TTT-1 (Telecommunications Tower Technician 1) is a certification issued by the National Wireless Safety Alliance (NWSA). To get it, you set up a profile in the NWSA candidate portal, pay $274, and pass one written exam: 85 multiple-choice questions in 90 minutes, taken online with a live remote proctor. Since January 1, 2024 there is no practical test. The certification is good for five years, and you renew it by passing the current TTT-1 exam in the 12 months before it expires.
That's all there is to it. The trouble is that a lot of what's still online about TTT-1 was written for the old version of the program, so it lists steps that aren't required anymore. Here is the current process, based on the NWSA Candidate Handbook (Rev 10/25), plus a few mistakes that cost people money.
What TTT-1 actually says about you
NWSA defines a TTT-1 as "an individual who can safely perform tasks on telecommunication sites under direct supervision." The key words are under direct supervision. TTT-1 doesn't make you a lead. It shows that a hand working on a tower crew knows the safety and job basics that NWSA tests.
TTT-2 is the next step up: someone who can do the work and also supervise TTT-1 technicians and trainees. You have to hold TTT-1 before you can apply for TTT-2. After TTT-2 come the specialty certifications (Antenna and Line, Advanced Rigging Concepts) and Foreman, and each of those requires TTT-2.
A few facts about the credential that you might need when talking with an employer:
- NWSA is an independent nonprofit founded in 2015. Its TTT-1 and TTT-2 programs are accredited by ANSI under ISO 17024, the standard for bodies that certify people.
- NWSA doesn't train anyone. Its handbook says it "does not conduct training, nor does it provide training materials." That keeps the exam separate from any school, including ours. It also means that any course, ours included, gets you ready for the exam. None of them give you the certification.
- You get a digital credential. It shows up in your candidate profile right after you pass, and an employer can verify it.
Requirements: shorter than you've been told
Under the current handbook, a TTT-1 candidate has to do two things:
That's the whole list. If a site tells you TTT-1 needs a hands-on climbing test, a physical-capability sign-off, a First Aid/CPR card or OSHA 10 first, it's describing an older version of the program or a particular training company's package. NWSA ended its TTT practical exams on January 1, 2024. In June 2025 it handed that practical program to NATE, which now uses it as training material instead of a certification test.
Your employer or the site owner can still require first aid, OSHA 10, RF awareness, or a competent climber designation. Those are their rules, though, not NWSA's. Keep the two lists apart.
What it costs
The TTT-1 exam fee is $274, taken via online remote proctoring. The handbook also lists two smaller fees: $35 for a replacement certification card and $30 if you change anything after you've submitted your application.
A retake costs the full fee again. If you fail, you have to wait at least 30 days, reapply and pay again. That's why the application rules below matter more than they look.
Prep is up to you. You can study on your own, get training from your employer, or take a third-party course. NWSA lists all of those as valid ways to prepare. Our TTT-1 Exam Prep course costs $100 and takes about 9 hours online. We explain what's in it further down.

The rules that eat people's $274
The six-month clock. You have six months from the day you pay to take the exam. After that, the application expires and the fee is gone. Applications also can't be refunded, transferred or cancelled. Don't pay in January for an exam you'll "get around to" in the fall.
Don't pay in January for an exam you'll "get around to" in the fall.
Showing up late. If you're 59 minutes late or miss the appointment, you lose the fee. The same goes if your pre-check fails on exam day and you don't reschedule at least 30 minutes before the start. The handbook says to reschedule when a check fails, not to try it anyway.
Your ID. It has to be current, government-issued and have a photo and date of birth. If you don't have one on exam day, you don't test.
Missing your renewal. There's no grace period. If your certification lapses, you take the full exam again as if you'd never been certified.
Renewal: every five years, one exam
TTT-1 is valid for five years. To renew, you pass the TTT-1 exam that's current at the time and re-sign the attestation, all within the 12 months before your expiration date. If you renew inside that window, your new five-year term starts from your old expiration date, so testing early in the window doesn't cost you anything. If you renew more than 12 months early, the new term starts right away and you lose the time you had left.
If you move up to TTT-2, the TTT-2 recertification exam keeps both TTT-1 and TTT-2 current.
Where TIRAP fits
TIRAP, the Telecommunications Industry Registered Apprenticeship Program, is a U.S. Department of Labor–registered apprenticeship. Its national sponsor is the Wireless Infrastructure Association (WIA). It's an apprenticeship run by employers, with its own tower technician occupations and levels. It isn't the NWSA exam and it doesn't replace it. If you're in a TIRAP apprenticeship, ask your sponsor whether and when NWSA exams are part of your path. If you aren't, you can still take the TTT-1 exam directly.
Getting ready without guessing
The official exam outline breaks TTT-1 into five domains: job planning and logistics, fall protection and rescue, hoisting and rigging, structures, and appurtenance installation. Fall protection alone is about 30% of the exam. The full breakdown, with sample questions and a study plan, is in TTT-1 exam: what's on it and how to study for it.
If you'd rather follow a structured course than piece it together from standards, our TTT-1 Exam Prep follows those five domains in 34 lessons and ends with a 90-question practice test. The questions are original, not copied from the real exam. You need 80% to pass the practice test, and you can retake it. Two things it isn't: it isn't affiliated with or endorsed by NWSA, and it doesn't make you TTT-1 certified. Only passing NWSA's exam does that. What you get from us is a certificate of completion for the prep work, plus a clear idea of whether you're ready before you pay $274.
Once you have your credential, check the tower technician job board to see who's hiring. If you're new to the trade, read the realistic first year of tower climbing before you apply.
