Prepare for the FROSIO exam — practise it the way it's examined

The FROSIO theory exam is written, not multiple-choice — you produce answers, you don't recognise them. CoatMentor is built for exactly that: 350+ original open-answer prompts with model answers, three timed 4-hour written mocks, and AI-assisted key-point marking. No braindumps, no recycled exam questions.

The FROSIO exam at a glance

One course, one exam — your certificate level (I, II or III) depends on the work experience you can document, not on which exam you sit.

SchemeNorwegian, accredited to ISO/IEC 17024; certificate valid 5 years, renewable
Theory examWritten / open-answer, around 4 hours, 150 points, 100 to pass — define, explain, list, calculate. No options to eliminate.
Practical examInstruments (DFT gauges, profile, dew-point kit, holiday detector) and defect / rust-grade recognition. 4 hours, 48 points, 32 to pass. CoatMentor trains it with simulations of the 15 stations that FROSIO courses train.
Standards spineISO 8501 / 8502 / 8503, ISO 12944, NORSOK M-501 — plus corrosion theory, coating types, application, defects, calculations, climate, H&S
LevelsI (under 2 yrs experience) · II (2+ yrs) · III ("red", 5+ yrs incl. 2 as inspector) — same exam for all

Why multiple-choice prep fails for FROSIO

Recognising the right answer is a much lower bar than producing it on paper under time pressure. Generic MC question banks train the wrong skill — that's the gap this track exists to close.

Write first, then compare

Every prompt locks the model answer until you've written yours. Then you compare against the model answer and its key points — the exact discipline the written paper demands.

Timed 4-hour written mocks

Three 80-prompt mocks drawn to the syllabus topic weights — inspection & reporting, application, corrosion, surface prep, coatings, calculations, standards, climate, H&S — at the real exam length.

AI-assisted marking, you decide

After a mock, AI pre-ticks the key-point checklist for each of your answers; you review and keep final say. If AI marking is ever unavailable, self-marking against the key points always works.

The prompt style — judge it yourself

A real prompt from the free readiness check, after you write your answer and reveal the model.

A FROSIO readiness check prompt, answered: the wet film for a 100 µm primer at 58 % volume solids with 8 % thinner, and a comb reading of 140 µm to judge. A written answer, the model answer with two key points ticked, and a drawing of 186 µm wet film leaving 100 µm dry.
  • Write your answer first, then reveal the model answer.
  • Mark yourself against its key points. In the track, AI pre-marks them and you keep the final say.
  • Calculations come with a drawing from the prompt’s own numbers and the worked method, step by step.
  • The track’s 350+ prompts follow the same format.

FROSIO questions we get asked

Is the FROSIO exam multiple-choice?
No — the theory exam is written / open-answer (around 4 hours), plus a separate practical part. That's why this track is open-answer practice with model answers, not an MC quiz. Full details in our FROSIO guide.
Are these real exam questions?
Never. Copying real exam questions is unethical and against exam rules. Every prompt is written from scratch against the public FROSIO syllabus.
How do the calculation questions work?
The classic volume-solids → WFT/DFT, spreading-rate and loss-factor calculations are a dedicated prompt cluster, each with a step-by-step model solution. We've worked a full example in the FROSIO calculation guide.
Can I see the quality before I pay?
Yes. The free readiness check has 6 FROSIO written prompts, one per topic, with no sign-up: write your answer, then reveal the model answer and key points. Signed in, you can have 2 answers marked by AI.
How much does it cost?
$69 one-time for 6 months of access to the full FROSIO track — no subscription, no auto-renewal.
