Perform environmental microbiological tests

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria


Receive microbiological samples


Check samples and accompanying documentation in accordance with enterprise procedures


Log samples and record sufficient details to enable accurate tracking and chain of custody


Distribute samples for local testing or dispatch samples to other testing facilities, as necessary


Store samples appropriately where testing or transport is to be delayed


Prepare for safe microbiological work and aseptic applications


Select work area and equipment required for the safe handling of materials that may contain microorganisms of specified risk groups


Wear protective clothing, replacing it when contamination is suspected


Apply correct disinfection procedures to work areas before and after use


Locate relevant emergency equipment for timely response to microbiological accidents


Apply standard precautions when handling biological materials


Minimise the production and release of aerosols, using biological safety cabinets, where necessary


Clean up spills, and report all spills and suspected incidents to supervisor


Wash hands before and after laboratory work and when contamination is suspected


Ensure the safe collection and disposal of biohazardous materials and other laboratory wastes in accordance with enterprise procedures


Process samples for direct examination


Prepare thin smears of samples for subsequent staining to enable microscopic identification of cells


Prepare liquid films of specimens for direct observation of cell structure


Prepare samples to concentrate material for subsequent staining or microscopy


Prepare pure cultures for microbiological work and aseptic applications


Select culture media to maximise growth of microorganisms and cells


Inoculate media aseptically, applying techniques suitable for purpose of culture


Incubate inoculated media in conditions to optimise growth of organisms and cells


Subculture on suitable media to optimise production of pure cultures


Perform environmental microbiological analyses


Identify major microorganisms and groups of microorganisms in air, water and soil samples


Count cells in undiluted samples to indicate the dilution necessary to reliably count organisms in culture


Prepare serial dilutions of samples aseptically for culture and colony counting


Count colonies for calculating number of viable organisms per unit volume


Count microorganisms in samples and cultures using spectrometric and electronic methodologies, where relevant


Estimate and document uncertainty of measurement in accordance with enterprise procedures, where relevant


Use rapid detection techniques to monitor the presence of microorganisms in water


Use indicator organisms to estimate the likely presence of other pathogenic species


Examine test data for legislative compliance


Confirm data are the result of valid measurements


Report details of sampling/testing procedures and quality assurance in accordance with legislative requirements


Report data in the required format with the appropriate accuracy, precision, statistic type and units


Compare data with specified assessment criteria


Comment on any significant data trends and identify the possible causes or implications


Identify atypical or out-of-range results and the risk and/or instances of potential/actual non-compliance


Confirm all unexpected findings with supervisor


Maintain records


Enter approved data and results into enterprise information management system


Maintain instrument logs as required by accreditation checklists


Maintain security and confidentiality of all client information, data, test results and records
