Application
This unit of competency covers the ability to locate, record and collect evidence or samples that will be used for forensic examination or testing. Competency includes the ability to locate, collect, package, transport and store forensic samples.
This unit of competency is applicable to technical officers working in all industry sectors and government agencies, such as food, forensic, medical and environmental laboratories. The term forensic is used to describe the collection of samples that may have legal implications, such as those collected to verify insurance claims or prove paternity for payment of maintenance.
All operations must comply with relevant standards, appropriate procedures and/or workplace requirements. Although a supervisor may not always be present, the technical officer will follow standard operating procedures (SOPs) that clearly describe the scope of permitted practice, including varying workplace/test procedures and communicating results to people outside the laboratory.
While no specific licensing or certification requirements apply to this unit at the time of publication, laboratory operations are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked.

Evidence of Performance
Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:
safely locating, recording, collecting, packaging, transporting and storing forensic samples and evidence on at least three (3) different occasions
using close observation skills to locate samples and evidence
using chemical, optical and physical evidence and sample detection methods
accurately interpreting and applying evidence and sample collection methods
keeping accurate records
communicating any problems to a supervisor or industry professional using current and appropriate terminology
maintaining security, integrity and traceability of samples, evidence, sub-samples and documentation
completing chain of custody forms according to judicial and workplace requirements
storing and transporting samples according to judicial and workplace protocols
following workplace safety precautions and hazard control measures.
Evidence of Knowledge
Must provide evidence that demonstrates knowledge of:
terminology and principles of locating, recording, collecting, storing and transporting samples and evidence
legislative, regulatory, policy, procedural and quality system requirements for the location, collection, preservation, security, continuity and disposal of samples and evidence (exhibits)
potential limitations of own specialist knowledge and when to seek advice from other services
services available to assist in the documenting, collection, preservation and continuity of forensic evidence and samples
relevant hazards, and work health and safety (WHS) requirements.
Assessment Conditions
Judgment of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event.
This unit of competency is to be assessed in the workplace or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept in each case).
Holistic assessment methods include:
review of job sheets or journal of activities completed by the candidate
review of workplace documentation completed by the candidate
feedback from peers, supervisors and industry professionals about the candidate’s ability to reliably locate, record and collect forensic samples
observation of candidate collecting a range of samples and evidence
oral or written questioning of required knowledge, such as judicial protocols, traceability, sample identification and collection methods.
Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to:
workplace procedures and standard methods
sample containers
containers for transporting samples.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
The assessor must demonstrate both technical competence and currency.
Technical competence can be demonstrated through:
relevant VET or other qualification/Statement of Attainment AND/OR
relevant workplace experience
Currency can be demonstrated through:
performing the competency being assessed as part of current employment OR
having consulted with a laboratory about performing the competency being assessed within the last twelve months.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
