Become a Sign Language Interpreter: A Practical Path in the US
How to become a sign language interpreter in the US: building ASL fluency, interpreter training, certification, specializations, and setting up a camera for remote interpreting work.
The short answer
To become a sign language interpreter in the US, you need fluency in American Sign Language (ASL) and English, formal training in interpreting between them, supervised practice, and usually a recognized credential. Knowing how to sign is not the same as being able to interpret. Interpreting means conveying meaning accurately and in real time between two languages and cultures, often under pressure and while following a professional code of conduct.
Two points can change what this answer means for you. First, "sign language" in the US usually means ASL. ASL is a full language with its own grammar, not signed English. Other countries use different sign languages and set their own credential rules, so this guide applies only to the US. Second, requirements vary by state and by work setting. Before committing to a path, check the rules where you plan to work.
Step-by-step path
- 1. Learn ASL as a language. Take structured courses through a college, community program, or qualified Deaf instructors, and aim for real fluency rather than vocabulary alone.
- 2. Spend time in the Deaf community. Attend Deaf events and social gatherings, and keep using ASL with fluent signers. This builds conversational skill and an understanding of Deaf culture, both of which interpreting depends on.
- 3. Complete an interpreter education program. These programs, sometimes called interpreter training programs, are offered at the associate and bachelor's level. They teach interpreting technique, ethics, and practice in different settings.
- 4. Get supervised experience. Use mentorships, internships, and practicum placements to work under the guidance of experienced interpreters.
- 5. Earn a credential. The Registry of Interpreters for the Deaf (RID) offers national certification. Some states run their own systems, and Texas, for example, uses the Board for Evaluation of Interpreters (BEI). Educational interpreters in K-12 schools are often assessed with the Educational Interpreter Performance Assessment (EIPA). Confirm which credential applies in your state and setting, along with its current eligibility rules.
- 6. Check state licensure. Some states require a license or registration to work as an interpreter. Others do not.
- 7. Keep your skills current. Certified interpreters generally must complete continuing education to keep their credentials active.
How to check your progress
- Ask fluent Deaf signers and working interpreters for feedback. Self-assessment alone tends to overestimate your skill.
- Record your practice interpretations and compare them with the source message. Look for omissions, additions, and shifts in meaning.
- Review the official candidate handbook for the credential you are targeting, so you know exactly what the exam covers and what you must have before applying.
Specializations to know about
Interpreters work in educational, medical, legal, community, and performing-arts settings, and each can carry extra requirements. Legal and medical work in particular usually calls for added training or specialized credentials. Deaf interpreters are another route. They are Deaf professionals who work alongside hearing interpreters or with Deaf clients whose communication needs call for that expertise, and RID has offered a separate credential for this role.
If you plan to interpret remotely
Much interpreting now happens over video, through video relay services (VRS) for phone calls and video remote interpreting (VRI) for meetings and appointments. Employers and platforms set their own technical standards. The general principles below help make signing clear on camera.
- Framing: keep your full signing space in view, from above your head to below your waist and out to both elbows, so that no handshapes or movements are cut off.
- Background: a plain physical background in a solid color that contrasts with your skin tone makes hands easier to read. Virtual or blurred call effects can smear or clip fast hand movements, so a real plain background is usually more reliable.
- Clothing: solid colors that contrast with your skin usually work better than patterns.
- Lighting: light your face and hands evenly from the front, and avoid a bright window behind you, which turns you into a silhouette.
- Verification: a camera that has permission in the browser or operating system is not guaranteed to show a usable picture. Run a test recording or a test call to confirm the image appears and that motion stays clear. Separately confirm that the microphone picks up the hearing party's speech clearly, not just that the device is detected.
