Whether you’re hiring an interpreter for the first time or replacing an unreliable vendor, the goal is simple:
Make sure you select an interpreting agency that delivers accuracy, professionalism and reliability every single time.
Why Selecting the Right Sign Language Interpreting Agency Matters
Poor interpreting doesn’t just create inconvenience. It leads to:
- Miscommunication in medical settings
- Legal and compliance issues (ADA, Section 504, Section 1557)
- Patient dissatisfaction and lower care quality
- Lost productivity in government or business environments
- Classroom confusion and lower student engagement
A qualified, dependable interpreting agency solves these issues before they happen.
Key Factors to Look for When Hiring a Sign Language Interpreting Agency
Below are the criteria organizations most often search for online, such as “best ASL agency near me,” “how to hire interpreters,” “top sign language services,” and “ADA-compliant interpreting.” Each factor includes practical questions to ask and real-world considerations that help you choose with confidence.
1. Interpreter Qualifications and Certifications
An agency should provide interpreters who are professionally credentialed and not hobbyists, relatives or well-meaning volunteers.
What to Look For
- RID-certified interpreters (NIC, CI/CT, CDI, etc.)
- State-qualified interpreters meeting local licensing requirements
- Specialty-trained interpreters for medical, legal, mental health or educational settings
- Experienced CDIs (Certified Deaf Interpreters) for high-complexity cases
Questions to Ask
- “What percentage of your interpreters hold national certification?”
- “Do you provide specialty-trained interpreters for medical or legal appointments?”
2. Reliability, Availability and Fill-Rate
If you’ve ever wondered,”Why does my current agency keep canceling on me?” It’s usually because they lack staffing depth or efficient dispatch systems.
What to Look For
- High fulfillment rates (industry-leading agencies exceed 95%)
- 24/7 or extended-hours scheduling
- Ability to cover same-day or emergency requests
- A real human scheduler and not an automated voicemail pit
Questions to Ask
- “What is your average fill rate for medical appointments?”
- “How do you ensure coverage during weekends, nights, or holidays?”
3. Compliance, Documentation and Liability Protection
For healthcare systems, school districts, and government agencies, compliance is non-negotiable.
What to Look For
- HIPAA-trained interpreters
- Background checks, Level II fingerprinting (where required)
- Clear liability insurance and professional indemnity coverage
- ADA and Section 1557 compliance support
Questions to Ask
- “Do your interpreters receive HIPAA training yearly?”
- “Can you provide documentation for audits or compliance reviews?”
4. Industry Expertise and Specialization
Not all interpreting assignments are equal. A classroom interpreter is not interchangeable with a trauma-room interpreter or a courtroom interpreter.
Examples of Specialty Needs
- Hospitals: ER, surgery, OB, oncology, discharge instructions
- Schools: K–12 mainstreaming, IEP meetings, college lectures
- Legal: Attorney-client meetings, hearings, depositions
- Business: Conferences, HR meetings, customer service interactions
Questions to Ask
- “Do you assign interpreters based on skill match or simply availability?”
- “Can you provide CDIs for complex or nuanced communication?”
5. Technology, Scheduling Tools and Communication
Agencies that invest in technology provide faster service and fewer headaches.
What to Look For
- Secure online scheduling portals
- Real-time confirmation and communication
- VRI (Video Remote Interpreting) options for backup or overflow
- Automated reminders and appointment logs
Questions to Ask
- “Do you offer both on-site ASL and VRI interpreting?”
- “What tools do staff use to track and manage interpreter requests?”
6. Customer Service and Responsiveness
A great agency makes scheduling feel effortless, not frustrating.
Look for Agencies That:
- Respond within minutes and not hours
- Learn your facility’s preferences
- Assign familiar interpreters for repeat appointments
- Offer dedicated account managers
Questions to Ask
- “How fast does your team respond to urgent requests?”
- “Will we have a single point of contact for scheduling?”
7. Reputation, Reviews and Track Record
Many organizations compare agencies by searching “best sign language interpreting companies,” “top ASL agencies in my area,” or “trusted ASL service providers.”
What to Look For
- Proven relationships with hospitals, schools, and government agencies
- Testimonials and case studies
- Several years of service in the community
- Positive Deaf community feedback
Questions to Ask
- “What organizations similar to ours do you currently serve?”
- “Can you share references from healthcare or education clients?”
