Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can:

conduct site and laboratory operations, and analyse test results and observationsto assign a site classification

read and interpret maps, drawings, specifications and codes of practice

conduct subsurface explorations and log strata

conduct insitu testing for site classification purposes

conduct disturbed and undisturbed sampling

record project details in writing, by sketching and photography

conduct laboratory testing for site classification purposes

observe, interpret and report atypical situations

communicate problems to appropriate personnel

report results to clients using enterprise procedures.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

MSL915001A Provide information to customers

MSL916003A Supervise laboratory operations in work/functional area.

Resources may include:

access to building sites, site tools, equipment and materials

standard construction materials testing laboratory, samples, equipment, materials, test methods and enterprise procedures

access to more than one workplace or simulated learning environment if the primary workplace or learning environment is unable to provide a suitable range of equipment.

Method of assessment

It is strongly recommended that assessment is conducted through observation over time. The timeframe must allow for adequate assessment of operation under all normal and a range of abnormal conditions. Where this is not practical, additional assessment techniques must be used.

The following assessment methods are suggested:

review of site classifications and other enterprise documentation prepared by the candidate

analysis of work completed over a period of time to ensure accurate and consistent work is obtained within required timelines

feedback from peers and supervisors

use of suitable simulation and/or a range of case studies/scenarios.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment.

This competency in practice

Industry representatives have provided the case study below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Construction materials testing

A geotechnical consultancy company has been contracted to perform a site investigation for the purpose of determining the classification of a building site. The client is a structural engineer who will use the information to design a block of townhouses for the site. The company manager assigns a senior technician to the project along with an experienced tester to perform the site work. A second tester will perform the laboratory testing. The senior technician is a signatory for all tests for which the organisation is NATA accredited. They obtain a map of the area and establish that there is no local information available on conditions in the immediate vicinity. There are no buried services to be damaged during the investigation. They brief the field tester on the project, specifying the number and suggested locations of boreholes as well as the sampling and testing requirements. The field tester performs the site investigation by drilling power auger holes, logging and sampling the strata and performing dynamic cone penetrometer (DCP) tests. They push tubes to obtain undisturbed samples of material that they classify as high plasticity clay. They note the presence of uncontrolled fill in one corner of the site, and take several photographs with a digital camera.

When the site investigation is completed, the senior technician inspects the field logs, notes and photographs and then specifies an appropriate testing program, including shrink-swell tests on the high plasticity clay. Using the shrink-swell test result, they calculate the characteristic surface movement and after reviewing all the data assign a P classification in accordance with AS2870: Residential slabs and footings - Construction. They then prepare a report to the client, including a description of the site, the extent and nature of the investigation, test results and bore logs and the site classification. Finally, all documentation relating to the project is filed and stored as a complete record in accordance with NATA, quality assurance and liability requirements. After review by the company manager, the results of the investigation are communicated to the client.
