Candidates for levels 1 and 2 may complete the training as in 6.2 and the examination as in 7.2 before completion of industrial experience as in 6.3. The certification body or delegated body may issue a provisional certificate confirming successful completion of the examination but making clear that full certification of the candidate will not be issued until successful completion of the industrial experience as in 6.3.
The issue of the attestation shall be recorded by the certification body as in 4.1 (iv) and shall comply with 8.2. 6.2 Training 6.2.1 General A documented record of training is required. Documentation may be retrospective. Training may be by the employer or through a recognised course at a training centre or by self study.
Attendance at a training centre may be a mandatory requirement for certification, depending upon the requirements of the certification body. 6.2.2 Level 1 and level 2 The candidate shall provide documentary proof that he has completed a period of training, in the application sector and level for which the certification is sought. The training period, method and syllabus, shall be established by the certification body in accordance with Annex B. The minimum duration of training undertaken by the candidate for certification shall be 40 h of formal or documented on-the-job training in each particular application sector and for both level 1 and level 2. Candidates without level 1 certification shall undertake a minimum of 80 h training for level 2. Training hours shall include both practical and theory components. 6.2.3 Level 3 Taking into account the required scientific and technical competence of candidates for level 3 certification as described in 5.4, preparation for certification at level 3 may be by, for example:
a)
completing a relevant engineering or scientific degree or period of post graduate education at a reputable school of higher education,
b)
attending training courses, conferences or seminars (such as those organised by established industrial or independent associations),
c) studying scientific or engineering text books, periodicals, and other specialised materials. The certification body shall establish, publish and from time to time update the certification requirements for level 3 personnel. The candidate shall submit documentary evidence of training, experience, theoretical knowledge and practical skills in cathodic protection to enable the certification body to assess the competence of the candidate in accordance with 5.4.

7 Competence assessment for certification
7.1 General Assessment of the competence level of candidates shall be undertaken in accordance with detailed regulations established by the certification body in compliance with the general framework defined by this standard. It shall be achieved through examinations for levels 1 and 2. For level 3 assessment is based on a detailed dossier of documentary evidence and optionally an examination.
7.2 Examination for level 1 and level 2 7.2.1 General The examination system for level 1 and level 2 shall be established and maintained by the certification body in order to assess the competence of level 1 and level 2 candidates in accordance with 5.2 and 5.3 respectively. Publication of multiple choice examination questions is permitted when the certification body utilises these as a basis of a training programme. In this case, answers to questions shall not be published and there shall be at least 10 times the number of questions that are used in any one examination.
For each level, the examination shall comprise three examination sessions. Two examination sessions shall be theoretical: the so-called "common-core examination session” and the so-called “sectoral theoretical

The time allowed to the candidates for completion of each examination shall be based upon the number and difficulty of the questions.
7.2.3 Sectoral theoretical examination session The sectoral theoretical examination session shall enable the candidate to demonstrate his knowledge and competence to undertake tasks used within the application sector in question in accordance with 5.2 or 5.3. The sectoral theoretical examination session shall include only questions selected from the certification bodies or delegated body’s current collection of specific questions related to the application sector concerned. The time allowed for the candidates to complete each examination shall be based upon the number and difficulty of the questions.
The sectoral theoretical examination session shall include a series of written questions on the processes and testing procedures used within the relevant application sector. 7.2.4 Sectoral practical examination session A sectoral practical examination session organised on structures or simulated structures and systems shall be provided by the examination centre.
For Level 1, the candidate shall demonstrate his competence to fulfil the requirements of 5.2 in particular to:  operate the instruments in order to collect accurate data;  carry out the adjustments to cathodic protection equipment as necessary to obtain defined results;  record and report the results. For level 2, the candidate shall demonstrate his competence to fulfil the requirements of 5.3, in particular to:  draw up a written report with an interpretation of the results;  prepare written instructions to carry out a level 1 task;  interpret particular cathodic protection problems. The time allowed for the sectoral practical examination session shall depend on the number of tasks specific to that sector and their complexity. 7.2.5 Conduct of examinations All examinations shall be conducted in examination centres, established, approved and monitored by the certification body, either directly or through a delegated body. At the examination, the candidate shall have in his possession valid and unambiguous proof of identification (e.g. identity card, passport, or driving licence incorporating photograph) and an official notification of the examination, which shall be shown to the examiner or invigilator upon demand. Any candidate who, during the course of the examination, does not abide by the examination rules or who perpetrates, or is an accessory to, fraudulent conduct shall be excluded from a period to be determined by the certification body.

7.2.7 Final assessment The certification body or the delegated body shall establish an assessment committee that shall review the results of the examination sessions and the recommendations from the examiners in order to determine the acceptance of the candidates for certification. 7.3 Assessment for level 3 The competence of level 3 candidates in accordance with all aspects detailed in 5.4, shall be assessed by an assessment committee appointed by the certification body or delegated body on the basis of a dossier detailing and documenting: − The educational, scientific or engineering qualifications of the candidate − The extent of responsible experience in the particular application sector for which he is a candidate − Examples of design documents, reports or technical papers prepared by the candidate
The dossier shall demonstrate knowledge of general and specific theory of cathodic protection and the ability to prepare technical reports.
The dossier shall be supported by a minimum of two independent referees familiar with the work of the candidate who shall attest to the veracity and accuracy of the dossier and the suitability of the candidate to be certificated to level 3 in the application sector (s). The assessment committee shall comprise a minimum of five members experienced in cathodic protection of which at least two shall be certificated to level 3 and may in addition include representatives of the certification body and/or delegated body.
