EHCI Learning & Certification

Competency framework

See what each credential level is intended to measure, the evidence used, and the claims it does not support.

A trustworthy skills credential separates learning outcomes, assessment evidence and claim limits. This framework describes the current EHCI model; published course details remain the source for available training and assessment settings.
