What Is RAS II?

What Is RAS II, Exactly?

RAS II stands for Advanced Registered Addiction Specialist - Level II, a credential on the Registered Addiction Specialist (RAS) career track offered through Breining Institute. If you've searched for a plain-language answer to what is RAS II or wondered what does RAS II stand for, this is the definitive answer as it applies to this specific credential: RAS II is an advanced designation built on top of the standard RAS credential, not a stand-alone certification with its own separate exam.

This distinction matters because several unrelated credentials also use the initials "RAS II." This article, and the entire RAS II Exam Prep site, is exclusively about the Breining Institute addiction-counseling designation. Every fee, requirement, and domain name referenced here comes directly from Breining's published RAS career track materials.

Who Administers RAS II and the ACE Exam

Breining Institute is the certifying body for the entire RAS career track, including RAS II. The qualifying examination used across this track is the Addiction Counselor Exam (ACE). Candidates pursuing entry-level RAS sit for the ACE as part of their initial application; candidates who already hold RAS and are upgrading to RAS II do not repeat the exam. Instead, the RAS II upgrade is evaluated through documented experience and education hours submitted with the application.

For a deeper dive into how the certification itself is structured, see RAS II Certification and the related overview at What Is RAS II Certification?. If you're still getting oriented to terminology, RAS II Meaning and What Does RAS II Mean? cover the naming conventions in more detail.

RAS II Eligibility Pathways

Unlike entry-level RAS, which requires 155 formal alcohol-and-other-drug education hours plus one year (2,000 hours) of clinical experience, RAS II eligibility is designed for practitioners who have already accumulated significantly more field time and coursework. Every applicant also needs an underlying recognized healthcare-professional license or certification - RAS II is layered on top of an existing professional credential, not a substitute for one.

Breining recognizes three separate routes into RAS II eligibility:

In every pathway, clinical experience must be formally documented - verbal attestation is not sufficient. Because the eligibility math can be confusing across these three routes, it's worth reading the full breakdown in RAS II Requirements 2026: Eligibility, Prerequisites & How to Qualify before you start assembling paperwork.

Exam Format, Scheduling, and Fees

For candidates who are pursuing entry-level RAS on their way toward an eventual RAS II upgrade, the ACE is delivered online from the candidate's own device, which removes the need to travel to a physical testing center. Requesting the exam requires submitting a current candidate photo. Once requested, the exam must be taken within one month, and if you need to reschedule, Breining requires at least 24 hours' notice.

The fee structure is straightforward and fixed:

A qualifying RAS II upgrade during renewal carries no additional upgrade fee, which makes the advanced designation relatively efficient to obtain once you meet one of the three eligibility pathways above.

The 32 ACE Content Domains RAS II Candidates Must Know

The ACE is organized around 32 content-area domains defined by Breining Institute. These domains form the backbone of everything a candidate on the RAS or RAS II track needs to master, and understanding their scope is one of the clearest ways to judge how hard the RAS II exam actually is.

The domains span foundational history, clinical counseling technique, specialized populations, and professional ethics. A sample of the breadth involved:

• Domain 1: History and Overview - the origins and evolution of addiction counseling as a field.
• Domain 10: Physiology and Pharmacology of Addiction / Co-occurring Disorders / PTSD - how substances act on the body and brain, and how co-occurring conditions complicate treatment.
• Domain 16: Gambling Disorders and Domain 17: Sexual Addiction - process addictions that require different intervention frameworks than substance use.
• Domain 21: Individual Counseling, Domain 22: Group Counseling, and Domain 23: Family and Couples Counseling - the core modalities counselors apply day to day.
• Domain 30: Laws, Ethics and Confidentiality and Domain 31: Prevention of Sexual Harassment - the compliance and conduct standards every credentialed counselor is expected to uphold.
• Domain 32: Standards for Counselor Competency and Assessment Methods - how the field measures whether a counselor is practicing competently.

Because all 32 domains carry real weight on the ACE, candidates benefit from a domain-by-domain breakdown rather than generic review. The full domain guide at RAS II Exam Domains 2026: Complete Guide to All 32 Content Areas maps each of these areas to practical study focus points.

Who Hires RAS II Holders

RAS II is designed for practitioners who already hold a recognized healthcare-professional license or certification and want to layer addiction-specific credentialing on top of it. In practice, this makes the designation relevant to nurses, counselors, social workers, and other licensed clinicians working in settings such as outpatient treatment programs, residential recovery facilities, hospital-based behavioral health units, and employee assistance programs - a setting directly reflected in Domain 8 of the ACE content outline. Because RAS II sits on top of an existing license rather than replacing one, it functions as a specialization marker that signals advanced, documented experience in addiction-specific care.

Official Preparation Materials

Breining Institute points candidates toward a specific, narrow set of official preparation resources rather than a broad library of third-party study guides. These are:

• The Addiction Professional, fourth edition (2022) - the core reference text aligned to the ACE content areas.
• TAP 21 - a foundational government publication on addiction counseling competencies.
• The MAT Counselor - supplemental material addressing medication-assisted treatment content.
• Breining's tutorial videos - official video walkthroughs of exam content.

Candidates should always check the edition-update notes that accompany the tutorial videos, since Breining periodically updates guidance to reflect the current edition of the reference text. Treating these four resources as your primary source material - rather than generic addiction-counseling study guides pulled from unrelated certifications - is the single most important preparation decision you'll make.

Mapping Study Time to Domains

With 32 domains to cover, an unstructured read-through of the reference materials tends to leave gaps. A more effective approach groups related domains into weekly blocks so review time mirrors how the ACE actually clusters its content areas.

Spacing repeated review sessions across these four blocks - rather than cramming every domain in the final week - gives you multiple passes over the highest-density clinical domains (10-19) where physiology, pharmacology, and disorder-specific knowledge tends to be most detailed. For a fuller walkthrough of this kind of structured plan, see the RAS II Study Guide 2026: How to Pass on Your First Attempt, and pair it with focused practice sessions on our RAS II practice test platform to check retention domain by domain.

Renewal and Maintaining RAS II

RAS II credential holders renew every two years and must complete 30 continuing-education hours during that period. On-time renewal costs $275, though candidates who meet the qualifying continuing-education discount pay $225 instead. Because a qualifying RAS II upgrade completed during renewal carries no additional upgrade fee, practitioners who are already tracking toward RAS II eligibility can often fold the upgrade into a normal renewal cycle without extra cost.

Keeping documentation organized - continuing-education certificates, clinical-hour logs, and license renewal proof - makes each two-year renewal far less stressful than scrambling at the deadline.
