No, interpreting (or translating a document) in itself or preparing for an interpreting assignment is not considered to be continuing education.
CCHI defines performance based (PB) training as training aimed to improve the healthcare interpreter’s skills in the three interpreting modes – consecutive, simultaneous and sight translation. PB courses must include instructor-led practice in those modes of interpreting (in-person or online). Online courses do not need to have a human instructor but must be structured in a way that allows the student to practice the three modes of interpreting and receive some feedback or model interpretation of assignments. The same applies to the online translation courses.
