4 Assessor Guidelines General 1. Introduction 1.1 Scope These general guidelines apply to all the assessment instruments for the certificates of competency prescribed by the National Guidelines for Occupational Health and Safety Competency Standards for the Operation of Loadshifting Equipment and Other Types of Specific Equipment. (NOHSC: 7019) Assessors should also be famil iar with the publication Assessment guidelines for National Occupational Health and Safety Certification Standard for users and operators of industrial equipment. 1.2 Additional Guidelines Guidelines that provide additional specific information to certificate assessors are also included in each assessment instrument. Included, where appropriate, are specific instructions on the usefulness of training records (such as logbooks) and other certificates with overlapping competencies. 1.3 Evidence of Competence Eviden ce of competence is established in a number of ways. The methods used in the following instruments involve: Assessment of practical performance Written and/or oral answers to questions on underpinning knowledge 2. Preparing for the Assessment 2.1 Study the instruments You need to read the assessment instruments and specific instructions carefully before beginning an assessment 2.2 Confirm Appointments Prior to the assessment, you need to confirm the date, time and location of the assessment with the applicants and any other relevant people. 2.3 Equipment Availability The availability of equipment, materials and a suitable working area must be organised and confirmed, prior to the assessment 2.4 Workplace Factors Because procedures and processes vary greatl y between workplaces, it is important for assessors to plan their approaches to meet the requirements of the individual workplace. Make sure you take the timeframe into account when planning the assessment and also make applicants aware of any time limits . 2.5 Selecting Questions Questions for the written/oral assessment should be randomly selected, either by hand or using the computer system, if applicable. 3. Conducting the Assessment 3.1 Provide an Explanation Begin by explaining clearly to the applicant wh at is required of them. Check that applicant has provided (or has been provided with) the necessary tools and equipment. 3.2 Practical Performance Complete the practical performance checklist, as the applicant works through the required tasks. Wherever possible, this should be done in a normal working environment. Do not ask the applicant questions while he/she is performing a task, as this can be distracting, and may affect the time taken to complete the assessment.

5 If, at any time, the applicant is en dangering themself or others, stop the assessment immediately. This indicates that the applicant is not yet competent and may require further training, before been reassessed. Assessments should also be stopped, if equipment or property is likely to be da maged. 3.3 Knowledge The oral/written assessment pinning knowledge. The model answers provided with the oral/written assessment instruments are not necessarily exhaustive. Use your own judgement when scoring alternative answer s. 3.4 Recording Responses A box accompanies each item and question on the assessment forms you use. Assessors must complete every box as follows: CORRECT PERFORMANCE/ANSWER N OT YET ACHIEVED NOT APPLICABLE If a box is marked incorrectly, cross out the mistake, mark the correct response alongside, and initial the change. 4. Determining Competencies 4.1 Assessment Summary A specific assessment summary is given for each certificate class. This is to be filled in and signed by the assessor and counter signed by the applicant. Notice of Satisfactory Assessment the original and duplicate are given to the applicant. The applicant provides the original to the certifying authority. The assessor retains the triplicate. 4.2 Competency Re quirements In order for you to deem an applicant competent, he or she must have completed each section of the assessment to the standard required. You should note any time constraints when arriving at your decision. The standard required for each instrume nt is specified in the specific guidelines and/or on the summary page at the end of each instrument. In the case of a re – assessment, the assessor can decide to apple the whole or only that part of the assessment not yet achieved. 4.3 Additional Comments Wher e an applicant fails to meet the standard of competence, you should add a written comment on the Assessment Summary, which briefly explains the problem. Advice to the applicant, on the appropriate remedial action should also be included. This will also as sist the certificate assessor, in an event that the applicant undergoes future reassessment. 4.4 Further Investigation As a certified assessor, it is your role to determine whether or not an applicant has achieved the standard necessary for the certifying Aut hority to be able to grant a certificate of competency. Whenever you are unsure of the knowledge, ask additional questions, and obtain additional evidence, before making your final decisions. X NA

8 Assessors Note: All performance criteria marked with a star are compulsory/critical. To determine a performance criteria, a prescribed number of elements are required to be demonstrated/answered under that criteria. The applicant must achieve the minimum specified number or more, of the performance elements to achieve competence for those criteria. for the criteria a tick must be placed i n the star. 10. informed of the reason(s) in order to gain further appropriate training. 11. The full performance assessment can take up to 1 hour. 12. The general assessment requirements are set out in Assessor guidelines general . 13. Competence is achieved for a unit when the required number of elements for that unit have been correctly performed and ticked. 14. Overall competence is achieved when competence in all units has been achieved. 15. Where a p erformance element cannot be performed the assessor can stimulate or ask a question. The response must be recorded.
