Radiologic technologists renew their credential on a two-year cycle tied to their birth month, not the calendar year. That detail catches many technologists off guard each renewal season, since the deadline never lands on the same date twice.

How to maintain ARRT certification with CE credits comes down to two habits: knowing the exact deadline and logging hours as they happen. Waiting until the final weeks of a biennium to count credits causes most renewal problems.

Why Last-Minute Tracking Falls Short

Technologists who wait until the deadline often find gaps in their own records. A course finished months earlier may never have been logged, or a certificate may be missing entirely. Reconstructing that history under time pressure adds stress to an already full work schedule.

Category A and Category A+ credits follow separate rules, and mixing them up can leave a technologist short at the worst possible moment. A structured tracking habit avoids that scramble entirely.

What the Numbers Show

According to ARRT, technologists must complete 24 credits of approved continuing education every two years, or 50 credits for R.R.A. certificants. Sonography certificants need 16 of those 24 credits in their specific discipline.

the American Society of Radiologic Technologists's 2025 staffing survey found computed tomography vacancy rates climbed to 19.4 percent, the highest level on record. Departments already short-staffed have less room to cover a technologist sidelined by a lapsed credential.

Building the Habit Into a Normal Month

Spreading credit collection across the full biennium removes the year-end scramble. A technologist who completes two or three courses each quarter finishes with room to spare well before the deadline. Short online courses fit into a lunch break, which makes the quarterly habit easier to keep than a single marathon session.

  • Log each completed course into a single tracker the same week it happens, including the certificate number and date.
  • Review the remaining credit balance every three months instead of waiting for a renewal notice.

Final Thoughts

Certification lapses rarely happen because a technologist stopped caring about the work. They happen because tracking fell behind during a busy stretch, and a missed deadline is far harder to fix after the fact than a single skipped quarter.

How to maintain ARRT certification with CE credits is ultimately a scheduling habit more than a knowledge problem. A technologist who checks progress every few months rarely faces a last-minute deadline.
