CoreCHI · Work through your exam, one topic at a time.
CoreCHI™ (Core Certification Healthcare Interpreter™) is a knowledge-based credential from CCHI, the Certification Commission for Healthcare Interpreters, designed to measure the core professional knowledge that a medical interpreter needs regardless of the language pair they work in.
