Substance Abuse Counselor Requirements in Nevada: Credentials, Hours and Exams

Chapter 641C provides state certificates for the alcohol and drug counselor and for the clinical and non-clinical counselor interns, and licences for the alcohol and drug counselor and the clinical alcohol and drug counselor — all issued by the Board of Examiners for Alcohol, Drug and Gambling Counselors.

The naming runs against intuition: the bachelor's-level credential is the certified Alcohol and Drug Counselor (CADC), and the master's-level credential is the licensed Alcohol and Drug Counselor (LADC).

The licensed Clinical Alcohol and Drug Counselor (LCADC) is the separate co-occurring licence.

Practice is gated by NRS 641C.900: outside the exemptions, counseling persons with substance use disorders requires being a licensed counselor, certified counselor or certified intern.

Intern certificates run 6 months and are renewable, but a provisional credential issued to an exam applicant is valid not more than 6 months and may not be renewed.

The rule reserves the initials CADC, LADC, LCADC and NACADC to Board holders.

The intern certificate takes three routes: bachelor's-program enrollment with at least 60 credits completed, master's or doctoral enrollment, or a degree with at least 18 SUD-specific credit hours — plus 6 confidentiality and 6 ethics hours.

The CADC's floor is a bachelor's in a board-approved social science field, which NRS 641C.390(2) waives for counselors under federal contract or grant to serve populations authorized under 25 U.S.C.; NAC 641C.276 fills in the substitute: a high school diploma or GED plus 270 hours of Board-approved formal education (at least 10 hours in each of 12 listed skills), or a credential from the Southwest Indian Substance Abuse Certification Board or the Northwest Indian Council on Chemical Dependency.

That Native American Alcohol and Drug Counselor serves only those federal populations, counts an associate's degree as 1,000 supervised hours (NAC 641C.276(4)), and holds reserved initials NACADC; only Indian-board credential holders may certify without the exam (NAC 641C.277).

The LADC requires a master's or doctorate in a board-approved social science field; the LCADC requires one with comprehensive clinical mental-health course work including diagnosis.

The CADC takes 4,000 hours of supervised counseling of persons with alcohol and other substance use disorders.

The LADC's degree route takes 3,000 hours; its second route takes 1,000 for applicants already licensed as a clinical social worker, clinical professional counselor, marriage and family therapist, a master's- or doctoral-prepared nurse, or as a clinical alcohol and drug counselor.

The LCADC requires a Board-approved program of at least 3,000 hours of supervised, postgraduate counseling — at least 1,500 with co-occurring clients, at least 1,000 with SUD clients and at least 500 of either — while its second route accepts an LCSW, MFT, clinical professional counselor or master's/doctoral nurse with at least 6 months of Board-approved supervised SUD counseling; the licensed clinical ADC is not in that 6-month group.

Coursework credit: NAC 641C.205 treats a bachelor's with 18 semester SUD hours, or a graduate degree with 12, as 2,500 completed hours toward the CADC or LADC, and 6 SUD plus 6 co-occurring semester hours as 1,250 plus 1,250 toward the clinical licence.

Each applicant for a Nevada counselor licence or certificate must pass written and oral examinations covering the practice, the chapter and its regulations — the clinical licence's exam covers the clinical practice.

The requirement carries its own exceptions: NRS 641C.290(1)–(2) excepts the substantially-equivalent waiver in NRS 641C.300 and the endorsement sections 641C.3306, 641C.356 and 641C.396, so exam-free entry runs only through those routes.

The intern certificates in NRS 641C.340 and 641C.420 carry no examination at all.

The rule sets the pass mark at an average score of at least 70 percent, and an applicant who fails three times may not retest until appearing before the Board, which must examine applicants at least twice a year.

The exam vendor: Not stated in the sources read.

A supervisor must hold a Board licence or certificate, be in good standing and not under any Board investigation, have completed a Board-approved supervisor training course, and hold a certificate as a supervisor of certified interns — available after at least 2 years of practice for an LADC, LCADC or certified problem gambling counselor, or 3 years for a CADC.

A supervisor may not reside with, have an intimate relationship with or be related to the intern, may not have had the intern as a client, and may not supervise more than five certified interns at one time without the prior approval of the Board.

Supervision means at least 1 hour of individual communication every week, unless the Board specifically directs a different schedule.

Interns may provide services only at a treatment agency while the supervisor is physically present or supervising through a secure electronic method, or at the supervisor's own practice.

Hours logged under an unapproved supervisor or agreement do not count, and the internship must be completed within 5 years unless the Board grants an extension.

All three counselor credentials may diagnose or classify a person as having an alcohol or other substance use disorder, and each may conduct testing for which the counselor was trained.

The LADC's line is firm: an LADC may not identify, evaluate, diagnose or treat a mental illness when a person with mental illness also has an alcohol or other substance use disorder.

The LCADC's clinical practice reaches mental illness in co-occurring clients — identification, evaluation, diagnosis and treatment — but excludes the diagnosis or treatment of a psychotic disorder and the use of a psychological or psychometric assessment test to determine intelligence, personality, aptitude and interests (641C.065(2)).

On supervision, a CADC may take on intern supervision after being certified at least 3 years and meeting the Board's regulatory requirements; an LADC may supervise certified alcohol and drug counselor interns only, while an LCADC may supervise both intern types.

Interns practice and diagnose only under the supervision their certificates require — and a clinical intern's supervisor must be an LCADC.

The Board may endorse a counselor holding a corresponding valid and unrestricted licence or certificate in the District of Columbia or any state or territory, with expedited sections for the clinical licence (641C.3306), the LADC (641C.356) and the CADC certificate (641C.396).

Applicants must prove they hold that credential, have not been disciplined or investigated by the corresponding authority, and have not been held civilly or criminally liable for malpractice anywhere in the United States, plus fingerprints, an affidavit and fees; the Board requests more information within 15 business days and decides within 45 days of receiving it.

The without-exam path in NAC 641C.225, tied to NRS 641C.300, applies only where the Board deems the other jurisdiction's requirements at issuance substantially equivalent to Nevada's; it demands proof of good standing, proof of the degree at issuance, and satisfaction of Nevada's own requirements.

Active Armed Forces members, their spouses, veterans and surviving spouses pay not more than one-half of the initial issuance fee.

IC&RC reciprocity does not fill the gap: its footnote scopes the bar to ADC and AADC credentials.

Licences and certificates are valid for 2 years and renewable.

Each two-year period requires at least 40 hours of continuing education, including at least 3 hours on ethics and at least 3 on confidentiality standards, and NRS 641C.450(3) adds at least 3 hours of instruction on cultural competency and diversity, equity and inclusion for each year of the term.

Interns train as they go: at least 12 hours in the first 6 months — 6 on ethics and 6 on confidentiality — at least 10 in the second 6 months, and at least 20 in each subsequent year.

A licence not renewed on time becomes delinquent and must be renewed within 60 days with a delinquency fee; after that it expires, and restoration requires the application, the back fees, evidence of the CE — and passing the oral and written examinations again.

The amendment histories in the sections read date three recent changes.

NRS 641C.331, amended in 2023, adds the conditions for an LCADC to supervise certified problem gambling counselor interns: Board approval plus at least 30 hours of problem-gambling instruction and 12 hours of supervision instruction.

NRS 641C.450, the renewal and CE section, was amended in 2023 and 2025; its current text carries the cultural-competency requirement.

NRS 641C.130, the exemption list, was amended in 2025, including by the 36th Special Session; the items stated above reflect the list as it now stands.

The saved rules carry their own histories: the supervisor rules (NAC 641C.280, 641C.285) were last amended by R069-17, effective February 27, 2018, while NAC 641C.250 and 641C.290 (intern location, initials, hours) were amended again by R046-21, effective February 28, 2022, and a reviser's note says R058-14's amendments to the 5-year provision in NAC 641C.290(5) do not apply to anyone who applied to become a certified intern before December 22, 2014.
