ASL Certification Requirements by State: Full Guide

If you are pursuing a career as an ASL interpreter, understanding ASL certification requirements by state is essential because there is no single national standard. Each state sets its own rules for who can work as a sign language interpreter, what credentials are needed, and how the profession is regulated.

National Certification Overview

Before diving into state-specific rules, it helps to understand the national certification landscape. The Registry of Interpreters for the Deaf (RID) is the primary national certifying body for ASL interpreters in the United States.

RID offers the National Interpreter Certification (NIC), which is the most widely recognized credential. To earn the NIC, candidates must pass a written knowledge exam and a performance exam that tests both ASL-to-English and English-to-ASL interpreting skills. A bachelor’s degree is required to sit for the NIC exam.

Previously, RID offered multiple certification levels (CI, CT, CSC, CDI, and others). While these legacy certifications are still valid for holders, the NIC is the current standard exam. Certified Deaf Interpreters (CDI) earn a separate credential recognizing their specialized role as Deaf professionals who work alongside hearing interpreters.

The Board for Evaluation of Interpreters (BEI), developed in Texas and now used by several states, provides an alternative certification pathway. BEI offers multiple levels — Basic, Advanced, and Master — allowing interpreters to demonstrate progressively higher skill levels.

Many states accept national certification (RID NIC or BEI) as the basis for their state credential but add additional requirements like background checks, continuing education, or state-specific exams. Understanding both the national and state layers is key to navigating ASL certification requirements by state.

State Licensing vs. State Certification

States regulate sign language interpreters in different ways, and the distinction between licensing and certification matters for your career.

Licensed states: States with interpreter licensing laws make it illegal to work as a sign language interpreter without a valid state license. These states typically require national certification (NIC or BEI), a background check, proof of continuing education, and payment of a licensing fee. Practicing without a license can result in fines or criminal penalties. Examples include Texas, Virginia, Illinois, and Maine.

Registered/certified states: Some states maintain a registry or state certification program that is strongly recommended or required for certain work settings (like legal or medical interpreting) but not for all interpreting work. These states may allow uncredentialed interpreters to work in some contexts while restricting high-stakes settings to certified professionals.

Unregulated states: Several states have no specific licensing or registration requirements for sign language interpreters. In these states, anyone can technically call themselves an interpreter, though employers, agencies, and the Deaf community strongly prefer nationally certified professionals. The absence of state regulation does not mean credentials are unimportant — it means the market and community standards fill the regulatory gap.

The trend is clearly toward more regulation. Over the past two decades, more states have passed licensing laws, and advocacy organizations like RID and the National Association of the Deaf (NAD) continue to push for universal minimum standards to protect Deaf consumers from unqualified interpreters.

Requirements by Region

While listing every state individually would require a directory of its own, here is a regional overview of how ASL certification requirements vary across the country.

Northeast: States like New York, Massachusetts, and Maine tend to have well-established regulatory frameworks. Maine requires state licensure with national certification. New York does not require licensure for general interpreting but has strict requirements for court interpreting. Connecticut, home to the American School for the Deaf, maintains a registry with tiered credential levels.

Southeast: Several southeastern states have adopted the BEI testing system. Alabama, Georgia, Louisiana, Mississippi, and South Carolina use BEI alongside or instead of RID certification. Virginia requires state licensure, and North Carolina has a quality assurance program through its Interpreter and Transliterator Licensing Board.

Midwest: The Midwest presents a mixed picture. Illinois requires licensure and accepts both RID and BEI credentials. Indiana, Ohio, and Michigan have varying registration or certification requirements. Some midwestern states with smaller Deaf populations have limited or no regulation, creating access challenges in rural areas.

Southwest and West: Texas pioneered the BEI system and has one of the most comprehensive licensing frameworks in the country. Arizona requires state certification. California does not require general licensure but has strict requirements for educational interpreters working in K-12 schools.

Pacific Northwest: Oregon and Washington both have interpreter registration or licensing requirements. Washington state’s interpreter licensing program is often cited as a model, requiring national certification, background checks, and ongoing continuing education.

Always verify current requirements directly with your state’s licensing board or commission for the deaf, as regulations change. RID maintains a state-by-state guide on their website that is regularly updated.

Educational Requirements

Education requirements for ASL interpreter certification vary significantly across states, but the trend is toward requiring more formal education.

RID NIC requirement: Since 2012, RID has required a bachelor’s degree to sit for the NIC exam. The degree does not have to be in interpreting — any bachelor’s degree qualifies — but graduates of interpreter training programs are typically better prepared for the performance exam.

Associate degree programs: Many community colleges offer two-year interpreter training programs (ITPs) that prepare students for entry-level interpreting work. In states that use BEI testing, an associate degree combined with BEI Basic or Advanced certification may be sufficient to begin working. However, career advancement increasingly requires a four-year degree.

Bachelor’s degree programs: Four-year interpreting programs provide deeper training in linguistics, ethics, specialized interpreting settings (legal, medical, educational), and practicum experience. Programs at institutions like Gallaudet University, the National Technical Institute for the Deaf, and Western Oregon University are highly regarded.

Master’s degree programs: Graduate programs in interpreting are growing. A master’s degree is increasingly valued for specialized settings like conference interpreting, legal interpreting, and interpreter education. Gallaudet University and several other institutions offer master’s programs in interpretation.

Continuing education: Nearly all states with licensing requirements mandate ongoing continuing education. RID requires 8.0 CEUs (Continuing Education Units) per four-year certification cycle. Many states add their own continuing education requirements, sometimes including mandatory topics like ethics, Deaf culture, or specialized interpreting skills.

Steps to Get Certified

Here is a practical roadmap for navigating ASL certification requirements by state and building your interpreting career.

Step 1: Research your state. Visit your state’s commission for the deaf and hard of hearing website (or equivalent agency). Identify whether your state requires licensure, registration, or has no specific regulation. Note the specific credentials accepted, educational requirements, and any additional state-specific tests.

Step 2: Build your ASL fluency. Before you can interpret, you must be fluent in ASL. This takes years of study and, critically, immersion in the Deaf community. Take ASL courses, attend Deaf events, practice with Deaf friends and mentors, and seek out immersive experiences. Most interpreters study ASL for 4-6 years before achieving the fluency needed for professional interpreting.

Step 3: Complete an interpreter training program. Enroll in an accredited interpreter education program. The Commission on Collegiate Interpreter Education (CCIE) accredits bachelor’s-level programs. If your state accepts BEI, a two-year program may be sufficient to begin, but plan to continue your education.

Step 4: Gain supervised experience. Most interpreter education programs include practicum or internship components. Seek additional mentored experiences through organizations like RID’s Mentorship Program. Working under the guidance of experienced interpreters accelerates your skill development.

Step 5: Take the certification exam. Register for the NIC or BEI exam through the appropriate testing body. Prepare thoroughly — pass rates are not high, and most successful candidates invest in exam preparation courses and practice testing. Study groups with other aspiring interpreters can be invaluable.

Step 6: Apply for state credentials. Once you hold national certification, apply for your state license or registration. Complete any background checks, pay fees, and submit required documentation. Set reminders for renewal deadlines and continuing education requirements.
