Top ASL Certifications to Pursue in 2025

When it comes to working as an ASL interpreter, having nationally recognized credentials is essential. Here are the best certifications for 2025. 

1. RID Certifications (Registry of Interpreters for the Deaf)  

The Registry of Interpreters for the Deaf (RID) offers some of the most comprehensive certifications in the field.  

  • CSC (Comprehensive Skills Certificate): Though no longer issued, holding this certificate indicates qualifications in both interpreting and transliteration skills.  
  • CI/CT (Certificate of Interpretation and Certificate of Transliteration): These separate yet complementary certifications validate skills in conveying spoken English into ASL and vice versa.  
  • NIC (National Interpreter Certification): A widely accepted credential, the NIC evaluates interpreting skills, ethical decision-making, and professionalism.  
  • CDI (Certified Deaf Interpreter): Designed for deaf interpreters, this certification focuses on cultural competency as well as interpreting skills.  

2. BEI Advanced Certification  

The Board for Evaluation of Interpreters (BEI) offers certifications for interpreters in specific states and regions. Their Advanced level ensures interpreters have mastered complex communication scenarios and are prepared to adjust their interpretation based on diverse audience needs.  

3. NAD Certification (Level 4 and Above)  

The National Association of the Deaf (NAD) certification is recognized for supporting interpreters who work within the Deaf community. A Level 4 or above indicates strong skills and competencies, making participants highly sought after in a variety of settings.  

Top Spoken Medical Interpreter Certifications in 2025  

Spoken medical interpreters serve as essential communicators between medical professionals and patients with limited English proficiency or communication barriers. Here are the most recognized certifications to consider for this niche.  

1. CCHI Certification (Certification Commission for Healthcare Interpreters) 

The CCHI offers two respected certifications tailored to healthcare interpreting professionals:  

  • CoreCHI: Focused on validating core competencies in professional conduct, cultural responsiveness, and interpreting protocols. It doesn’t require a language proficiency exam.  
  • CHI (Certified Healthcare Interpreter): Includes a language proficiency test and offers specialization for Spanish, Mandarin, and Arabic interpreters.  

2. NBCMI Certification (National Board of Certification for Medical Interpreters)  

The NBCMI is well-regarded in the healthcare industry. Its certification programs include:  

  • CMI (Certified Medical Interpreter): Specialization in languages such as Mandarin, Cantonese, Russian, and others.  
  • Hub-CMI: For interpreters who want a core credential, this certification doesn’t yet include a language proficiency test.  

3. 40-Hour Medical Interpreter Training  

This foundational training is often a prerequisite for higher credentials like CCHI and NBCMI. Many employers view this as a basic qualification for entry into medical interpreting.
