    UNIT STANDARD NOTES 
    This unit standard has been replaced by unit standard 243081, which is "Cut material using the oxy-fuel straight-line cutting machine", Level 3, 3 credits.

    This prior learning may be assessed through RPL, and can be used by the learner to make it easier to obtain the outcome of this Unit Standard.

    Supplementary Information:

    Assessment methods:
    Integrated assessment methods and tools will allow the candidate to demonstrate that she/ he has acquired knowledge of and can safely and effectively apply competence identified in this unit standard. These tools may include the following:
  • In-situ (on-the-job) observations
  • Role-play simulations
  • Structured group discussions
  • Written reports (e.g. tests, exams, case studies, projects, registers, logbooks, workbooks)
  • Verbal report backs (presentations)
  • Portfolios of evidence
  • Projects (physical visits to Government Departments)
  • Experiential learning
  • Working in teams
  • Scenario sketching
    These methods must be carefully selected based on the purpose of the assessment (For example, the written method of assessing knowledge or on-job demonstration of practical competence). The assessment must integrate a number of different methods in order to give the assessor reliable and valid proof of competence and evidence of required attitudes.

    Supplementary Material

    ISO 5817 (Visual Inspection).
    Resource material related to this cutting process.

    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 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 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.

    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.
