PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful to people who work on a concrete construction site and are required to batch and mix concrete by volume.

People credited with this unit standard are able to:
  • Prepare to mix concrete
  • Measure and add materials to the concrete mix
  • Mix and load the concrete, and
  • Conduct post mixing activities

    Previously disadvantaged persons and other learners who through recognition of prior learning will be able to be accessed against this standard and receive National recognition for their competence. This will enhance their employability and career advancement and contribute to the socio-economic transformation of the country. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    Assessment of learner achievements takes place at providers accredited by CETA (RSA, 1998b) for the provision of programs that result in the outcomes specified for the Certificate for Construction Workers. CETA is responsible for moderation of learner achievements of learners who meet the requirements of this qualification.

    A memorandum of understanding with other ETQA bodies need to be signed when training providers working in other Sectors, requires assessment of learner achievements to take place against this unit standard. 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    The following 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.

    Qualifying learners understand and can explain:
  • The identification and use of protective clothing when working with cement and aggregates.
  • The identification and selection of materials from stockpiles.
  • The volumetric measurement of materials to be added to the mix.
  • The consequences of incorrect quantities.
  • The correct addition of water.
  • The cleaning of equipment after mixing. 
    		•

    UNIT STANDARD ASSESSOR CRITERIA 
    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 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: The method of assessment is suited to the performance being assessed
  • Fairness: The method of assessment does not present any barriers to achievements, which are not related to the evidence
  • Manageability: The methods used make for easily arranged, cost-effective assessments that do not unduly interfere with learning
  • Integration into work or learning: Evidence collection is integrated into the work or learning process where this is appropriate and feasible
  • Validity: The assessment focuses on the requirements laid down in the Standard; i.e. the assessment is fit for purpose
  • Direct: The activities in the assessment mirror the conditions of actual performance as closely as possible
  • Authenticity: The assessor is satisfied that the work being assessed is attributable to the person being assessed
  • Sufficient: The evidence collected establishes that all criteria have been met and that performance to the required standard can be repeated consistently
  • Systematic: Planning and recording is sufficiently rigorous to ensure that assessment is fair
  • Open: Learners can contribute to the planning and accumulation of evidence. Assessment candidates understand the assessment process and the criteria that apply
  • Consistent: The same assessor would make the same judgement again in similar circumstances. The judgement made is similar to the judgement that would be made by other assessors
