Once you hold an active TTT-2 certification, three more NWSA credentials become available to you — none of them automatic, each requiring its own separate exam and its own $274 fee: Antenna & Line (A&L) Specialty, Advanced Rigging Concepts (ARC) Specialty, and Foreman. TTT-2 is the prerequisite for all three, but it doesn't fast-track you into any of them — you're back to studying a new exam outline for each one.
Antenna & Line (A&L) Specialty
A&L is built around the fundamental requirements for installing, repairing, troubleshooting, and maintaining antennas, transmission lines, and mounts on communication structures. It's NWSA's first specialty certification, and it's notable for one structural difference from TTT-1/TTT-2: it includes real-world practical scenarios, incorporated as scenario-based exam questions that replicate the types of work technicians actually do in the field, rather than a purely abstract multiple-choice format. Like TTT-1 and TTT-2, it's $274 and valid for five years, with recertification following the same pattern — passing the current A&L exam maintains the credential, and A&L certificants only need to pass the then-current A&L recertification exam to keep it and the certifications beneath it current.
Advanced Rigging Concepts (ARC) Specialty
ARC is the second specialty NWSA offers, and it's the deepest rigging-focused credential in the NWSA system. It covers advanced knowledge and skills for handling and lifting loads on both standard and non-standard antenna-supporting structures, built around ANSI/ASSP A10.48, and focuses specifically on complex rigging scenarios within construction plans — the kind of judgment call covered in ANSI A10.48-2023 rigging plan classes explained. NWSA describes the purpose of ARC certification as producing a subject-matter expert who can serve as an advanced technical resource within an organization — this is meant to sit above general rigging competency, not duplicate it. Same fee, same five-year validity as A&L.
Foreman
Foreman sits at the top of NWSA's core technician ladder — a 70-question, 90-minute exam covering the core knowledge, skills, and responsibilities of supervisors running crews on construction, installation, demolition, or maintenance work, evaluated against compliance with construction drawings and written scopes of work. Foreman certificants only need to pass the then-current Foreman exam to maintain all their lower-level certifications, similar to how TTT-2 covers TTT-1 on recertification.
TTT-2 is the prerequisite for all three, but it doesn't fast-track you into any of them.
Why these exist separately instead of as one "advanced" exam
NWSA built its certification system as a career ladder on purpose, and the three post-TTT-2 credentials represent genuinely different specializations rather than three difficulty tiers of the same thing. A&L is about antenna and line work specifically. ARC is about rigging judgment specifically. Foreman is about crew supervision and compliance specifically. A worker who wants to lead crews doesn't necessarily need A&L; a worker who wants to specialize in antenna and line work doesn't necessarily need ARC. You can hold one, two, or all three once TTT-2 is active — NWSA doesn't require them in a fixed order relative to each other, only that TTT-2 comes before any of them.
What TTT-2 alone gets you, versus what these add
It's worth being precise about this, since the distinction matters for career planning: TTT-2 itself already certifies supervisory-level competency across the same five domains as TTT-1 — see TTT-2 for crew leads and supervisors: what changes for what that means day to day. A&L, ARC, and Foreman aren't "TTT-3" — they're specializations layered on top, each answering a narrower question than TTT-2's broad supervisory competency.
Getting to the prerequisite first
None of these three are reachable without TTT-2, and TTT-2 itself requires an active TTT-1.
Planning the order if you want more than one
Since NWSA doesn't require these three in any particular sequence relative to each other, the practical question is which order serves your actual career goals. If your ambition is running crews, Foreman is the most directly relevant and the shortest exam of the three (70 questions versus each specialty's fuller format). If you want to become your organization's go-to rigging authority — the person who gets consulted on complex Class III/IV lifts — ARC is the more targeted investment, and it pairs naturally with deep familiarity with plan classification (see ANSI A10.48-2023 rigging plan classes explained). If antenna and line work specifically is where you want to specialize, A&L is the direct path, and its practical scenario-based questions reward hands-on field experience more than pure study time would for the others.

Worth being explicit about, since it's a natural assumption to make: none of A&L, ARC, or Foreman functions as a general "advanced tower technician" credential that subsumes the others. Each is narrow by design. A Foreman certificant isn't automatically credentialed in advanced rigging judgment just because both build on TTT-2, and an ARC specialist isn't automatically qualified to run a crew as a Foreman would be. Treat them as genuinely separate specializations to choose among, not tiers of one ladder.
Our TTT-1 Exam Prep course covers the prerequisite you need before TTT-2 is even an option. Our TTT-2 Exam Prep course follows the same model — five domains, original practice questions, a numbers drill and a 100-question practice exam, no material copied from NWSA's exam.
Frequently asked questions
Do I need all three specialty certifications, or can I pick one?
You can hold any combination — one, two, or all three — once TTT-2 is active. NWSA doesn't require them together or in a fixed sequence relative to each other.
Is ARC the same as a general rigging certification?
No. ARC is specifically an advanced specialty focused on complex rigging scenarios on standard and non-standard structures, built around ANSI/ASSP A10.48, and it requires an active TTT-2 first. It's a different credential from general rigging training like NATE's RTS-aligned employer programs.
Does A&L include a hands-on practical exam?
A&L's exam includes real-world practical scenarios delivered as scenario-based questions within the written exam format, rather than a separate in-person hands-on skills test.
What does Foreman certification actually verify?
Core knowledge of crew-supervision responsibilities: compliance with construction drawings and written scopes of work across construction, installation, demolition, and maintenance activities on communication sites.
Do these specialties expire the same way TTT-1 and TTT-2 do?
Yes — all three run five years from the date earned, with the same no-grace-period policy and 12-month recertification window as TTT-1 and TTT-2. A&L and Foreman certificants only need to pass their own then-current recertification exam to maintain themselves and the levels beneath them, the same pattern TTT-2 follows for TTT-1.
Is there a "highest" NWSA credential above these three?
Not in the sense of a single top tier — A&L, ARC, and Foreman are parallel specialties sitting at the same level above TTT-2, each answering a different question about a worker's expertise. NWSA's current handbook doesn't describe a further credential above these three.
Can I hold A&L or ARC without also pursuing Foreman?
Yes. NWSA doesn't require you to pursue all three, or any particular combination — each requires an active TTT-2 and its own separate exam, and you choose based on which specialty actually matches the work you do or want to move into.
