Assessment outcome 30


INSTRUCTIONS TO ASSESSORSTo prepare for assessment of this unit of competency, assessors should refer to the RII Assessment Materials Overview Guide. This guide includes directions on how to conduct an assessment for Recognition of Prior Learning (RPL).

Prepare for the theory assessment • Ensure date, time, place, employee, assessment instrument and any tools/equipment are arranged.

• Ensure the environment is adequate for delivery of assessment, eg by computer, pen-and-paper or orally.

• The assessment questions have been drafted for easy conversion into a computer-based questionnaire.

• Where English or computer literacy is an issue for the employee, the employee can be offered support eg an oral assessment can be conducted.

• The theory assessment has been drafted as a bank of assessment questions from which a suitable set of sample questions should be chosen for any one assessment.

• When a sample of assessment questions is chosen from the complete bank of items, ensure the items have been suitably selected (eg all areas of the job role have sufficient sample questions included; all sections of the assessment have representative questions included) and the assessment form is finalised for the employee to use (whether in computer, pen-and-paper or oral format). Issues of question selection and coverage are decided according to site policy.

• Gather relevant site standards and procedures from the appropriate authorised company personnel.

• Explain what is required of the employee. Both employee and assessor must confirm the employee’s readiness for assessment. It is recommended that the theory assessment is completed before the practical assessment.

• Advise the employee of performance requirements for “Satisfactory” performance, according to site policy.

Customising the assessmentThe assessment questions should be customised to reflect site-specific:

• risks and hazards

• equipment and machinery

• processes and procedures, including reporting and recording procedures

• standards and requirements

Safety • Ensure all personnel have completed an area-specific induction prior to assessment commencing.

• Site, area and statutory safety requirements must be observed at all times.

• All Personal Protective Equipment (PPE) appropriate to the area the assessment is being carried out in, is to be worn at all times.

Carrying out the assessment • Gather evidence of the employee’s learning using this theory assessment tool.

• Questions may be asked of the assessor during the assessment on any concerns relating to the assessment process and/or to clarify questions.

• To gain overall competency in the unit, both the theory and practical assessment criteria must be met. All questions must be answered correctly, unless otherwise stated in the assessment instrument or unless site policy has other specific requirements for “Satisfactory” performance.


Completing the assessment • Prior to the theory assessment, the Theory Pre-Assessment form should be completed by the employee and

assessor. The right of appeal under the company fair treatment policy (or equivalent) should be explained.

• All sections of the assessment must be completed with an ink pen for a paper or oral assessment, or on a suitable computer as demonstrated by the assessor.

• On completion of this assessment the employee should sign the Theory Assessment Summary.

• Communicate to employee any feedback comments.

Assessment Conditions • An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry

regulations for certification and licensing; and,

• this unit is best assessed in the context of this sector’s work environment;

• where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills; and,

• this unit must be assessed using Resources and Infrastructure Industry sector specific policies, procedures, processes and operational manuals; and,

• assessor requirements differ between sectors as follows:

• when assessing this unit in the context of the Drilling sector:

• an assessor must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through five (5) years of work in the Industry sector; or,

• where a co-assessment or partnership arrangement exists between a qualified assessor and an Industry technical expert, the Industry technical expert can hold the unit being assessed, and/or demonstrate equivalency of skills and knowledge at the unit level. An Industry technical expert must also demonstrate a minimum of three (3) years of continuous work in the Industry sector, with the preceding one (1) year in the unit they are co-assessing; or,

• when assessing this unit in the context of the Metalliferous Mining sector:

• an assessor must demonstrate the skills and knowledge of this unit through five (5) years of current and continuous work with the Industry sector and must hold the TAE Assessor Skill Set or equivalent; or,

• when assessing this unit in the context of the Coal Mining sector:

• an assessor must demonstrate the skills and knowledge of this unit through twelve (12) month work experience in an Industry relevant to the skills being assessed within the last three (3) years; and,

• where the assessor does not have current experience a co-assessment or partnership arrangement needs to exist between the qualified assessor and an Industry technical expert/ subject matter expert. The Industry technical expert/subject matter expert must demonstrate competency in the unit being assessed, and be currently working in the sector with a minimum of twelve (12) months’ work experience within the last three (3) years; or,

• when assessing this unit in the context of the Extractive sector:

• an assessor must demonstrate the skills and knowledge of this unit through five (5) years’ work experience in the Industry sector; and,

• where the assessor does not have current experience a co-assessment or partnership arrangement needs to exist between the qualified assessor and an Industry technical expert/ subject matter expert. The Industry technical expert/subject matter expert must hold the unit being assessed and be currently working in the sector with a minimum of two (2) years’ of current work experience; or,


• when assessing this unit in the context of the Civil Construction sector:

• an assessor must demonstrate the skills and knowledge of this unit through five (5) years’ work experience in the Industry sector; and,

• where the assessor does not have current experience a co-assessment or partnership arrangement needs to exist between the qualified assessor and an Industry technical expert/ subject matter expert. The Industry technical expert/subject matter expert must hold the unit being assessed and be currently working in the sector with a minimum of two (2) years’ of current work experience.
