. The BHA site requirement means you can't fulfill supervised hours at any clinical setting you happen to arrange. The site itself needs the relevant approval. Many training programs place students at pre-approved sites automatically, but if you're arranging your own fieldwork, checking approval status first protects the hours you're putting in.

The state exam: what to expect

Colorado requires passing state examinations at all credential levels, including the CAS. Per addiction-counselors.com, this requirement applies across all three tiers. The specific exam name for the CAS is not identified in current publicly available state materials.

Confirm the exam name and format directly with the Colorado credentialing body before starting your application. Requirements can change, and secondhand information can be months or years out of date by the time you apply. Going to the source saves real trouble later.

IC&RC reciprocity: what it means if you already hold a credential

If you're moving to Colorado from another state and already hold an addiction counseling credential, you may not need to start the process from scratch. Colorado is a member of the International Credentialing and Reciprocity Consortium (IC&RC). That means IC&RC reciprocity credentials such as the ADC (Alcohol and Drug Counselor) or the AADC (Advanced Alcohol and Drug Counselor) are recognized for endorsement to a comparable Colorado credential, according to addiction-counselors.com.

Endorsement isn't automatic approval. You still go through an application process, but you're applying for recognition of an existing credential rather than building one from the ground up. For counselors moving their practice to the Western Slope region, this path can meaningfully reduce the time to active licensure.

The IC&RC membership also works in the other direction. A Colorado CAS credential can later be endorsed in other IC&RC member states if you relocate, so the credential has portability beyond Colorado's borders.

Clinical privileges: why the tier you hold matters day to day

The tiers differ in what you can actually do on the job, not just in what the credential is called. The LAC has full clinical privileges. The CAS has more than the CAT but less than the LAC. The CAT has the most constrained scope. According to addiction-counselors.com, each level carries expanding clinical privileges as you move up through the tiers.

The specific lines between CAT and CAS privileges, and between CAS and LAC, are determined by the state and by the practice setting where you work. Some treatment programs require supervisory oversight for certain clinical activities at the CAT level that a CAS can perform independently. Similar constraints may exist between CAS and LAC depending on the context.

Worth clarifying where those lines fall in your specific practice setting before choosing a credential target. If the clinical work you want to do requires LAC-level privileges, going directly to the LAC is the cleaner path, assuming you hold a master's. If you don't, the CAS is the right next step.

If you're still deciding whether addiction counseling fits, the guide on understanding addiction covers how substance use disorders develop and what treatment approaches have actual research behind them, both worth reading before committing to a credential path.
