PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful for people working in local authorities and charged with noise control, as appointed Noise Control Officers. They facilitate the generation of policy, develop procedures, apply the by-laws, ensure that issues between complainants and offenders are resolved, and initiate further action where this becomes necessary, including notices and legal proceedings.

More specifically this standard recognizes the skill and knowledge required to provide input to planning for noise management, as well as advice with respect to noise reduction.

People credited with this unit standard are able to:
  • Demonstrate understanding of transportation noise.
  • Discuss noise prevention and mitigation measures.
  • Provide input to planning to balance environmental, economic and political issues with respect to transportation noise. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

    UNIT STANDARD NOTES 
    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, then focus assessment around each Specific Outcome, or groups of Specific Outcomes.
  • Make sure that 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.

    Terms have been clarified as far as possible through the use of range statements.

    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.
