    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners have achieved the equivalent of NQF Level 4 in a formal education environment.

    Recognition of Prior Learning:

    The structure of this qualification makes the Recognition of Prior Learning possible. This qualification may therefore be achieved in part or completely through the recognition of prior learning, which includes formal, informal and non-formal learning and work experience. The learner should be thoroughly briefed on the mechanism to be used and support and guidance should be provided. Care should be taken that the mechanism used provides the learner with an opportunity to demonstrate competence and is not so onerous as to prevent learners from taking up the RPL option towards gaining a qualification.

    If the learner is able to demonstrate competence in the knowledge, skills, values and attitudes implicit in this qualification the appropriate credits should be assigned to the learner. Recognition of Prior Learning will be done by means of Integrated Assessment as mentioned above.

    This Recognition of Prior Learning may allow:
  • Accelerated access to further learning at this or higher levels on the NQF.
  • Gaining of credits towards a unit standard.
  • Obtaining of this qualification in part or in whole.


    Access to the Qualification:

    There is open access to the qualification. However, it is preferable that learners should acquired language competencies and mathematical literacy competencies at NQF Level 4.

    Integrated Assessment appropriately incorporated to ensure that the purpose of the qualification is achieved:

    Assessment practices must be open, transparent, fair, valid, and reliable and ensure that no learner is disadvantaged in any way whatsoever.

    This qualification is comprised of the following:
  • Practical competences: What a candidate must be able to do.
  • Knowledge requirements: What a candidate must know.

    There are several ways in which these can be assessed:

    Practical:

    Assessors may be required to use different assessment methods:
  • Competence checklist: Observation of performance.
  • Competence checklist: Appraisal of a product.
  • Practical assignment.

    Knowledge requirements:

    Learners will be required to take tests to show that they meet the knowledge requirements.

    These assessments can take the following forms:
  • Written tests: Multiple choice.
  • Written tests: Short, structured questions.

    Learning, teaching and assessment are inextricably interwoven. Whenever possible, the assessment of knowledge, skills, attitudes and values shown in the modules will be integrated.

    Assessment of communication, language, literacy and numeracy should be integrated as far as possible with other aspects and should use practical contexts wherever possible.

    Where it is not possible to assess the learner in the workplace or on-the-job, simulations, case studies, role-plays and other similar techniques such as realistic working environment including real work timescales and pressures should be used to provide a context appropriate to the assessment.

    During integrated assessments the assessor should make use of formative and summative assessment methods and assess combinations of practical, applied, foundational and reflexive competencies.

    All learners are required to complete an externally set and marked international examination in order to achieve the qualification.

    Assessment should ensure that all outcomes and critical cross-field outcomes are evaluated.
