Introduction
In the US, NDT Level 1 technicians typically earn about $38,000 to $56,000 a year, Level 2 technicians about $48,000 to $72,000 (up to about $110,000 in advanced ultrasonic methods), and Level 3 specialists about $85,000 to $140,000, with independent Level III consultants earning well above that. Pay rises with each level because authority rises: a Level II can interpret and report results, and a Level III writes procedures and certifies others.
This guide covers what each certification level pays, what moves your pay within a level, how salaries differ by region, and whether an NDT Level 4 exists. All figures are indicative ranges of typical annual base pay in US dollars unless stated, and real offers vary by method, industry and location.
NDT Salary by Certification Level: Quick Comparison
Each level adds a new layer of authority, and pay follows that authority. The table below summarizes what each level is authorized to do, the typical US base pay, and how long it usually takes to get there. Under ASNT SNT-TC-1A, ASNT CP-189 and ISO 9712, certification is method-specific, so a technician can be Level II in UT and Level I in RT at the same time.
Typical US base pay by NDT certification level (2026)
Level | What each level is authorized to do | Typical US base pay | Typical time to reach |
|---|---|---|---|
Level I | Perform specific calibrations, tests and accept/reject evaluations by following written instructions, under supervision; cannot interpret results against codes or report them independently | $38,000 to $56,000 | A few months (training plus supervised hours) |
Level II | Set up, calibrate, perform, interpret and evaluate tests against codes; organize and report results; guide Level I technicians | $48,000 to $72,000 for most; PAUT/TOFD specialists up to about $110,000 | ~1 to 2 years |
Level III | Write and approve procedures and techniques, interpret codes, train and certify Level I and II staff, own the written practice | $85,000 to $140,000 employed; consultants higher | 1 to 4+ years as a Level II, depending on education |
Ranges combine national salary surveys, employer pay-grade data, self-reported salaries and live job postings, all checked in September 2026. Base pay excludes overtime, per diem and rotation pay, which can add a lot in field roles.
NDT Level 1, 2 & 3 Pay Per Hour, Per Day and Per Week
On the job, few NDT technicians talk about a yearly salary. Most field work is paid by the hour, and contract or travel work is often quoted as a day rate. The table below converts the typical US pay for each certification level into hourly, daily and weekly figures, so you can compare them directly with a job offer.
Certification level | Per hour | Per day (10-hr shift) | Per week (40 hrs) |
|---|---|---|---|
NDT Level 1 | $18 – $27 | $180 – $270 | $730 – $1,100 |
NDT Level 2 | $23 – $38 | $230 – $385 | $920 – $1,540 |
NDT Level 3 (employed) | $46 – $70 | $460 – $700 | $1,830 – $2,790 |
NDT Level 3 (independent consultant) | $150 – $400 | Usually quoted per day or per job | Varies by contract |
These are straight-time base rates. Actual weekly earnings in the field are usually higher, for three reasons:
- Overtime: field and shutdown work often runs 50–60 hours a week, and hours over 40 are typically paid at 1.5× the base rate. A Level 2 technician on $30/hr working 55 hours earns about $1,875 for the week, not $1,200.
- Per diem: travelling technicians commonly receive around 75–150 a day for meals and lodging on top of their hourly pay.
- Shift and rotation premiums: night shifts, hazardous sites and offshore rotations add further premiums, so offshore packages can run well above onshore pay.
Level 1 NDT Salary: What Entry-Level Technicians Earn
A typical Level 1 NDT salary in the US is about $38,000 to $56,000 a year, or roughly $18 to $27 an hour.
What a Level 1 technician actually does
A Level I technician performs specific calibrations and tests by following written instructions, under the supervision of a Level II or Level III. They can make specific accept/reject evaluations where the written instructions spell out the criteria, and they record results, but they cannot interpret results against codes and specifications or report them independently. For the full breakdown of duties and hour requirements, see our NDT certification levels guide.
Typical Level 1 pay
Salary guides put entry-level Level I pay, for technicians with up to two years of experience, anywhere from about $35,000 to $58,000 depending on employer and region, and most Level I technicians land in the $38,000 to $56,000 band. Employer pay grades for "NDT Technician I" average about $56,800 a year, or $27 an hour. Field positions can add 10 to 20% or more through overtime.
That pay-grade average sits just above the top of the band because "Technician I" grades often include staff doing some Level II-type work. Be wary of salary pages that show one identical figure for Level I, Level II and general NDT technician jobs: they pool job titles and overstate Level I pay.
Why most people don't stay at Level 1 for long
Level I is a qualifying stage, not a career destination. Employers can bill a Level II out independently, so they push technicians to log hours and move up. Once you reach Level II in your main method, base pay typically rises by around $10,000 a year or more.
Level 2 NDT Salary: The Working-Level Pay Band
A typical Level 2 NDT salary in the US is about $48,000 to $72,000 a year, or roughly $23 to $35 an hour, with about $30 an hour as the national average. Level II is where most of the NDT workforce sits, and it is also where the gap between methods and job types is widest: the $48,000 to $72,000 band covers most Level II technicians, while advanced ultrasonic (PAUT/TOFD) specialists earn more, at about $80,000 to $110,000.
Typical Level 2 pay
The national average for Level II jobs is about $61,700 a year (about $30 an hour), with most Level II salaries falling between $48,000 and $71,500. Employer pay grades for "NDT Technician II" average around $64,000. Industry salary guides put typical Level II pay at $55,000 to $80,000, with the top of that band usually reached through advanced methods, multiple methods or senior field roles. Aerospace, defense, energy and utilities are among the best-paying industries.
Job-title wording moves these numbers a lot. Jobs advertised as "Level 2 NDT Technician" averaged just $48,390 in late 2025, with most between $38,500 and $54,500. Treat any single figure with caution and look at the spread.
Level 2 salary by method: MT/PT vs UT/RT vs PAUT/TOFD
Method group | Typical Level II base pay |
|---|---|
MT / PT (surface methods) | $50,000 to $65,000 |
Conventional UT / RT | $55,000 to $72,000 (estimate) |
PAUT / TOFD (advanced ultrasonics) | $80,000 to $110,000 (above the typical Level II band) |
MT/PT and conventional UT/RT make up most Level II jobs, so they sit inside the $48,000 to $72,000 band. Salary guides place UT and RT above the surface methods, and the UT/RT figure is an estimate based on that position. PAUT and TOFD specialists are a smaller, higher-paid group that sits above the band, because fewer technicians hold these methods and they are specified for critical weld and pipeline work.
Base pay vs total pay: overtime, per diem and rotation
Field Level II technicians often earn far more than their base salary. In onshore oil and gas, overtime typically adds 10 to 20% a year, per diem runs $75 to $150 a day when traveling, and shift premiums add 15 to 20%. Offshore work adds a further 30 to 50%.
Offshore day rates show the jump clearly: moving from Level I to Level II typically lifts a technician from about $330 to $450 a day to about $480 to $690 a day (US dollars). When comparing offers, always compare total annual earnings, not just base pay.
Level 3 NDT Salary: The Top of the Certification Ladder
A typical employed Level 3 NDT salary in the US is about $85,000 to $140,000 a year, or roughly $41 to $67 an hour, and independent Level III consultants can clear $200,000. At this level, pay depends more on the kind of Level III job you hold than on the certificate itself.
Typical Level 3 pay (employed)
Salary-survey averages for Level III sit at around $84,000 to $100,000, and a recent NDT Responsible Level III posting in Connecticut advertised $80,000 to $110,000, depending on experience. Level III technical specialists typically earn $90,000 to $120,000, and Level III program managers $100,000 to $140,000. Industry salary guides put experienced Level IIIs as high as about $145,000.
Self-reported salaries run higher, averaging about $137,700, with the middle 50% between roughly $103,000 and $193,000. That figure rests on only a few dozen submissions, so treat it as an upper reference rather than a typical salary.
Why Level III figures conflict: samples are small, and job titles get mixed. Some salary pages show exactly the same average for Level III as for Level II, which signals pooled or mis-tagged data. That is why this guide gives Level III as a range and separates out the consultant tier.
Working Level III vs Responsible or Corporate Level III
A working Level III still inspects, but also handles difficult interpretations and writes techniques. Pay tends to sit in the lower-to-middle part of the range, close to the $90,000 to $120,000 specialist band. A Responsible or Corporate Level III owns the employer's written practice, approves all procedures, and trains and examines Level I and II staff. Every employer running an SNT-TC-1A or CP-189 program needs a Level III in this role, in-house or outsourced, so it pays more, with program-manager roles reaching about $140,000.
Independent or consultant Level III
Many smaller shops outsource their Level III duties. Experienced independent Level III consultants typically bill $150 to $400 an hour. Annual income depends as much on how many billable days they fill as on the rate, and busy full-time consultants often earn more than $200,000 a year. In the UK, Level III contract day rates start from about £500. Consultant income is not salary: it has to cover gaps between contracts, insurance and travel.
Which industries pay Level 3s the most
Oil and gas, aerospace and nuclear lead, and specialists in these sectors can earn above the typical band. Refinery Level III specialists typically earn $110,000 to $150,000, nuclear roles can add a 10 to 20% security-clearance bonus, and Level IIIs specializing in PAUT, TOFD or AUT can reach $130,000 to $180,000.
Is There an NDT Level 4?
No. ASNT SNT-TC-1A, ASNT CP-189 and ISO 9712 all stop at Level III, so there is no "NDT Level 4" certificate and no Level 4 salary band.
The confusion comes from an extra rung below Level I. Some employers and training schools add a "Level I Limited" or trainee stage, so they describe four tiers: Level I Limited, Level I, Level II and Level III. Some employers also use internal job grades like "NDT Technician IV", which are pay grades, not certification levels.
If you want to earn more than a single-method Level III, these are the real next steps:
- Level III in multiple methods
- A Responsible or Corporate Level III role
- NDT manager or program manager
- Independent Level III consulting
- Stacking API 510, 570 or 653 inspector certification, or AWS CWI, on top of your NDT levels
Why Pay Jumps So Much Between Levels
NDT pay tracks authority, not years served. Each level unlocks work that an employer can bill for or that a code says only that level may do.
Level I to Level II: you gain the right to interpret results against codes and specifications, and to organize and report them. That makes you billable on your own, without a supervisor standing next to you, and it is why Level II earns most of the field-pay premium.
Level II to Level III: you gain the right to write and approve procedures, own the written practice, and train and examine other technicians. Without this role, an employer cannot run a certification program. That is why Level III typically earns about $85,000 to $140,000, against $48,000 to $72,000 for Level II.

NDT Level Salaries by Region
The same certificate pays very differently depending on where you work. Among the markets covered here, the US pays the highest base salaries, the UK pays less in cash terms, and the Middle East and offshore work add tax-free packages or rotation premiums.
Region | Level I | Level II | Level III | Note |
|---|---|---|---|---|
USA | $38k to $56k | $48k to $72k | $85k to $140k | Base pay; overtime and per diem extra |
UK | ~£22k to £28k | ~£30k to £50k | ~£55k to £80k | Multi-method Level II at the top of the band |
UAE | Not reliably reported | ~AED 8,000 to 15,000/month, about $26k to $49k/yr, tax-free | Not reliably reported | PAUT lifts Level II to ~AED 15,000 to 22,000/month |
Offshore (any region) | $330 to $450/day | $480 to $690/day | Premium over onshore | Offshore pay runs ~30 to 50% above onshore (rotation, hazard pay) |
UK: Level I trainees earn £22,000 to £28,000, single-method Level II technicians £30,000 to £38,000, multi-method Level II technicians £38,000 to £50,000, and Level III engineers and consultants £55,000 to £80,000.
Middle East and offshore: Level II technicians in the UAE earn about AED 8,000 to 15,000 a month tax-free (roughly $26,000 to $49,000 a year), rising to about AED 15,000 to 22,000 a month with PAUT. Saudi packages run about $35,000 to $55,000 a year, tax-free, and offshore work carries a 30 to 50% premium over onshore pay. Reliable level-by-level figures for Level I and Level III in the region are scarce, so we don't quote them.
India: pay structures, rupee ranges and employer types are different enough to need their own page. See our full NDT salary in India guide.
What Changes Your Pay Within the Same Level
Two technicians at the same level can earn very different amounts. Six factors explain most of the gap.
- Method. PAUT, TOFD and AUT command the biggest premium, and MT/PT pay least. Advanced-ultrasonic technicians typically earn 40 to 80% more than the MT/PT baseline, depending on employer and sector.
- Number of methods. Multi-method technicians typically earn 15 to 30% more than single-method specialists, with UT/RT and MT/PT common combinations.
- Industry. Aerospace and defense, oil and gas, energy and nuclear sit at the top. Engine makers, space companies and aerostructure suppliers are among the best payers in aerospace.
- Travel and rotation. Field and offshore work adds overtime, per diem and rotation allowances on top of base pay.
- Add-on certifications. API 510, 570 or 653 inspector credentials and AWS CWI make you useful beyond pure testing, which lifts pay at every level.
- Employer type and location. Service companies often pay a lower base with more overtime, while in-house roles pay a steadier salary. High-demand hubs such as the Texas and Louisiana Gulf Coast pay above the national average.
How Long It Takes to Move From Level 1 to Level 3
Most technicians take roughly 3 to 7 years or more to go from trainee to Level III, depending on education and how fast they log method hours.
Step | Typical time at this step | What it unlocks |
|---|---|---|
Trainee → Level I | A few months of classroom training and supervised hours (a first PCN Level 1 takes about 3 to 6 months in the UK) | Paid entry-level work under supervision |
Level I → Level II | About 1 to 2 years of logged method hours | Interpreting and reporting results; the biggest field-pay step |
Level II → Level III | 1 to 4 years as a Level II, depending on education | Procedure writing, program ownership and certifying others |
Under SNT-TC-1A, the employer certifies its own Level III staff based on education, experience and the examinations set out in its written practice. Education sets the minimum Level II experience: at least 1 year with an engineering or science degree, 2 years with two years of college-level science or engineering study, and 4 years without either. Many employers also require the ASNT NDT Level III certificate (the Basic exam plus a method exam), or accept it in place of their own exams. That is a separate, portable credential, so a technician can be an employer-certified Level III without holding ASNT Level III.
In pay terms, each step moves you into the next band in this guide: from about $38,000 to $56,000 at Level I, to $48,000 to $72,000 at Level II, and $85,000 to $140,000 at Level III, before overtime. Hours tables for each method are in our NDT certification levels guide. For the cost side, see our Level I course fees guide and NDT courses.
FAQs
How much does an NDT Level 3 make per year?
An employed NDT Level III in the US typically earns about $85,000 to $140,000 a year in base pay. Responsible or Corporate Level IIIs and specialists in oil and gas, aerospace or nuclear sit at the top. Independent Level III consultants typically bill $150 to $400 an hour, and busy full-time consultants can earn over $200,000 a year.
How much does a Level 2 NDT technician make per hour?
A Level II NDT technician in the US earns about $30 an hour on average, with most Level II pay between roughly $23 and $35 an hour. Field roles with overtime, per diem and shift premiums can earn much more in total, and advanced methods such as PAUT and TOFD pay above this band.
Is there an NDT Level 4 certification?
No. ASNT SNT-TC-1A, CP-189 and ISO 9712 all stop at Level III. Some employers add a "Level I Limited" or trainee stage below Level I, which is why people sometimes count four levels. Higher pay beyond Level III comes from multi-method certification, management roles or consulting.
How long does it take to become NDT Level 3?
Usually 3 to 7 years or more from starting as a trainee. Under SNT-TC-1A, you need at least 1 year as a Level II with an engineering or science degree, 2 years with two years of college science or engineering, or 4 years without either, plus the exams in your employer's written practice. Many employers also ask for the ASNT NDT Level III certificate.
Which NDT method pays the most?
Advanced ultrasonic methods such as PAUT, TOFD and AUT pay the most. Level II PAUT/TOFD specialists typically earn about $80,000 to $110,000, above the $48,000 to $72,000 band that covers most Level II technicians and well ahead of the $50,000 to $65,000 typical for MT/PT. Surface methods such as MT, PT and VT generally pay the least.
Is NDT Level 2 enough to earn a good salary?
Yes. A US Level II typically earns $48,000 to $72,000 in base pay, and with PAUT/TOFD, multiple methods or field overtime many earn well above that. Level III raises the ceiling, but a multi-method Level II in oil and gas or aerospace can out-earn some salaried Level IIIs once overtime is counted.
How We Compiled These Figures
All ranges are annual base pay in US dollars unless stated, checked in September 2026. We combined national salary surveys, employer pay-grade data, self-reported salaries and live job postings, and we label the results typical ranges, not averages, because no single dataset measures NDT pay by certification level cleanly. Salary aggregators pool job titles, self-reported samples for Level III are small, and employer job grades ("Technician I to IV") don't map exactly to certification levels. Where sources conflict, we show the full spread and explain the difference rather than picking one number.
