Substance Abuse Counselor Interview Questions to Ask
The letters on a counselor's resume don't tell you the tier, the issuer, or what the credential lets them do.
These questions test exactly that — and the judgment your caseload needs.
No two substance abuse counselors carry the same credential.
One holds a state licence (Texas's LCDC), one a state-issued certificate (New York's CASAC), one a private certification (Illinois's CADC) — and the same letters can sit at different tiers even in neighbouring states.
So an interview for this role has two jobs at once: verify what the candidate's credential actually is and does, and test the competency behind it.
The questions below are grouped by competency, each with what a strong answer tends to include.
Ask the same core set of every candidate so you can compare answers, not impressions.
Before the interview
Verify the credential before you meet — and know who issues it.
There is no national addiction-counselor credential: 33 jurisdictions issue a state licence at one or more tiers, 6 issue a state certificate or credential, and 12 states rely on private certification (the classification behind this site's 51-jurisdiction credential pages, September 2026 research pass, counting a state as a licence state when any counselor tier is a licence).
Confirm the credential, the tier and the status in the issuing body's own directory — a state board (Texas's LCDC), a state agency (New York's OASAS for the CASAC), or a named private board (an IC&RC member board — IC&RC itself does not certify individuals; its member boards do) — and record the check.
See hiring compliance: license verification and exclusion checks.
Decide the tier the role needs, and the scope lines that come with it.
The same letters mean different tiers in different places — "CADC" is a state certificate in Connecticut, a private certification in Illinois, and a three-tier ladder (CADC I–III) in Oregon; the CADC vs LADC vs LCDC vs CAC title map decodes your state's letters.
Then match duties to tier: state scope lines differ sharply — in Louisiana, certified and registered addiction counselors may not render a diagnostic impression, and only the LAC may practise autonomously, apart from a CAC providing addiction counseling services in a prison or other custodial environment; Ohio reserves "diagnose and treat" for the LICDC; Texas rules state that LCDCs "are not qualified to treat individuals with a mental health disorder"; Kentucky defines the practice of alcohol and drug counseling so that it does not include diagnosing or treating a mental health condition.
These are state examples, not a national rule — your state's lines govern, and what a CADC can diagnose or bill walks through them.
Credential, tier and scope
Walk me through your credential: the exact letters, the tier, and who issued it.
What to listen for: The issuing body named precisely — a state board (Texas's LCDC), a state agency (New York's OASAS for the CASAC), or a named private board that is an IC&RC member board — plus where the credential sits on the state's ladder (Oregon runs CADC I–III; Ohio runs LCDC II → LCDC III → LICDC).
A candidate who cannot name their issuer, or whose letters don't match the issuer's directory, is a verification problem before it is a competence problem.
What does your credential let you do in [state], and what is the next tier allowed to do that you can't?
What to listen for: They know where their scope stops and can name the line.
State scope lines differ sharply: a Louisiana certified or registered addiction counselor may not render a diagnostic impression, and only the LAC may practise autonomously, apart from a CAC providing addiction counseling services in a prison or other custodial environment; Ohio reserves "diagnose and treat" for the LICDC and its LCDC III diagnoses only under supervision; Kentucky's practice definition excludes diagnosing a mental health condition.
A candidate who says their exam covered diagnosis, so they can diagnose, is citing exam content as authority — exam blueprints test knowledge; state law grants scope.
Assessment and level of care
How do you approach an intake — what are you trying to establish in the first session or two?
What to listen for: A structured approach to screening and assessment rather than an unstructured conversation, attention to what the client wants from treatment, and an understanding that the assessment drives the treatment plan — not the other way round.
Strong candidates describe how they adjust pace and style for a client who arrives ambivalent or mandated.
Tell me about deciding a client's level of care. How do you decide, and what do you do when the right level has no opening?
What to listen for: Placement driven by the assessment, familiarity with a level-of-care framework where your program uses one (many SUD programs and payers reference the ASAM Criteria), and honesty about what happens when the right level is unavailable — referral, a monitored waitlist, escalation to a supervisor — rather than quietly stretching the program to fill a slot.
Group facilitation and caseload
Which groups have you run — topic, format, size — and how do you handle a client who dominates or one who stays silent?
What to listen for: Specific groups (psychoeducation, relapse prevention, process), concrete facilitation moves rather than generalities, and materials or curricula they actually use.
Be wary of a candidate who has only ever co-facilitated and cannot describe a group of their own.
Our expectation is [number] clients on caseload, with a [individual/group] mix. How does that compare with what you carry now?
What to listen for: An honest comparison, questions about how no-shows and documentation time are handled, and specific needs (a ramp-up period, scheduling support).
A candidate who agrees to any number without asking how the caseload is supported may not have thought it through.
Documentation and confidentiality
How do you keep notes current, and what does a note need to hold up in a program like ours?
What to listen for: A realistic routine (same-day or next-day notes), notes tied to the treatment plan that can support a funding or utilization review, and awareness that thin or late notes put reimbursement at risk.
Compare their turnaround with the standard in your posting.
Someone calls claiming to be a client's employer and asks you to confirm the client is in your program. What do you do?
What to listen for: Substance use disorder patient records follow the federal confidentiality rule at 42 CFR Part 2, which is stricter than HIPAA in important ways — the strong answer neither confirms nor denies the client's presence without valid consent, knows the rule exists (by name or at least by instinct), and loops in a supervisor.
A candidate who would casually confirm attendance is a compliance risk you cannot train out quickly.
Supervision and tier progression
Where are you on your state's credential ladder, and what has to happen for you to move up?
What to listen for: For a trainee-tier hire, precision about what makes hours count: in Texas, a counselor intern's hours count only after registration and only at a registered CTI or under a CCS, and the supervisor must be on site until the first 2,000 hours are logged; New York's CASAC-Trainee certificate is temporary and its holders may perform assessment and diagnostic impressions only with intensive supervision, per OASAS.
For a fully credentialed hire, whether they want to supervise, and what a supervisor credential would take in your state.
Where do you want your credential and training to be in two years?
What to listen for: A plan you can support: the next tier, a clinical-supervisor credential, or a specialty your state's scope lines allow them to work toward in this role.
Mismatches here predict turnover more than salary does — a hire whose ladder your program cannot advance is already halfway out the door.
Red flags
Any one of these is worth a follow-up question; several together are a reason to pass.
- Cannot name the issuing body of their own credential, or the issuer's directory shows a different tier or status than the resume claims.
- Cannot say whether their credential is a state licence, a state certificate, or a private certification.
- Describes independent or diagnostic work their tier's scope lines don't allow — or cites exam topics as the source of that authority.
- Would confirm a client's presence in the program to an outside caller without checking consent first.
- As a trainee-tier hire, is vague about whose supervision counts and which hours count toward the next tier.
- Talks about clients in identifiable detail or speaks about them dismissively.
After the interview
Score each candidate against the same competencies, not overall impression, and check references with a direct supervisor where you can.
Before the offer, re-verify the credential with the issuing body and record the check; if the role touches federally funded programs, search the OIG exclusion list too — no statute requires you to run the check, but the law bans employing an excluded person in federally paid work, and OIG's guidance says monthly screening best minimizes the liability.

Before the first note is written, walk the hire through your records rules: substance use disorder patient records follow the federal confidentiality rule at 42 CFR Part 2, which is stricter than HIPAA in important ways — our Part 2 explainer covers what changes.
Confirm the pay structure in writing.
Many substance abuse counselors are hired at certificate, registered or bachelor's tiers that generally fail the learned-professional duties test for the FLSA overtime exemption, so treat those hires as non-exempt from the start; a master's-level counselor hired for independent clinical work needs a salary basis of at least $684 a week under the rules DOL restored in May 2026.
To budget, use BLS SOC 21-1018 — a combined series covering substance abuse, behavioral disorder and mental health counselors, so no SUD-only wage exists: national median $59,350, middle 50 percent $47,100–$76,530 (BLS OEWS May 2025, all industries).
