Be thoroughly familiar with the safety requirements for electrical installations.

Be capable of troubleshooting and maintaining electrical installations.

Use competently the test instruments and various tools necessary to perform tasks.

Be familiar with the work of other tradesmen in the construction industry and with thedifferent types of building construction.

ENTRY REQUIREMENTS AGE: The minimum age for an apprentice is 16; there is no upper age

limit.

EDUCATION: Apprentices in the trade require English, Math 20 or 23, Pure Math20, or Applied Math 20 and at least 10 credits in a Science; or theequivalent, however employers prefer to hire high schoolgraduates.

ENTRANCE EXAMS: Prior to the signing of an Apprenticeship Contract, individuals mustreceive a 70% or better on the relevant trades entrance exam.

NOTE: Special exemption by regulation is given to students enrolled in the Schools North Apprenticeship program. SNAP students are required to write the trades entrance examinationprior to signing the Apprenticeship Contract. The policy dictated by the Apprenticeship, Tradeand Occupations Certification Board (ATOCB) allows the student to obtain 50% on theexamination to be deemed eligible for the program. The SNAP student MUST obtain a 70%pass mark within one (1) calendar year of signing the Apprenticeship Contract. Failure to doso results in the SNAP student cancellation of contract being ruled ineligible.

BENEFITS

Employment and Training - Apprenticeship is a learning-while-earning program. Whileworking at the Trade, apprentices are assured by regulation, a minimum percentage of theprevailing journeyperson rate: 55% first period; 60% second period; 70% third period; and 80%in the fourth period. Progress from one rate to another takes place only upon successfulcompletion of all the requirements of the period.

Courses The school courses are funded through the Apprenticeship Program. Students willbe required to pay a tuition fee.

Al lowance If the Apprentice is eligible for E.I. benefits, he/she may receive the followingallowances:

- Travel Assistance

- Living away expenses

- Childcare Subsidies

- Book Allowance

- Special Equipment Allowance

Certification An apprentice who successfully completes the training program will graduatewith a Completion of Apprenticeship Certificate and a Certificate of Qualification at theJourneyperson level valid in the N.W.T.

Interprovincial Certification If applicable, the apprentice will also have the opportunity toattempt the Interprovincial Examination. If successful in this exam, the Certificates areendorsed with the Interprovincial Red Seal which makes the Certificates valid anywhere inCanada.

Career Opportunit ies The most significant benefit to the graduate/apprentice is that he/she

is well trained in technical and practical aspects of the trade and is able to make a worthwhileand productive contribution to Society. Society in return, will provide an opportunity for anabove-average income and successful livelihood .

ADVICE TO PROSPECTIVE APPRENTICES

The prospective apprentice should contact firms that offer employment in the Electriciantrade, and state your desire to become an apprentice.

The Apprenticeship Training Officer (ATO) or Career Development Officer (CDO) willarrange for a Trade Entrance examination.

When you and your employer are ready to sign an Apprenticeship Contract, contact thenearest Career Centre for detailed information.

The ATO or CDO will draft the Apprenticeship Contract.

Not all employers are willing to sign an Apprenticeship Contract immediately, so beprepared to start work as a trades helper. Your Apprenticeship Contract can normally bebackdated, so you need not lose any time credit.

Any time credit for previous experience in the Electrician trade should be discussed withthe employer and the ATO or CDO and credited towards the Apprenticeship Contract.

Before signing the Apprenticeship Contract, know your obligations and responsibilities toyour employer, know the employers responsibilities to you and feel confident you haveselected the right occupation.

PREAMBLE

The lectures, demonstrations and assignments detailed in the course outline are intended tofamiliarize the apprentice with the full scope of the trade. The classroom subjects and shopprojects have been selected to provide the apprentice with the theoretical background andmanual skills to be able to meet the standards of competence demanded by the industry.

The areas outlined will be taught within their relationship to current trade practice; thedepth of instruction will be governed accordingly

The hours allotted for various subjects are intended as guidelines. Some flexibility isallowed to accommodate the special needs of particular classes and other factors, suchas statutory holidays

Shop and theory time allotments are approximate and may be varied to suit individualclass needs

Mathematics and science are integral components of the technical training. Althoughthey may be delivered as specific subjects, the main objective is competence in thecontext of the trade. Therefore, mathematics and science are often integrated directlyinto the theory and shop instruction

The uses of metric and imperial systems of measurement are commonplace throughoutthe industry. Therefore, theory and shop instruction must be arranged so thatapprentices are able to perform completely in both systems

Occupational health and safety requirements are to be an integral part of the trainingprogram

APPRENTICESHIP AND INDUSTRY TRAINING SYSTEM

Apprenticeship is post-secondary education with a difference. It helps ensure NWT has asteady supply of highly skilled employees, the foundation of our economys future health andcompetitiveness.

Apprentices in more than 50 trades and occupations spend between one and four years

learning their trade - 80% of the time on the job under the supervision of a certified journeyperson or qualified tradesperson. The balance of the program is technical training inthe theory, skills and technologies of their trade.

To become certified, apprentices must learn theory and skills, and they must passexaminations. Requirements for certificationincluding the content and delivery of technicaltrainingare developed and updated.

THE NWT APPRENTICESHIP, TRADE AND OCCUPATIONS CERTIFICATION BOARD

The mandate of the NWT Apprenticeship, Trade and Occupations Certification Board relates tothe standards and requirements for training and certification in programs under the

Apprenticeship, Trade and Occupations Certification Act . The Board provides advice to theMinister of Education, Culture and Employment on the training and certification of people indesignated trades and occupations and on the needs of the NWT labour market for skilled andtrained persons. The Board also makes regulations respecting standards and requirements forapprenticeship programs, the training of apprentices, for training and certification in designatedtrades and occupations, and the criteria or requirements for granting and recognizing trade andother certificates.

The 7-member Board consists of a chair, and members representing employers andemployees.

SAFETY EDUCATION

Safe working procedures and conditions, accident prevention and the preservation of healthare of primary importance in apprenticeship programs in NWT. These responsibilities areshared and require the joint efforts of government, employers, employees and the public.Therefore, it is imperative that all parties become aware of circumstances that may lead toinjury or harm. Controlling the variables and behaviours that may contribute to or cause anaccident or injury can create safe learning experiences and environments.

It is generally recognized that a safe attitude contributes to an accident free environment.Everyone will benefit as a result of a healthy, safe attitude towards prevention of accidents.

A tradesperson is possibly exposed to more hazards than any other person in the work forceand, therefore, should be familiar with and apply the Safety Act and Regulations dealing withpersonal safety and the special safety rules applying to each task.
