Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:
safely performing microscopic examination of at least three (3) different samples and correctly identifying and reporting the characteristics of each
checking suitability of samples, such as labelling, spillage, spoilage due to incorrect storage and transport conditions, temperature control and suitability for the examination
safely preparing routine biological and/or physical samples in accordance with workplace procedures or standard methods
checking the quality of prepared samples, such as:
clean and scratch-free microscope slides to reduce artefacts
preparation according to specified procedure/method
homogeneous suspension of sample
films and smears that have been fixed rapidly
thin films with a monolayer of cells
appropriate whole mounts for intact organisms
correct sample identification during and after processing
performing pre-use checks of equipment, such as calibration, routine cleaning and maintenance, and use by dates of reagents
setting up a light microscope for optimal resolution
accurately observing, identifying and reporting sample characteristics
performing counts on samples and basic measurements using grids
performing accurate calculations as required by the method, such as:
dilutions
percentage viability
number of cells in original sample after dilution
calculation of cells/ml in a number of squares of a counting chamber
interpreting and recording test results reliably
logging and tracking samples through all steps from sample receipt to completion of the examination and reporting
minimising cross-contamination and contamination of the laboratory and environment
using personal protective equipment (PPE) and safety procedures to maintain personal safety and that of others
handling/storing samples and equipment and collecting/disposing of waste in accordance with workplace procedures.
Must provide evidence that demonstrates knowledge of:
nature of samples, sample preparation methods, methods of examination and associated hazards
parts and functions of a light microscope and steps taken to optimise the resolution of images
importance and appropriate use of controls and certified reference materials
workplace and/or legal traceability requirements
relevant work health and safety (WHS) and environment requirements.
Judgement 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).
This unit of competency may be assessed with:
MSL922001 Record and present data
MSL933002 Contribute to the achievement of quality objectives
MSL943002 Participate in laboratory or field workplace safety
MSL953001 Receive and prepare samples for testing
Holistic assessment methods include:
review of data records prepared by the candidate, such as counts, observations and results
feedback from supervisors and peers about adherence to workplace procedures and sample preparation/examination methods
observation of the candidate performing microscopic examinations
oral/written questions about workplace procedures covering safe preparation and examination of samples.
Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to:
a standard laboratory equipped with appropriate equipment, including light microscopes and samples
workplace procedures, standard methods and materials
equipment, such as glass slides, counting chambers (e.g. haemocytometer), optical graticules and stage micrometers, and tissue culture flasks
a light microscope, such as:
bright field illumination microscope up to 1000 x magnification
stereomicroscopes and dissection microscopes
compound microscope
phase contrast microscope
inverted microscope.
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.
