    UNIT STANDARD NOTES 
    Comment on this unit standard should reach SAQA no later than 26 October 2007.
    The level assigned to this unit standard is appropriate because the learner:
  • Has basic knowledge of some main areas of a discipline/field.
  • Has basic understanding of a discipline/field's key term, rules, concepts, principles and theories.
  • Is familiar with some of the essential methods, procedures and techniques of the discipline/field.

  • Has the ability to communicate information reliably and accurately in the required medium of instruction.
  • Has the capacity to operate within clearly defined contexts, with limited scope for personal decision-making and responsibility.
  • Learn within a well-structured and managed environment.
  • Evaluate own performance against given criteria.

    Legal Requirements:

    Compliance to the following legal requirements and standards are mandatory:
  • Employer's Policies and Procedures.
  • Environmental Management System.
  • Independent Communications Authority of South Africa.
  • Occupational Health and Safety Act.
  • National and International Standards.
  • Local Metropolitan Council Regulations.

    Notes to Assessors:

    Assessors should keep the following general 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 and then focuses 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. Ensure that 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 judgments 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.
  • Requirements for a portfolio are that it should be valid, reliable and authentic evidence (presented as a portfolio of evidence) from past achievements and experience, which serves to supplement the assessment of applied competence.

    The portfolio may include:
  • Written statements from persons (e.g. current and/or previous employer, colleague, peer, manager, external customers) confirming competence of the learner.
  • Relevant certificates or awards.
  • Previous assessment records.
  • Journals/logbook.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
