Who it’s for
Built for the people taking this exam.
Patient care technicians, medical assistants, and cardiac monitor techs adding the CET credential to qualify for dedicated EKG roles, telemetry tech positions, or cath-lab support work.
Why it matters in 2026
The career signal.
CET is the most accessible cardiac-monitoring credential and a common employer requirement for telemetry technician and cardiac monitor tech roles. Adding CET to an MA or CNA credential meaningfully expands hireable positions and pay tiers, particularly in hospital telemetry units and outpatient cardiology where dedicated EKG roles still exist.
