FOREWORD

DET NORSKE VERITAS (DNV) is an autonomous and independent foundation with the objectives of safeguarding life, prop-erty and the environment, at sea and onshore. DNV undertakes classification, certification, and other verification and consultancyservices relating to quality of ships, offshore units and installations, and onshore industries worldwide, and carries out researchin relation to these functions.

Standards for CertificationStandards for Certification (previously Certification Notes) are publications that contain principles, acceptance criteria and prac-tical information related to the Society's consideration of objects, personnel, organisations, services and operations. Standardsfor Certification also apply as the basis for the issue of certificates and/or declarations that may not necessarily be related to clas-sification.

A list of Standards for Certification is found in the latest edition of Pt.0 Ch.1 of the ”Rules for Classification of Ships” and the”Rules for Classification of High Speed, Light Craft and Naval Surface Craft”.

The list of Standards for Certification is also included in the current “Classification Services – Publications” issued by the Soci-ety, which is available on request. All publications may be ordered from the Society’s Web site http://exchange.dnv.com.

Standard for Certification - No. 3.304 3

February 2007

BackgroundDNV SeaSkill has been set up to use the principles of classifi-cation to help improve and codify competence at all levelswithin the maritime industry.

It is necessary to independently test and verify the competenceof individuals in relation to specific jobs or positions on-boardas well as on-shore. DNV SeaSkill offers the industry the nec-essary tools and expertise to evaluate the competence of indi-viduals based on Standards for Certification of Competence.These standards can be used to provide appropriate training,and to assess and certify individuals as being fit to carry out thefunctions as described in each standard.

Currently, there is no globally accepted competence standardfor "Ship's Electrical Officers and Engineers".

The STCW Code 95 specifies competence requirements on op-erational and management level on subjects related to electri-cal, electronic and control engineering for the officers in theengine department. However, the requirements are not verydetailed and there is no standard for independently verifyingand certifying the competence of ship's electrical officers andengineers.

DNV SeaSkill works in close cooperation with the shipping in-dustry. Our standards are in fact developed by Committees of

Experts (CoE) consisting of leading members from the indus-try. All DNV SeaSkill standards are developed with the activeparticipation of the shipping industry.

The DNV Committee of Experts (CoE) in Singapore has rep-resentation from owners, operators and industry bodies. Thiscommittee has been instrumental in choosing to work on thestandard, and the contents of the standard itself. A group of ex-perts in Helsinki consisting of persons from manufactures ofelectrical equipment, owners and educational institutions hasalso made crucial contributions to the standard.

The standard can be applied in the following ways:

— As a guide to the competence requirements that employersshould place on the ship's electrical officers and engineersthey employ.

— As a guide to those who are already working or wish towork in the position of ship's electrical officers.

— As a guide to training providers, who can develop coursesaccording to the requirements of the standard.

— For the assessment and certification of ship's electrical of-ficers and engineers. This would be done by DNV Sea-Skill, and would provide an independent and transparentmechanism for certification.

2. Test Requirements – Introduction

2.1 GeneralTaxonomy of the required professional behaviour specifies thelevel on which the person should be able to operate. Taxonomyof the required professional behaviour is a hierarchical ar-rangement, in four (4) levels, of what a person has to masterfrom simple to complex requirements based on Bloom’s tax-onomy i.e. Bloom, B. S. et al., (1956) Taxonomy of Education-al Objectives – The Cognitive Domain.

For every next level, it is a prerequisite that the preceding levelis mastered.

The required professional behaviour is expressed by means ofa verb.

2.2 Taxonomy

2.2.1 Level 1: Knowledge (K)To remember or to reproduce on basis of appropriate, previ-ously learned information.

Suggested professional behaviour verbs on this level 1 are forexample: Define, describe, find, identify, label, list, match,mention, name, outline, recognise, record, repeat, reproduceand state.

2.2.2 Level 2: Understanding (U)To give meaning to new situations and or new material by rec-ollection and using necessary present information. To give ev-idence of insight in certain activities. Called comprehension byBloom.

Suggested professional behaviour verbs on this level 2 are forexample: Classify, cite, comprehend, convert, discuss, distin-guish, estimate, explain, extend, generalise, give examples, in-terpret, make sense out of, paraphrase, predict, restate (in ownwords), summarise, trace and translate.

2.2.3 Level 3: Application (A)To use previously acquired information in new and concretesituations to solve problems that have single or best answers.

Suggested professional behaviour verbs on this level 3 are for

example: Act, administer, apply, articulate, arrange, assess,calculate, chart, collect, compute, construct, contribute, con-trol, demonstrate, determine, develop, discover, establish, ex-tend, implement, include, inform, instruct, manipulate,operate, participate, predict, prepare, preserve, produce,project, provide, report, review, show, solve, teach, transfer,use and utilise.

2.2.4 Level 4: Integration (I)To separate information into their component parts, to examinesuch information to develop divergent conclusions by identify-ing motives or causes, making inferences, and/or finding evi-dence to support generalizations. To creatively apply priorknowledge and skills to produce a new or original whole. Tojudge the value of material based on personal values or opin-ions, resulting in an end product, with a given purpose, withoutreal right or wrong answers. Called analysis, synthesis andevaluation by Bloom.

Suggested professional behaviour verbs on this level 4 are forexample: Analyse, appraise, categorise, combine, communi-cate, compare, compile, compose, conclude, contrast, corre-late, create, criticise, decide, defend, design, develop, devise,differentiate, discriminate, express, facilitate, formulate, gen-erate, hypothesise, illustrate, incorporate, integrate, interpret,invent, judge, justify, model, modify, negotiate, organise, out-line, plan, point out, prioritise, rearrange, recommend, recon-struct, reinforce, relate, reorganise, revise, select, separate,solve, structure, subdivide, substitute, support and validate.

2.2.5 Professional behaviour verbsThe lists of verbs in 2.2.1 to 2.2.4 are not exhaustive andshould be used as guidance only.

2.2.6 Measurement of Level 3 and 4 competenceApplication (A) and Integration (I) are normally measured bypractical assignments. Practical assignments may be of a “the-oretical nature”, depending on the competences to be meas-ured. They may include the use of multiple choice questions,open ended questions, case studies, etc. when measuring com-petences such as calculations, planning, reporting etc.
