                                          INTRODUCTION
A.   What is Plumbing about?
Plumbing is the skilled trade of working with pipes, tubing and plumbing fixtures for water systems and the
drainage of waste. Plumbing also refers to a system of pipes and fixtures installed in a building for the
distribution of drinking water and the removal of waterborne wastes. In Plumbing, students acquire the skills
to install sanitary fittings, water piping to buildings and sewerage systems.

B. Why is Plumbing important in the Construction learning programme?
The plumbing industry is a basic and substantial part of every developed economy due to the need for clean
water, and proper collection and transport of wastes. Most building structures require plumbing. Students
interested in careers in the construction industry must be well informed of plumbing principles and requirements.


C. The link between Plumbing Learning Outcomes and the Critical and Developmental Outcomes
In Plumbing, students develop the skill to work in teams and to identify and solve problems. Students also learn to
understand and contribute to the environment by meaningfully interpreting information, which they come across.

Students have the opportunity to develop an understanding of the world as a set of related systems by recognising
the impact that the different environments can have on the construction industry. Students explore educational and
career opportunities in the industry and in important building services


D. Factors that contribute to achieving Plumbing Learning Outcomes
· Thorough preparation for teaching and learning activities
· An environment conducive to teaching and learning through effective learner support, motivation,
  commitment and a positive attitude
· An interest in plumbing
· Exposure to construction environments.

                                                                                  National Certificates (Vocational)




1      DURATION AND TUITION TIME
This is a one-year instructional programme comprising 200 teaching and learning hours. The subject may be
offered on a part-time basis provided the student meets all the assessment requirements.
Students with special education needs (LSEN) must be catered for in a way that eliminates barriers to
learning.

2      SUBJECT LEVEL FOCUS
·     Basic building work for plumbing, including building man holes
·     Install, inspect and maintain below-ground drainage systems
·     Plumbing maintenance and repair work to hot and cold water systems and to waste systems
·     Fabricate and fit box gutters and chimney flashings
·     Installation and maintenance of solar systems

3      ASSESSMENT REQUIREMENTS

3.1        Internal assessment (50 percent)

3.1.1 Theoretical component
The theoretical component forms 40 percent of the internal assessment mark.
Internal assessment of the theoretical component in Plumbing Level 4 takes the form of observation, class
questions, group work, informal group competitions with rewards, individual discussions with students, class,
topic and semester tests and internal examinations. Lecturers can observe students when marking exercises
from the previous day and asking class questions.
Assignments, case studies and tests can be completed at the end of a topic. Tests and internal examinations
must form part of the internal assessment.

3.1.2 Practical component
The practical component forms 60 percent of the internal assessment mark.
Practical components include applications and exercises. All practical components must be indicated in a
Portfolio of Evidence (PoE).
Internal assessment of the practical component in Plumbing Level 4 takes the form of assignments, practical
exercises, case studies and practical examinations in a simulated business environment.
Students may complete practical exercises daily. Assignments and case studies can be completed at the
end of a topic. Practical examinations can form part of internal practical assessment.

· Some examples of practical assessments include, but are not limited to:
      A. Presentations (lectures, demonstrations, group discussions and activities, practical work,
         observation, role-play, independent activity, synthesis and evaluation)
      B. Exhibitions by students
      C. Visits undertaken by students based on a structured assignment task
      D. Research
      E. Task performance in a Structured Environment

· Definition of the term Structured Environment
For the purposes of assessment, Structured Environment refers to a simulated workplace or workshop
environment. Activities in the simulated workplace or environment must be documented in a logbook with a
clear listing of the competencies to be assessed. The following information must be contained in the logbook:
         §    Nature of department or environment in which practical component was achieved
         §    Learning Outcomes
         §    Activities in the environment with which to achieve the Learning Outcomes
         §    Time spent on activities
         §    Signature of facilitator or supervisor and student
For the logbook to be regarded as valid evidence, it must be signed by an officially assigned supervisor.

· Evidence in practical assessments
All evidence pertaining to evaluation of practical work must be reflected in the student s PoE. Assessment
instruments used for the purpose of conducting these assessments must be part of the evidence contained
in the PoE.

3.1.3 Processing of internal assessment mark for the year
A year mark out of 100 is calculated by adding the marks of the theoretical component and the practical
component of the internal continuous assessment (ICASS).

3.1.4 Moderation of internal assessment mark
Internal assessment is subjected to internal and external moderation procedures as set out in the National
Examinations Policy for FET College Programmes.

3.2 External assessment (50 percent)
A national examination is conducted annually in October or November by means of a paper(s) set and
moderated externally. The practical component will also be assessed.
External assessment details and procedures are set out in the Assessment Guidelines: Plumbing Level 4

5            CALCULATION OF FINAL MARK
Internal assessment mark:             Student s mark/100 x 50 = a mark out of 50 (a)
Examination mark:                     Student s mark/100 x 50 = a mark out of 50 (b)
Final mark:                           (a) + (b) = a mark out of 100
All marks are systematically processed and accurately recorded to be available as hard copy evidence for,
amongst others, reporting, moderation and verification purposes.

6            PASS REQUIREMENTS
A student must obtain at least 50 percent in ICASS and 50 percent in the examination to achieve a pass in
this subject.
