1.2 Eligibility, Application, and Scheduling

The two eligibility pathways

NHA requires every CET candidate to hold a high school diploma or GED/equivalency (or expect to earn it within the next 18 months) and to qualify through one of two pathways. Confirm your pathway before you pay, because the fee is non-refundable and an unverifiable application stalls scheduling.

The ten live EKGs are an easy requirement to overlook. They must be performed on real individuals (not manikins or simulations), and you must be able to provide evidence of them. If you self-trained or your program lapsed, the experience pathway is the fallback, but it demands verifiable supervised hours.

A clean application sequence

Most CET failures that have nothing to do with EKG knowledge are administrative. Follow this order:

• Confirm which pathway you meet and gather the supporting documents.
• Create or update your NHA candidate account.
• Submit the application and pay the $134 fee.
• Receive authorization, then select delivery (school, PSI center, or live remote proctoring).
• Schedule only when your practice scores are consistently above the equivalent of the 390 cut.
• Save the confirmation, ID requirements, and exam-day instructions.

If you test at your own training program, the school often handles authorization and scheduling for you; independent candidates schedule directly through NHA and PSI.

Remote proctoring and ID rules

Live remote proctoring lets you test from home, but it imposes strict conditions: a quiet, private room; a working webcam and microphone; a clear desk; and a government-issued photo ID whose name matches your application exactly. A name mismatch (a maiden name on the ID versus a married name on the account, for example) is a frequent same-day disqualifier. The proctor scans the room before launch, and leaving the camera frame can void the session. PSI test centers apply the same ID standard with on-site check-in.

Retake and waiting-period logic

If you do not pass, NHA requires you to wait at least 30 days before you sit again. You get three attempts; after a third failed attempt, you must wait one year before each further attempt. The practical rule: do not schedule a retake reflexively. Use the per-domain bands from your score report to repair the specific weak domain, re-test your readiness with timed mixed practice, and only then rebook. Each attempt carries the full exam fee, so a rushed retake is expensive twice over — once in money and once in a used attempt.

Build your study calendar backward from a realistic appointment date, leaving the final two weeks for timed mixed practice rather than first-time learning.

Documenting the ten live EKGs

The ten-EKG requirement is concrete and verifiable. NHA expects evidence that you personally performed at least ten EKGs on live individuals — meaning real patients or volunteers, not training manikins, simulators, or screen-based practice. At registration you attest that you meet the eligibility requirements, so keep the documentation (for example, your program's skills log) where you can produce it.

Self-prep candidates and those whose program lapsed must assemble this proof themselves through the experience pathway, which is harder, because it requires a supervisor to verify hours.

The practical lesson: confirm before paying that your documentation chain is complete. A candidate who pays the fee, studies for six weeks, then discovers the program never logged the tenth live EKG cannot sit until the gap is closed, and the fee does not refund itself.

What a delayed application looks like

The through-line across all four rows is the same: the knowledge part of the CET is only half the battle, and the administrative half can stop an attempt before it starts. Treat eligibility verification as a hard gate you clear before a single timed practice set.
