Pennsylvania continues to face significant demand for addiction counseling services, including services related to opioid use disorder. If you’re looking to enter this field or move up within it, the Pennsylvania Certification Board (PCB) is the governing body you need to know. PCB offers four certification levels, each tied to a specific education requirement and set of clinical experience hours. This guide covers what each credential requires, how to apply, what the exams involve, and what counselors in this field earn. Master’s-level counselors pursuing the CAADC may also be eligible for full Licensed Professional Counselor (LPC) licensure in Pennsylvania.
PCB is affiliated with IC&RC for reciprocal addiction credentials. NAADAC’s Pennsylvania chapter may offer additional professional resources for working counselors.

A few things worth knowing before you choose a starting point: the AAC is an entry-level credential with no exam requirement, designed for counselors who want to begin building toward full certification. The CADC experience requirement depends on your degree field. PCB lists 4,000 hours for a relevant bachelor’s degree and 6,000 hours for a non-relevant degree. Applicants should confirm whether their degree is considered relevant before planning hours. Work experience must have been completed within the last seven years, and positions like case manager, technician, peer specialist, or intake/admissions staff do not count toward the clinical experience requirement.
Education Requirements
The AAC and CAAC don’t require a college degree, though the CAAC accepts an associate degree in addition to a high school diploma or GED. Both require documented education and training in addiction counseling: 100 hours for the AAC (including 6 hours in ethics) and 300 hours for the CAAC (including 100 hours specific to substance use disorders and 6 hours in ethics).
The CADC requires a bachelor’s degree at a minimum. PCB doesn’t specify a required field of study, but your degree field affects how many clinical hours you’ll need. PCB lists 4,000 hours for applicants with a relevant bachelor’s degree and 6,000 hours for those with a non-relevant degree. Applicants should confirm whether their degree is considered relevant before planning hours.
The CAADC requires a master’s degree in a relevant field, along with 180 hours of education and training specific to the CAADC domains, including 6 hours in ethics. PCB states the minimum is a master’s degree in a relevant field. Applicants should verify degree-field eligibility directly with PCB before applying.
Experience Requirements
All work experience must involve primary, direct clinical substance use disorder counseling in a supervised setting. PCB requires a current job description signed by both you and your clinical supervisor at the time of application. Hours must fall within the past seven years.
Positions that don’t qualify include case managers, technicians, peer and recovery counselors or specialists, and intake or admissions staff. The experience must involve providing actual addiction counseling, not support roles adjacent to it.
Supervision hours are verified through on-the-job clinical supervision, with a minimum of 10 hours per counselor domain. Here’s what each level requires:
- AAC: 100 on-the-job supervision hours, minimum 10 hours per counselor domain
- CAAC: 300 on-the-job supervision hours, minimum 10 hours per counselor domain
- CADC: 200 on-the-job supervision hours, minimum 10 hours per domain
- CAADC: 100 on-the-job supervision hours in the specific CAADC domains, minimum 10 hours per domain

Application fees vary by credential level. The current fees listed on the PCB site are: AAC is $125, CAAC and CADC are $375, and CAADC is $275 if you already hold a CADC or $375 if you don’t. Verify current fees directly with PCB before submitting, as these are subject to change.
Exam Requirements
Once your application is approved, PCB will contact you to schedule the exam. The AAC has no exam requirement. It’s the only credential in the PCB system without one.
The CAAC and CADC both require the IC&RC Alcohol and Drug Counselor (ADC) Exam. The CAADC requires the IC&RC Advanced Alcohol and Drug Counselor (AADC) Exam. Both exams are administered by the International Credentialing and Reciprocity Consortium (IC&RC), which also publishes candidate guides to help you prepare.
If you need to cancel or reschedule your exam, PCB charges a $175 fee. Exam study materials are available through IC&RC Exam Prep. After passing, expect your certificate to arrive in 5–10 business days.
Candidate guides for both exams:
Renewal
All PCB certifications renew every two years. The continuing education requirement is 40 hours relevant to addiction, including 3 hours in ethics. Renewal fees are $100 for the AAC and $200 for the CAAC, CADC, and CAADC.
Renewal applications are available online through the PCB recertification page. You can submit by mail or email. PCB also offers inactive and emeritus status options for counselors who need to pause active practice.

Frequently Asked Questions
Which PCB certification should I start with if I don’t have a college degree?
The AAC (Associate Addiction Counselor) is the right starting point. It requires only a high school diploma or GED, one year of qualifying clinical work experience, and 100 hours of training. There’s no exam requirement. Many counselors use the AAC as an entry point while working toward the CAAC or building their educational credentials.
How long does it take to become a CADC in Pennsylvania?
If you’re starting from a bachelor’s degree in a relevant field, the CADC typically takes two to three years, the time needed to accumulate 4,000 clinical hours under supervision. With a non-relevant bachelor’s degree, plan for three years or more to reach the 6,000-hour threshold. Most candidates work full-time in a qualifying position while meeting the experience requirement.
Does Pennsylvania certification transfer to other states?
The AAC, CAAC, CADC, and CAADC are IC&RC credentials, which means they may be eligible for reciprocity through IC&RC member boards in other jurisdictions. Transfer is not automatic, and other states or territories may impose additional requirements. You can find current reciprocity information on the PCB reciprocity page.
What positions don’t count toward the work experience requirement?
PCB is specific about this: case managers, technicians, peer and recovery counselors or specialists, and intake or admissions staff do not qualify. Your experience must involve primary, direct clinical substance use disorder counseling in a supervised setting. When in doubt, PCB recommends contacting the office at [email protected] before logging hours in a role you’re unsure about.
