(OKLAHOMA CITY, OKLAHOMA) The Federal Aviation Administration is racing to rebuild its controller ranks after the recent government shutdown, but officials say the most basic figure remains unclear: how many air traffic controllers must retrain before they can return to full duty. As of November 2025, no agency tally has been released, even as towers and radar rooms juggle schedules, bring in temporary help, and stretch supervisors to keep flights moving. The picture is complicated by a broader shortfall and an uneven training pipeline that was stressed long before the stoppage.
Staffing shortfall and retraining uncertainty

FAA workforce planners say the system is running with a gap of about 3,000 certified controllers compared with target staffing. That deficit was worsened by a spike in retirements and resignations tied to the shutdown.
Controllers who left the boards for weeks may now need recertification steps at their facilities, but the agency hasn’t said how many will go through that process. The absence of a national figure reflects different requirements across facility types:
- Tower, TRACON, and en‑route centers have local certifications.
- Skill sets and proficiency checks vary by position and airspace complexity.
- Decisions are made locally, so a single nationwide count is hard to produce.
Training pipeline and the FAA Academy
At the FAA Academy in Oklahoma City, new hires continued to graduate during the stoppage — an important break from 2019 when the academy went dark. Even so, several early training steps that rely on funding were delayed.
- Onboarding and specialized lab time saw interruptions.
- Some trainees entered facilities and began on‑the‑job training without pay, a situation unions and managers say added stress.
- The agency attempted to protect critical classes, but the shutdown slowed the steady flow the pipeline needs to rebuild a stable workforce.
Field responses and operational workarounds
In the field, managers used multiple temporary measures to keep traffic moving:
- Brought in military controllers to fill gaps at select locations.
- Reassigned some supervisory staff back onto the boards.
- Tapped recently retired controllers willing to return.
- Accelerated trainees forward where safe and feasible.
These measures helped maintain operations but also produced mismatches. Facilities borrowed staff temporarily while awaiting local certifications, making it harder to predict how many returning controllers will require additional practice, checks, or full retraining.
Pressure from departures and instructor shortages
The retirement wave is the biggest pressure point. Agency data show departures rose from roughly four per day to as many as 15–20 per day during the shutdown window, as eligible controllers opted for stability.
- Such attrition erases years of investment in weeks.
- Each new controller requires substantial live oversight from certified instructors.
- When instructors are pulled for operational coverage, the training pipeline slows further, creating a reinforcing loop that will take time to break.
What travelers might notice
Practical impacts are uneven across the system:
- Busy hubs have prioritized staffing and adjusted schedules to cover peak periods.
- Smaller facilities sometimes lean on overtime or loaned staff.
- Controllers returning after weeks off must meet local rules requiring proficiency checks or, in some cases, structured refresher training.
However, the total number of controllers needing retraining or checks has not been disclosed. The FAA’s national focus is on restoring capacity safely, while each facility determines local sign‑offs before full duty resumes.
Agency response and recovery outlook
Transportation Secretary Sean Duffy has urged a faster push at the academy, emphasizing “supercharging” training to increase graduate numbers. That can help the long‑term shortage but does not immediately answer how many incumbents must retrain after time away.
Key factors that determine retraining needs include:
- Length of absence from live traffic.
- Complexity of the facility and sector-specific requirements.
- Whether airspace changes occurred during the shutdown.
The FAA says it will keep classes moving in Oklahoma City and at field facilities while balancing safety and speed. According to analysis by VisaVerge.com, the combination of an existing shortage, the shutdown’s pause, and higher attrition means recovery will take time, even with accelerated efforts.
The system can surge temporarily, but sustainable staffing requires a steady inflow of trainees and consistent mentoring.
Human impacts and training delays
For families of controllers, this period has meant long hours, changing shifts, and uncertainty about when routines will normalize. Specific human impacts include:
- New hires expecting paid training starting in limbo, beginning on‑the‑job learning without pay until funding was restored.
- Trainees losing momentum when instructors were pulled for operational coverage.
- Each delay adding days to certification timelines and postponing when a trainee becomes fully operational.
These are not just statistics — they reflect real stress on people and on the system’s ability to rebuild capacity.
Safety standards and local determinations
Officials emphasize that safety rules are not changing. Returning controllers must meet existing proficiency standards at their facility, with local examiners verifying required skills for each sector or runway configuration.
- If the time away from live traffic was long, retraining can be extensive.
- If the absence was brief, a check ride may suffice.
- Decisions are made one person at a time, explaining why no single national number is available.
Transparency and next steps
The FAA has signaled more transparency on hiring targets and academy throughput, though it has not promised a facility‑by‑facility breakdown of retraining figures.
Current agency efforts highlighted by officials include:
- Keeping simulation bays staffed.
- Boosting instructor capacity.
- Protecting critical gate checks that mark trainee progress.

What remains certain: the system needs more certified air traffic controllers, and the training pipeline must stay steady to restore capacity — even as the exact retraining count after the shutdown remains not publicly available.
This Article in a Nutshell
The FAA is addressing a worsened controller shortage—about 3,000 below targets—after the 2025 shutdown, which prompted higher retirements and resignations. Local facilities set varied recertification rules, so no national tally exists for controllers needing retraining. The FAA Academy kept some classes running but saw funding-related delays and unpaid on‑the‑job training. Field workarounds—military staff, retirees, and reassigned supervisors—kept operations going but stressed instructor availability. Recovery requires sustained training throughput and time, even with efforts to accelerate academy output.
