Pool 1 vs Pool 2: FAA ATC Trainee Applicant Pools

Pool 1 is for graduates of FAA Collegiate Training Initiative (CTI) programs who have an endorsement letter, veterans eligible for a Veterans Recruitment Appointment, and veterans with military aviation experience or veterans' preference. Pool 2 is every other eligible U.S. citizen. You choose one pool when you apply. Under federal law, Pool 1 applicants get preferential consideration before Pool 2 within each ATSA qualification category. The pool doesn't change your ATSA result, the minimum qualifications or the age limit.

Who belongs in Pool 1

The April 2026 trainee announcement (FAA-ATO-26-ALLSRCE-97350) lists three ways to qualify for Pool 1, each needing documentation:

1. CTI graduate: You graduated from an FAA Collegiate Training Initiative program and have an official CTI endorsement letter. The letter must be on CTI school letterhead, signed by the program's point of contact, and confirm you completed all CTI program requirements. The announcement notes the letter "is not a personal recommendation." You also submit transcripts showing your degree conferral date.
2. VRA-eligible veteran: You qualify for a Veterans Recruitment Appointment under Title 38.
3. Veteran with aviation experience: You're a qualifying veteran with aviation experience from military service, and/or you're eligible for veterans' preference under 5 U.S.C. 2108.

For veterans, the documents are typically a DD-214 (or certification of expected honorable discharge), plus a VA letter and SF-15 if claiming 10-point preference. Check the Required Documents section of the announcement you're applying to — a missing document can cost you Pool 1 eligibility.

Graduating soon? The 2026 announcement let spring 2026 CTI graduates submit current transcripts at application and provide final transcripts and the endorsement letter before any firm offer. Earlier announcements had similar exceptions for that season's graduates.

Who belongs in Pool 2

Pool 2 covers all U.S. citizens who don't meet the Pool 1 criteria, plus Pool 1-eligible applicants who choose Pool 2 instead. The federal statute describes Pool 2 applicants as individuals applying under an announcement "recruiting from all United States citizens."

Pool 2 applicants still need to meet one of the five ways to qualify. In 2026, those were one year of general work experience (about 2,080 hours, including part-time and volunteer work), a bachelor's degree, a combination of education and work, air traffic control experience, or certain other aviation experience such as an instrument rating.

How the pools affect selection

The pools come from 49 U.S.C. 44506(f). The statute sets a clear order:

1. Experienced controllers first. The FAA must give preferential consideration to people with at least 52 consecutive weeks of qualifying air traffic control experience within five years. They're usually hired through separate announcements and, according to the DOT Inspector General, don't take the ATSA.
2. Then, within each ATSA category, Pool 1 before Pool 2. The law says the FAA gives "further preferential consideration, within each qualification category based upon pre-employment testing results (including application of veterans' preference ...), to pool 1 applicants ... before pool 2 applicants."

Read plainly, your ATSA category comes first, and the pool sets the order within that category. Choosing Pool 1 doesn't move you into a higher category, and it doesn't help if your result is in a category the FAA isn't selecting from. In the 2025 and 2026 announcements, only Best or Well-Qualified results were considered. See ATSA score bands.

The FAA doesn't publish exactly how it builds referral lists from these rules, how many selections come from each pool, or how preference interacts with ranking in detail. We didn't find pool-level selection statistics in the FAA, USAJOBS or Inspector General sources we reviewed, so be skeptical of confident claims about Pool 1 "odds."

Choosing a pool

You can pick Pool 1 or Pool 2, but not both. A few practical points:

• If you clearly qualify for Pool 1 and have the documents, it's generally the stronger choice, because of the statutory order within each category.
• If you pick Pool 1 and are found ineligible, recent announcements say you'll automatically be considered in Pool 2, provided you meet one of the five ways to qualify. The February 2025 announcement put it this way: "If you elect Pool 1, and it is determined that you do not meet Pool 1 eligibility, you will automatically be considered under Pool 2 eligibility requirements." The 2026 version keeps that fallback. We didn't find that sentence in the 2023 or 2024 announcements.
• If you change anything in your application before the announcement closes, resubmit it. Announcements warn that unsubmitted changes aren't considered.

How the pool rules have changed, 2023–2026

Announcement	Pool 1 criteria	Other notable changes
FAA-ATO-23-ALLSRCE-84315 (May 2023)	CTI graduates with an endorsement letter; VRA-eligible veterans; veterans with military aviation experience or preference. Veterans had to provide a Certificate of Release or Discharge within 120 days of the closing date.	Work-experience route required three years of full-time, progressively responsible experience. May 2023 CTI graduates could submit the endorsement letter later.
FAA-ATO-24-ALLSRCE-88674 (April 2024)	Same three criteria and 120-day discharge documentation wording.	Same three-year experience route; spring 2024 graduate exception.
FAA-ATO-24-ALLSRCE-92381 (Oct–Nov 2024)	Same three criteria.	Work-experience route cut to one year of full-time work, part-time pro-rated. Clarified that the endorsement letter is not a personal recommendation.
FAA-ATO-25-ALLSRCE-94224 (Feb–Mar 2025)	Same three criteria, now pointing applicants to the Required Documents section and to OPM's VRA guidance.	Added the automatic fallback from Pool 1 to Pool 2. Stated the FAA was selecting from Best and Well Qualified, prioritizing Best Qualified.
FAA-ATO-26-ALLSRCE-97350 (April 2026)	Same three criteria in plain-language format, with detailed endorsement letter requirements.	Kept the fallback. Required a Best or Well-Qualified ATSA result.

The underlying pool definitions haven't changed in this period. What has changed is how clearly the announcements explain them and what happens if you choose the wrong pool.

Pool 1 isn't the same as Enhanced CTI

Graduates of the smaller group of Enhanced AT-CTI programs have had a separate path. The FAA's Enhanced CTI direct-hire public notice (FAA-ATO-26-PUBNOT-96438, open October 3, 2025 to October 2, 2026) is limited to Enhanced CTI graduates or students within 12 months of graduation. It requires a well-qualified ATSA result, and the notice says successful graduates are placed directly at air traffic facilities to begin on-the-job training. Regular CTI graduates apply through the general trainee announcements, where CTI status places them in Pool 1. See our guide to the Enhanced AT-CTI program.

What stays the same for both pools

• You must be a U.S. citizen and under 31 on the announcement closing date, with narrow exceptions for people previously hired into FAA or Department of Defense civilian controller positions before 31. See the age limit guide.
• You must take the ATSA when invited, unless you have a valid previous result, and your most recent result is used.
• If selected, you need medical clearance (including a psychological assessment and drug test) and a background investigation. See the tentative offer letter guide.

Since the pool only matters within a category, your ATSA result is the part you can most directly work on. Short demos like ATC Simulation and Work Style show how practice sections are built, and full access is on the pricing page. This is familiarization, not a copy of the real test.

Frequently asked questions

Are Pool 1 applicants more likely to be hired?

They get preferential consideration within each ATSA category, which is an advantage over Pool 2 applicants in the same category. But the FAA doesn't publish selection rates by pool, and a Pool 1 applicant with a result in a category the FAA isn't selecting from won't be moved ahead.

Can I apply in both Pool 1 and Pool 2?

No. Announcements say you can choose Pool 1 or Pool 2, but not both. Recent announcements automatically consider ineligible Pool 1 applicants in Pool 2 if they meet the basic qualifications.

Do Pool 1 applicants still have to take the ATSA?

Yes. CTI graduates and veterans on trainee announcements still need an ATSA result in the categories being selected.

Does Pool 1 change the age limit?

No. The under-31 requirement in the trainee announcements applies to both pools. Federal law allows a higher maximum entry age of 35 only for applicants with qualifying air traffic control experience, which is a separate route.
