Produce fibrous plasterboard

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency applies to operators who are responsible for the manufacture of fibrous plaster sheeting using a mixture of plaster material and fibre. Operators produce much of the product by hand with the full sheets cut to length after the product has set.

Generally the operator would be part of a team during the process and at all times they would be liaising and cooperating with other members of the team.

This unit of competency covers the production of fibrous plasterboard. It involves facilitating the mixing operation, ensuring plaster is of the correct consistency and formulation, maintaining a clean work environment, manually combining the fibre and plaster, cutting sheets to size and turning out sheets to facilitate final curing.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

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

It is essential that the equipment be understood and that the importance of critical material properties, settings and readings is known.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

work area is maintained appropriately

plaster is mixed to required consistency

plasterboard is formed correctly

finished product meets required dimensions

all OHS requirements are followed

problems are anticipated and appropriate action is taken (i.e. problem fixed or reported).

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

recognising process conditions which will lead to out of specification production and taking appropriate action

implementing enterprise's standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of the melting equipment

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

composition and nature of materials being utilised

equipment startup and shutdown processes

drying times and conditions

out of specification situations

distinguish between causes of faults such as:

incorrect raw materials

equipment maladjustment

contamination or poor maintenance

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Procedures

All operations are performed in accordance with standard procedures and work instructions

Equipment

Equipment may include:

mixers

moulds or formers

lifting equipment

cutting equipment

drying and other equipment integral to the manufacture of fibrous plasterboard

Fibre

Fibre may include:

glass fibre or other appropriate fibre

Typical problems

Typical problems may include:

inappropriate material specifications

introduction of contaminants

inclusion of air

distortion or section thickness variations

Occupational health and safety (OHS)

The identification and control of hazards and the application of OHS are to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist
