    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
  • Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider through the relevant ETQA by SAQA.
  • Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines and the agreed ETQA procedures. 
    		•

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    Essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Candidates are unlikely to achieve all the specific outcomes, to the standards described in the assessment criteria, without knowledge of the listed embedded knowledge. This means that for the most part, the possession or lack of the knowledge can be directly inferred from the quality of the candidate's performance. Where direct assessment of knowledge is required, assessment criteria have been included in the body of the unit standard.

    The embedded knowledge required for this unit standard is found in Specific Outcome 1.

    Terminology:

    Specified requirements:

    Specified requirements include legal and site-specific requirements and are contained in one or more of the following documents:
  • Legal:

    > Relevant Acts: e.g. Mine Health & Safety Act, 1996 (Act no 29/1996), and Minerals Act and Regulations, 1991 (Act no 50/1991)
    > Mandatory Codes of Practice
    > SABS and other relevant Standards
    > Chief Inspector of Mines' Directives
  • Site specific:

    > Hazard Identification and Risk Assessments (HIRA)
    > Occupational Health and Safety Risk Management Programme
    > Managerial Instructions
    > Mine Standard Procedures
    > List of Recorded OH&S Risks
    > Working Guides
    > Equipment and Materials Specifications

    Notes to assessors:

    Assessors should keep the following principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the candidate is able to perform in the real situation.
  • Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The assessment criteria provide the specifications against which assessment judgements should be made. In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques. Where this is required, there will be assessment criteria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the candidate can achieve the outcomes again and again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: appropriateness, fairness, manageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent.

    Unit standard justification:

    Level:
  • Attribute: Skills; Level: 2; Justification: The skills that are required show some variety, but are still fairly simple.
  • Attribute: Procedures; Level: 2; Justification: Although the procedure is known and familiar (as in Level 1), it is not as repetitive.
  • Attribute: Context; Level: 2; Justification: Although the process could occur in different contexts, these contexts are repeatedly applicable and known to the candidate.
  • Attribute: Knowledge; Level: 2; Justification: The knowledge that is required is related to the operation and no theory therefore needs to be applied.
  • Attribute: Information processing; Level: 2; Justification: Information is readily available but some processing is required.
  • Attribute: Problem solving; Level: 2; Justification: A degree of judgement has to be applied.
  • Attribute: Orientation of activities; Level: 3; Justification: Instructions are to be followed, but there is some autonomy to make own decisions and hand down instructions.
  • Attribute: Orientation of scope of responsibility; Level: 2; Justification: Candidate has some responsibility for quantity and quality.
  • Attribute: Application of responsibility; Level: 3; Justification: Candidate's output is checked for quality on a random basis.
  • Average level: 20/9 = 2.2
  • Actual level assigned: 2

    Credits:

    Total hours required by the learner to achieve the required outcome:
  • Activity: Classroom teaching; Hours: 10
