to obtain a Government Certificate of Competency.
- The following instructions, rules and syllabi for the
examinations set by the Commission of Examiners are constituted in
terms of the Occupational Health and Safety Act, 1993 and the
Regulations concerning the Certificate of Competency, 1990.
- The following Certificates of Competency are issued by the
Department of Labour:
(a) Certificate of Competency as Mechanical Engineer (Factories).
(b) Certificate of Competency as Electrical Engineer (Factories).
- Written examinations for each of these certificates are held in
June and November by the Department of Education in collaboration
with the Commission of Examiners appointed by the Chief Inspector.
- The procedure to be followed in order to acquire a Certificate
of Competency is summarised below.
Top
- To qualify for a Certificate of Competency as Mechanical or
Electrical Engineer, the following subjects must be passed by
persons accepted as candidates:
(a) Plant Engineering (Factories) (b) Occupational Health and Safety Act, 1993, and the regulations
promulgated there under.
- To qualify for a Certificate of Competency, candidates must
obtain at least 50% of the full marks in each subject stipulated at
least in 2.1. Candidates need not pass both subjects at the same
examination sitting, but the second subject must be passed within 3
years of passing the first, otherwise both subjects must be
re-written. However, if a candidate obtains 75% or more of the full
marks in either subject, he will be permanently exempt from
re-writing that subject. An appropriate certificate of competency
will be issued to candidates who have passed both subjects.
Top
- No person shall be allowed to write the qualifying examinations
unless accepted as a candidate by the Commission of Examiners. No
credit will be given for a pass in the subjects mentioned in 2.1
before acceptance.
- An applicant shall not be accepted as a candidate by the
Commission of Examiners unless he has submitted proof that he has
reached the age of 23 years, of his sobriety and general good
conduct and that he is in possession of one of the following
qualifications with appropriate experience in engineering:
- A B.Sc. degree in mechanical or electrical engineering
recognised by the Commission of Examiners and at least 2 years post
graduate experience in the maintenance and operation of mechanical
or electrical machinery, as the case may be, which is to the
satisfaction of the Commission of Examiners.
- A National Higher Diploma (T4) or National Diploma (S4) in
mechanical or electrical engineering, (Technikon course) plus at
least 2 years subsequent experience in the maintenance and operation
of mechanical or electrical machinery, as the case may be, which is
to the satisfaction of the Commission of Examiners, and of which at
least one year has been at a factory. The completion of such course
shall include passing all the subjects with a mark of as least 50%.
- Individual Technikons will structure a curriculum to cover the
electrical and mechanical courses according to the requirements of
the Plant Engineering Syllabus.
- The Technikon will subsequently certify that a candidate for the
Government Certificate of Competency having followed the Technikon
route, has:
(i) completed a curriculum which covers the syllabus for Plant
Engineering (ii) acquired a National Higher Diploma (T4) or National Diploma
(S4) with a mark per subject of at least 50%; and (iii) received the necessary practical training, to obtain the
National Higher Diploma (T4) or National Diploma (S4).
- A National Technical N6 diploma in mechanical or electrical
engineering (Technical College Course). The completion of such a
course will include passing all the subjects with a mark of at least
50%. A person will also have served an apprenticeship in an
appropriate trade and gained experience in the maintenance and
operation of mechanical or electrical machinery, as listed.. Such experience, of which at least one year has been at a
factory, shall be to the satisfaction of the Commission of
Examiners.
- The Department of Education will structure a curriculum to cover the
electrical and mechanical course according to the requirements of
the Plant Engineering Syllabus as set out. After completion of the prescribed courses the
candidate should have:
(i) completed the curriculum which covers the syllabus for Plant
Engineering; and (ii) acquired a National Technical Certificate with a mark of at
least 50% in all the subjects.
- A candidate who is in possession of the necessary qualifications as
listed will be evaluated and accepted accordingly.
- Other qualifications and experience will be considered on merit
by the Commission of Examiners
- Persons who wish to be accepted as candidates and who are in
possession of a foreign degree, diploma or certificate in
engineering, or who are in possession of engineering qualification
other than those mentioned in 3.2, must have such a degree, diploma,
certificate or engineering qualification evaluated by the Department
of Education, Engineering Field of Study, Private Bag X110,
Pretoria, 0001, or who will indicate what additional subjects, if
any, must be passed in order to comply with the requirements for
acceptance. A request for evaluation must indicate that it is for
the Certificate of Competency (M) or (E), and must include a list of
the subjects, including marks obtained, which led to the obtaining
of the degree, diploma, or certificate. A copy of the evaluation and
a certified copy of the degree, diploma or certificate must
accompany the application for acceptance as a candidate.
NOTE: An evaluation by the Human Science Research Council or South
African Qualifications Authority on its own is NOT sufficient.
- A person who has been accepted by the Commission of Examiners as
a candidate and did not obtained a Certificate of Competency within
seven (7) years from the date of his/her acceptance must re-ply to
the Commission for acceptance.
