Description | |||
Employability Skills | |||
Learning Outcomes and Application | This unit of competency describes the skills and knowledge to perform straightforward histological procedures involving processing and sectioning (by hand or rotary microtome) of plant and/or animal tissues in paraffin wax. This unit of competency applies to laboratory assistants working in biomedical, biotechnology, environmental and education sectors. Personnel will work under direct supervision and have ready access to workplace procedures. No licensing or certification requirements exist at the time of publication. However, regulations and/or external accreditation requirements for laboratory operations exist, so local requirements should be checked. Relevant legislation, industry standards and codes of practice within Australia must also be applied. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. |
