AMPP CT/CTech Corrosion Technician / TechnologistExam Guide & Preparation
AMPP CT/CTech covers two related but distinct credentials in AMPP's corrosion certification catalog: the entry-level Corrosion Technician and the advanced Corrosion Technologist. AMPP was formed by the 2021 merger of NACE International and SSPC, so these credentials are still frequently referenced under "NACE" naming in job postings.
AMPP CT/CTech covers two related but distinct credentials in AMPP's corrosion certification catalog: the entry-level Corrosion Technician and the advanced Corrosion Technologist. AMPP was formed by the 2021 merger of NACE International and SSPC, so these credentials are still frequently referenced under "NACE" naming in job postings.
Corrosion Technician is geared toward personnel with at least 2 years of experience who possess basic knowledge of corrosion and corrosion control, and who are capable of performing routine, well-defined work under the close direction of a Specialist or Senior Technologist. It's the entry point into AMPP's broader corrosion technician career path.
Corrosion Technologist is a substantially more advanced credential, requiring 4 years of verifiable corrosion-related experience and assessed by a dedicated proctored exam (test code NACE-CTt-001), 100 multiple-choice questions over 180 minutes, closed-book, computer-based at Pearson VUE. It encompasses advanced comprehension of corrosion theory and prevention across cathodic protection, coatings, material selection and design, internal corrosion, and chemical treatment.
Whether you're building toward the Corrosion Technician role or preparing for the full Corrosion Technologist exam, EIM's AMPP CT/CTech training platform is built with a structured AMPP CT/CTech course, self-paced online training, and study material for both stages.
Corrosion Technician vs Corrosion Technologist
Corrosion Technician and Corrosion Technologist are sequential in practice, though AMPP doesn't require the Technician credential as a strict prerequisite for Technologist. A Technician performs routine, well-defined corrosion control work under supervision, while a Technologist independently applies advanced corrosion theory across cathodic protection, coatings, material selection, internal corrosion, and chemical treatment, and is assessed on that breadth through a dedicated 100-question proctored exam.
The Technologist credential also sits above AMPP's individual specialist tracks (CP1-4, PCS levels, CIP levels) in scope, rather than replacing them, a Corrosion Technologist is expected to understand all of these specialty areas at a working level, even without holding every individual specialist certification.
Qualification & Prerequisites
What the Technologist Exam Actually Tests
Five domains, weighted by question share. This is the map the question bank is built directly against.
CP fundamentals, criteria, and application as referenced in NACE/AMPP SP0169
Surface preparation standards (NACE No. 3/SSPC-SP 6), coating selection per MR0175
Material properties relevant to corrosion resistance, material selection for corrosive service
Internal corrosion monitoring, chemical treatment programs (inhibitors, biocides)
General electrochemistry, corrosion theory application across the remaining tested domains
| Domain | Covers | |
|---|---|---|
| 01 | Cathodic Protection (per SP0169) | CP fundamentals, criteria, and application as referenced in NACE/AMPP SP0169 |
| 02 | Protective Coatings & Surface Preparation | Surface preparation standards (NACE No. 3/SSPC-SP 6), coating selection per MR0175 |
| 03 | Metallurgy & Material Selection | Material properties relevant to corrosion resistance, material selection for corrosive service |
| 04 | Internal Corrosion Control & Chemical Treatment | Internal corrosion monitoring, chemical treatment programs (inhibitors, biocides) |
| 05 | Corrosion Fundamentals & Broader Applications | General electrochemistry, corrosion theory application across the remaining tested domains |
01. Cathodic Protection (per SP0169)
02. Protective Coatings & Surface Preparation

How to Register and What to Expect on Exam Day
Candidates register directly through AMPP, not through EIM or any third-party training provider. Corrosion Technologist candidates apply via an approved Corrosion Technologist Application, and the exam is delivered by computer-based testing at Pearson VUE.
AMPP's official CBT exam fee for Corrosion Technologist is $385. This is separate from EIM's AMPP CT/CTech self-prep pricing. Corrosion Technologist certification is valid for 3 years, and recertification requires reapplication and approval, it isn't automatic.

Why AMPP CT/CTech Corrosion Technician / Technologist Matters for Asset Integrity Careers
The Corrosion Technologist exam covers 9 domains with particular emphasis on cathodic protection (per SP0169), protective coatings and surface preparation (per NACE No. 3/SSPC-SP 6 and MR0175), metallurgy, and internal corrosion control, a genuinely broad spread that rewards candidates with exposure across multiple corrosion control disciplines rather than deep specialization in just one. Candidates coming from a purely cathodic-protection or purely coatings background often need deliberate additional study to cover the domains outside their usual specialty.
EIM's AMPP CT/CTech question bank is built around this cross-disciplinary reality, covering cathodic protection, coatings, metallurgy, material selection, and internal corrosion together, since underpreparing for domains outside a candidate's usual specialty is one of the most common reasons experienced corrosion professionals still find this exam challenging.
