PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard in combination with context expertise standard(s) will be able to assist in the operation of a sand filter. This competence will enable the learner to explain rapid gravity and slow sand filters and operate one type of sand filter. This will contribute towards the water purification process and maintain the quality of potable water available to consumers. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
Numeracy NQF level 1, Literacy NQF level 1, personal safety practices. 

UNIT STANDARD RANGE 
Safety equipment:

Overalls, gloves, gumboots, safety shoes. 

Specific Outcomes and Assessment Criteria: 

SPECIFIC OUTCOME 1 
Prepare for shift take over 

ASSESSMENT CRITERIA 

ASSESSMENT CRITERION 1 
1. Instructions and information needed for shift take-over are obtained. 
ASSESSMENT CRITERION NOTES 
Integrated Assessment:

When conducting assessments, assessors must ensure that they are familiar with the full text of the unit standards being assessed. Assessors must ensure that the assessment covers the specific outcomes, critical cross-field outcomes and essential embedded knowledge by developing assessment activities and tools, which are appropriate to the contexts in which the learners are working. These activities and tools may include self-assessment, peer assessment, formative and summative assessment. It may be more effective and efficient to assess a number of unit standards together in an integrated way, thus reducing the overall number of assessments and ensuring that commonalities that exist among a number of unit standards are captured in a way that makes sense for assessment.

Assessment Option:

Learners could be assessed using the following methods:
  • Oral or written questions
  • Observation
