Version 1.0
Issue Date: March 2024


This competency normally applies to the individual who is required to conduct explosive material tests and/or experiments in an explosive ordnance research environment.

This unit encompasses the requirements for planning the tests or analyses, carrying out tests and measurements, performing quantitative and qualitative analysis, documenting and evaluating new procedures, and recording and validating the test results.

This unit covers the competency required to conduct explosive material tests and/or experiments in an explosive ordnance research environment.

This unit covers the application of procedures to conduct explosive material tests, planning the tests or analyses, carrying out tests and measurements, performing quantitative and qualitative analysis, documenting and evaluating new procedures, and recording and validating the test results.

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

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, the Range Statement and the Assessment Guidelines for this Training Package.

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

Assessment must confirm the ability to:

adhere to relevant OH&S requirements

plan tests or analyses

carry out tests and measurements

perform quantitative and qualitative analysis

trial, document and evaluate new procedures

record and validate results

Consistency in performance

Competency should be demonstrated in a range of actual or simulated explosive analysis contexts over time

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or under conditions which accurately simulate a realistic workplace.

Evidence should be gathered through observation of a range of basic tests supported by targeted questioning to assess underpinning knowledge.

Evidence could also include examples of records and workplace documentation, and analysis of results.

Specific resources for assessment

Access is required to:

facilities and resources used in the research, development and proof of explosive ordnance; it may require access to a licensed explosive site and appropriate firing/test range

Method of assessment

This unit may be assessed with the following unit:

DEFEO101D Work safely with explosive ordnance

In a public safety environment assessment is usually conducted via direct observation in a training environment or in the workplace via subject matter supervision and/or mentoring, which is typically recorded in a competency workbook.

Assessment is completed using appropriately qualified assessors who select the most appropriate method of assessment.

Assessment may occur in an operational environment or in an industry-approved simulated work environment. Forms of assessment that are typically used include:

direct observation

interviewing the candidate

journals and workplace documentation

third party reports from supervisors

written or oral questions


Submission Requirements

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

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.

This describes the essential skills and knowledge and their level, required for this unit.

Required Skills

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

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
