Interpreter Certifications & State Requirements Updates 

When providing accommodations services to your stakeholders, it is key to utilize qualified and certified providers. Just as medical or legal professionals are required to maintain a series of active licenses and certifications to maintain their practices, ASL interpreters are also held to a strict standard of qualifications. With evolving framework nationwide, this article will explore national and state level certification standards for ASL interpreters and expand on the necessity of qualified partnerships between businesses and interpreting agencies.  

National-Level Certifications (RID & Others) 

RID and Its Certification System 

The RID (Registry of Interpreters for the Deaf), established in 1964, is the primary national governing body for American Sign Language Interpreters. RID describes this industry standardization as, “being certified helps to standardize practices and procedures within the sign language interpreting profession. The standardization promotes consistency and quality and helps to ensure that individuals working in the field are held accountable for their provision of services.” Certification with RID also includes annual recertification with varying requirements including CEU (Continuing Education Units) to maintain lifelong learning and skill development and testing.  

Using certified ASL interpreters rather than individuals who “just know ASL” is crucial for ensuring accurate, ethical, and culturally competent communication. Certification demonstrates that an interpreter has met rigorous national standards for language proficiency, interpreting skills, and professional conduct. While someone who knows ASL may be able to hold casual conversations, interpreting—especially in settings like medical appointments, legal proceedings, or educational environments—requires specialized training to accurately convey nuanced meaning, tone, and intent between English and ASL. Certified interpreters also follow a professional code of ethics, ensuring confidentiality, impartiality, and respect for all parties involved. Relying on uncertified individuals can lead to misunderstandings, incomplete information, or even serious legal and safety risks for Deaf and hearing participants alike. 

Requirements for RID Certification (NIC, CDI, etc.) 

Requirements for RID certification typically include a bachelor’s degree or equivalent in interpreting education, passed written and performance exams, and series of ongoing maintenance requirements. National certification provides interpreters with field recognition and eligibility for government, higher education, or other specialized assignments. RID certification drives the framework for most requests for proposals and bid invitations to vet participating agencies.  

The Northwest American Sign Language Associates, Inc. Outlines the following common certifications of sign language interpreters. While many of these certifications are no longer offered, they can still be found on resumes of many active interpreters.

State-Level Certification & Licensing 

Similar to state level professional legal or medical licenses or examinations, many states require licensure or certification for sign language interpreters, while others do not. Some focus on requirements for educational settings while others legislate varying fields. Many states have local RID chapters to connect local interpreters and manage state requirements. Additionally, many states have governing departments or commissions for services for the Deaf and hard-of-hearing who manage certification standards and maintenance. A full list of state requirements can be found at the RID state-by-state list, including state-unique certifications and licenses.  

Arizona:  

• Arizona Commission for the Deaf and Hard of Hearing www.acdhh.org/interpreters/ 

• Requires national certification in addition to ACDHH certification.

Typical State-Level Requirements 

Requirements to become a professional ASL interpreter may include earning an associate or bachelor’s degree in interpreting or a related field, passing state-specific certification exams such as the BEI or EIPA, and completing background checks, ethics training, and continuing education. According to ASLdeafined, some states offer streamlined paths to licensure. For example, the Iowa Department of Education accepts an EIPA score of 3.5 or higher or possession of the NIC for licensure by exam. These requirements ensure interpreters meet high standards of skill, professionalism, and ethical practice. 

State Requirements vs. National Certifications: A Comparative Table 

While easily perceived as extra hoops to jump through, these supplemental state-level requirements all exist to maintain interpreter integrity and protect the rights of Deaf and hard-of-hearing consumers. These additional checks and balances provided safeguards in a field that could easily go unnoticed or unchecked. ASL Deafined outlines these common variables between state and national level certifications in the visual below.  

Recommendations for Organizations Looking for ASL Providers 

Organizations seeking ASL providers should prioritize working with certified interpreters and reputable agencies to ensure both compliance with legal requirements and high-quality communication access. Before hiring, verify the interpreter’s credentials, such as state licensure, national certification (e.g., NIC, BEI), and recent continuing education. Partnering with established interpreting agencies can help streamline this process, as they typically handle credential verification, scheduling, and matching interpreters with assignments suited to their skill set. It’s also important to clearly communicate the setting, subject matter, and any specialized vocabulary in advance so the interpreter can prepare accordingly. Finally, build ongoing relationships with trusted providers—consistent collaboration fosters smoother communication, better cultural understanding, and more effective service delivery for Deaf and hard-of-hearing participants. 

In today’s evolving accessibility landscape, staying informed about interpreter certification and state requirements is essential for protecting the rights of Deaf and hard-of-hearing individuals while ensuring compliance with legal standards. Certified interpreters bring not only proven language and interpreting skills, but also a commitment to ethical conduct, confidentiality, and ongoing professional development. 

 Whether navigating national certifications like RID’s NIC or meeting state-specific licensure requirements, these qualifications safeguard the integrity of communication and reduce the risk of errors, misunderstandings, and legal liability. For organizations, partnering with qualified providers isn’t just a best practice—it’s a responsibility that upholds inclusivity, fosters trust, and ensures every interaction is as accurate and respectful as possible. By making interpreter credentials a priority, organizations demonstrate their commitment to meaningful and equitable access for all.
