In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This qualification does not replace any other qualification and is not replaced by any other qualification. 

PURPOSE AND RATIONALE OF THE QUALIFICATION 
People who achieve this qualification will be recognized for their ability to calculate the size of air-conditioning, refrigeration and ventilation plants for specific purposes, select the equipment and distribution systems required for these plants and compile the required technical documentation.

Qualifying candidates will be able to practice in the air-conditioning, refrigeration and ventilation industry as technicians in the engineering, manufacture, installation and maintenance contexts.

Candidates may choose to specialize in air-conditioning and ventilation or refrigeration.

Rationale:

This is the fourth and last qualification in a series for learners following a career in air-conditioning, refrigeration and ventilation. This is a growth industry and there is a demand for workers with technical skills for manufacturing, installation, maintenance and repair of equipment.

For those who have been active in the industry for a period of time, this qualification represents part of the RPL process to acknowledge skills acquired without the benefit of formal education or training.

The qualification also forms the basis for further development and has been designed to articulate directly to learning programmes and qualifications in air-conditioning, refrigeration and ventilation at Pr.Tech, B. Tech and higher levels 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
This qualification assumes that the candidate has already achieved a National Certificate in air-conditioning, refrigeration and ventilation at NQF level 4.

In particular, the following learning is assumed to be in place prior to embarking on learning towards this qualification
  • Literacy and numeracy
  • Concepts of science and technology
  • Concepts of business and the economy
  • Concepts in workplace relationships, procedures, roles and responsibilities

    Recognition of prior learning:

    Whether a candidate attends formal courses or acquires the required skills through informal means, the same standards apply as per the matrix of unit standards. The qualification and the standards have been written in such a way that the learning has to be assessed in an integrated way. Assessors will assess evidence to establish what the learners know and can do. Such evidence may be gathered through course related activities or through work related activities.

    In cases where candidates do not attend formal courses, assessors should seek work related evidence as far as possible.

    Where courses are provided for learners, institutions can use the unit standards and this qualification to assess learning achievements.

    For candidates who are not able to achieve the outcomes, providers can then use the standards and qualification to determine a specific learning programme to suit the candidate's learning needs.

    QUALIFICATION RULES 
    Fundamental: 29 credits
    Core: 91 credits
    Elective:
    Candidates have a choice of specialising in air-conditioning and ventilation or refrigeration. They are required to accumulate a minimum of 40 credits in the elective unit standards.

    A total of 240 credits are required for the National Diploma. 160 credits must be obtained from NQF level 5, balance can be obtained from approved NQF level 4 unit standards. 

    EXIT LEVEL OUTCOMES 
    Exit Level Outcomes:
  • Compile electrical power and control diagrams for air-conditioning, refrigeration and ventilation plants.
  • Calculate the cooling and heating requirements for plants
  • Calculate sizes for interconnecting piping and ducting systems
  • Select equipment for air-conditioning, refrigeration and ventilation plants.
  • Calculate plant operating costs
  • Compile specifications, operating and commissioning manuals for plants

    The qualification also addresses the following Critical Cross-Field Outcomes:
  • Identify and solve problems and make decisions using critical and creative thinking
  • Work effectively with others as members of a team, group, organization or community
  • Organize and manage themselves and their activities responsibly and effectively
  • Collect, analyze, organize and critically evaluate information
  • Communicate effectively, using visual, mathematical and/or language skills in the modes of oral and/or written persuasion
  • Use science and technology effectively and critically showing responsibility towards the environment and health of others
  • Demonstrate an understanding of the world as a set of related systems by recognizing that problem-solving contexts do not exist in isolation 
    		•

    ASSOCIATED ASSESSMENT CRITERIA 
    Integrated Assessment:

    Assessors will require evidence of competence in terms of each unit standard indicated in the matrix of unit standards required for this qualification. The assessment criteria for each unit standard will serve as the standard against which assessors must make their assessment judgments. When assessors are satisfied that the criteria have been met for each unit standard, assessors must ensure there is sufficient evidence of the ability to integrate the full range of skills required in order to commission, fault find and maintain air-conditioning and ventilation or refrigeration plants and systems.

    This evidence could be collected through:
  • Observations in a simulated environment
  • Observations during work or participation in work related activities
  • Questions designed to test understanding and knowledge in terms of each unit standard's requirements, and the ability to integrate at qualification level.
  • Records and reports compiled as part of assessment portfolios.
    Moderators will check integration of all assessments at qualification level. This could include observing individual assessment.

    This qualification compares favourably with the following international qualifications:

    ARTICULATION OPTIONS 
    N/A 

    MODERATION OPTIONS 
    Moderation of assessments must take place whenever assessments are carried out at qualification level. Moderators must also be accredited for the particular sub-field or have knowledge and experience of air-conditioning or refrigeration. 

    CRITERIA FOR THE REGISTRATION OF ASSESSORS 
    Assessors will have to be registered as assessors by the relevant ETQA in line with SAQA's registration requirements. In terms of assessment expertise, assessors will need to provide competence in line with the unit standards for assessors.

    In terms of technical expertise, assessors will need to demonstrate evaluative ability in relation to the unit standards they assess. By evaluative ability is meant the assessor need not necessarily have the psych-motor skills needed to achieve each unit standard they assess themselves, but that knowledge and experience that enables them to make fair, valid and reliable judgments of the candidates ability relative to the unit standard at hand. 

    NOTES 
    The assessment criteria for each unit standard are to be used by the assessor as the basis for assessment judgments, first in relation to each unit standard, and then in relation to integration at exit outcome level.
