Course description | Certification information
CP2 Cathodic Protection
Technician course
The Cathodic Protection Technician course provides intermediate-level training in both
theoretical knowledge and practical techniques for testing and evaluating data to determine
the effectiveness of both galvanic and impressed current CP systems and to gather design
data. Classroom instruction is comprised of lectures and hands-on training, including using
equipment and instruments for CP testing.
Course learning objectives
• Test and troubleshoot rectifier component parts
• Perform simulated CP related field tests (including interrupted structure-to-electrolyte
potentials, current requirement, continuity, shorted road/railroad casing and, layer soil
resistivity tests) and evaluate the results
• Perform tests to verify the presence of stray current interference (primarily related to
underground pipelines) and recommend method(s) to mitigate the interference
• Conduct and interpret different current measurements
• Interpret voltage (IR) free readings, polarization formation and decay tests
• Maintain records, including data plotting and analysis
• Summarize induced AC voltage on pipelines and the methods of mitigation
• Purpose and uses of corrosion coupon test stations
• Depending on the jurisdiction review code CP criteria requirements related to CP
Course completion
A practical exam is administered at the end of the course. Successful completion of the exam
is required to earn a certificate of completion. A practical exam is administered at the end of

Certification exams
Certification requirements include the practical exam administered at the end of course.
The multiple-choice CBT exam is scheduled separately from the course and delivered via
Pearson VUE. The initial CBT exam is included with the course registration. Any Exam
retake will incur additional cost to the applicant.
Renewal requirements
An approved recertification application is required every 3 years. The work experience
requirement for renewals for all certifications is one and half (1.5) years for the most recent
three (3) year period. Additionally, some certifications have other requirements related to
responsibility in charge.
As you prepare for renewal, please visit My Certification Portal to log and manage your work
experience and Professional Development Hours (PDH's) needed. Your work experience and
PDH's will be submitted as part of your renewal application but you can input PDH's at any
time. See the certification renewal guide for PDH's requirements, our sample training PDH
guide, and our PDH how-to videos.
Certification holders are required to pay a non-refundable processing fee for renewal.
NOTE: AMPP reserves the right to return any incomplete applications or those that do not meet the
