Setting the Standard for Quality in Healthcare Interpreting

We administer a national, valid, credible, and vendor-neutral certification program for healthcare interpreters in the U.S.

CCHI is a national nonprofit organization founded in July 2009, operated as a 501(c)(6) corporation.

Our purpose is to develop and administer a comprehensive national interpreter certification program in order to assess medical interpreters’ competence and to help ensure quality of interpreting in any healthcare setting and in any modality of interpreting. CCHI brings together medical interpreters, representatives from national and regional non-profit interpreting associations, language companies, community-based organizations, educational institutions, healthcare providers, and advocates for individuals with limited English proficiency (LEP).

CCHI programs include the Core Certification Healthcare Interpreter™ (CoreCHI™) and Certified Healthcare Interpreter™ (CHI™) certifications for interpreters, and CEAP (Continuing Education Accreditation Program) for educators/trainers.

CCHI is the first and only organization certifying healthcare interpreters in the U.S. to receive NCCA accreditation for its certification programs.

CCHI is governed by elected volunteer Commissioners, many of whom are practicing medical interpreters and CCHI certificants. The Commissioners employ staff to manage operations and rate exams. CCHI contracts with a testing company and various testing sites across the U.S. to administer CCHI exams.
