If your TTT-1 or TTT-2 certification expires, there is no grace period. NWSA requires you to take the full exam again — the same 85- or 100-question test a first-time candidate takes, at the same $274 fee — to be recertified. The only way to avoid that is to recertify within the 12 months before your five-year certification expires, which is a shorter, single-exam process rather than starting over.
The rule is stated plainly in the current NWSA Candidate Handbook: "There is no grace period after certification has expired. Candidates whose certification has lapsed must take the full examination(s) to be certified again." That's worth reading twice if your expiration date is more than a year out and easy to forget about.
The window that matters: 12 months before expiration
NWSA's recertification process only exists inside a specific window: the 12 months before your certification's expiration date. Recertifying during that window requires:
- Passing the current recertification examination — the same primary exam in use at the time you recertify, not a shortened or different version
- Reaffirming compliance with NWSA's policies and procedures through the Attestation Statement
What "no grace period" actually means in practice
There's no day-30 or day-90 buffer after your expiration date where you're still considered current while you scramble to test. The day after expiration, your certification status is the same as someone who never held it — which means a carrier or GC checking your credentials at a gate sees an unqualified worker, not a lapsed one with an excuse. If your job depends on staying continuously credentialed, treat the 12-month recertification window as a hard deadline, not a soft target.

How your new five-year clock starts
This part surprises people: recertifying inside the 12-month window doesn't reset your clock from the date you passed the new exam. Instead, your new five-year period begins from the date your previous certification expired — so testing early inside the window doesn't cost you anything, and there's no benefit to waiting until the last possible week. Recertify at month 11 of the window or month 1, and either way your new certification runs five years from your old expiration date.
The one exception: if you recertify more than 12 months before your expiration date — which shouldn't normally happen, since NWSA's process is built around that window — your new certification period would begin immediately rather than from the old expiration date. For most candidates, the practical takeaway is simpler: test any time in that final year, and the math works out the same.
TTT-2 holders: one exam, not two
If you hold both TTT-1 and TTT-2, you don't need to separately recertify TTT-1. Passing the current TTT-2 recertification exam maintains both certifications. But there's a rule worth planning around: if you fail the TTT-2 recertification exam twice, NWSA requires you to take the full TTT-1 and TTT-2 exams again — both, from the start — to maintain either certification. That's a meaningfully bigger cost and time commitment than a single retake, so don't treat a first failed recertification attempt casually. For the full comparison of how the two levels' renewal rules interact, see TTT-1 vs TTT-2: the difference explained.
If you fail (recertification or first attempt)
Whether it's your first TTT-1 attempt or a recertification exam, the retake rules are the same: a minimum 30-day wait between attempts, a new application, and paying the exam fee again — $274 each time. You'll also receive a strength-and-weakness report by content domain after a failed attempt, which is the most useful thing to study from before you retest.

What to do before your window opens
The cheapest fix for this entire problem is a calendar reminder, not a study plan. Mark your certification's five-year expiration date, then set a reminder 12 months before it — that's the day your recertification window opens, and the day it makes sense to start planning your exam date rather than the day you're forced to. For what's actually tested (the recertification exam is the same primary exam as a first-time candidate's, so the content hasn't changed even if you're a veteran), see TTT-1 exam: what's on it and how to study for it.
Our TTT-1 Exam Prep course works the same whether you're preparing for a first attempt or a recertification exam — the five domains and question style don't change. It isn't affiliated with or endorsed by NWSA and doesn't itself certify or recertify you.
Why tracking this matters more than tracking a lot of certifications
TTT-1 and TTT-2 are unusual among the credentials a tower tech typically holds in exactly one respect: most safety-awareness cards (OSHA 10, first aid/CPR, RF awareness) either don't expire or renew on a simple annual or biennial cycle with grace built in. TTT-1 and TTT-2 don't work that way — a hard five-year cliff with zero grace period, and a renewal window that opens a full year before the deadline. That combination (long validity, hard cutoff, early window) means it's exactly the kind of date that's easy to lose track of precisely because five years feels distant when you first pass, and exactly the one that costs the most — a full re-exam and fee — if you do.
What this means for employers tracking a roster
If you manage a crew rather than just your own certification, the same principle scales up: a roster spreadsheet that tracks hire date and job title but not certification expiration dates will eventually put a lapsed TTT-1 or TTT-2 holder on a job site without anyone noticing until a carrier audit catches it. Building expiration tracking into standard roster management — not a separate, easy-to-forget process — is the difference between catching a recertification window with months to spare and discovering a lapse the morning of a site audit.
Frequently asked questions
Is there any grace period at all after TTT-1 or TTT-2 expires?
No. NWSA's handbook states plainly that there is no grace period, and a lapsed certification requires the full exam to be recertified.
If I recertify early in my 12-month window, do I lose time off my new certification?
No. Recertifying anywhere within that 12-month window means your new five-year period starts from your old expiration date, not from the date you actually tested.
Does recertifying TTT-2 also renew TTT-1?
Yes, as long as you already hold both. Passing the current TTT-2 recertification exam maintains both certifications together — you don't test TTT-1 separately.
What happens if I fail my TTT-2 recertification exam twice?
You're required to take the full TTT-1 and TTT-2 exams again — both, from the beginning — to maintain either certification. This is a materially bigger commitment than a normal retake.
