UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS

1. Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.

2. Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider through the relevant ETQA by SAQA.

3. Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines and the agreed ETQA procedures.

UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE

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.

The following embedded knowledge is addressed in an integrated way in the unit standard:

Health and safety knowledge.

Report writing.

Legal and site-specific requirements.

Critical Cross-field Outcomes (CCFO):

UNIT STANDARD CCFO IDENTIFYING

Identify and solve problems and make decisions using critical and creative thinking.

Note: The ability of the candidate to achieve and maintain mining stability with support.

UNIT STANDARD CCFO WORKING

Work effectively with others as members of a team, group, organisation or community.

Note: The ability and willingness of the candidate to accept and interpret work instructions correctly and to request assistance with support installation in an appropriate manner as a member in the bigger organisational structure.

UNIT STANDARD CCFO ORGANISING

Organise and manage themselves and their activities responsibly and effectively.

Note: The preparation for support installation must indicate that the candidate can organise and manage activities in his/her work environment.

UNIT STANDARD CCFO COLLECTING

Collect, analyse, organise and critically evaluate information.

Note: The ability to recognise changing ground conditions and has knowledge of the appropriate action to take. The candidate must be able to interpret and apply mine standards.

UNIT STANDARD CCFO COMMUNICATING

Communicate effectively, using visual, mathematical and / or language skills in the modes of oral and / or written presentations.

Note: The appropriate communication with the relevant personnel with regard to the reporting of hazardous and sub-standard conditions will indicate his/her proficiency in effective communication.

UNIT STANDARD CCFO SCIENCE

Use science and technology effectively and critically showing responsibility towards the environment and health of others.

Note: The use of mechanised equipment and support types as well as consideration of a variety of types indicates effective use of science and technology.

UNIT STANDARD CCFO DEMONSTRATING

Demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation.

Note: The ability of the candidate to identify hazardous conditions. The effect of non-compliance and deviation from mine standards will indicate his/her proficiency in understanding that a specific action or decision taken has more than one effect.

UNIT STANDARD ASSESSOR CRITERIA

Assessors should keep the following 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, 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.
