Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.
Pre-requisites and Co-requisites
Students must demonstrate the underpinning knowledge and practical skills of Prepare, standardise & use solutions (ONPS 5200C) by gaining a satisfactory pass in first semester. If these requirements are not met, additional classes may be provided to students.
Course Description
This unit of competency covers the ability to interpret chemical test requirements, prepare samples, conduct pre-use and calibration checks on equipment and perform routine chemical tests/procedures. These tests will involve several measurement steps. The unit includes data processing and interpretation of results and tracking of obvious test malfunctions where the procedure is standardised. However, personnel are not required to analyse data, optimise tests/procedures for specific samples or troubleshoot equipment problems where the solution is not apparent.

Theory Online Quizzes
Students are expected to do the set readings each week. Powerpoint slides are also available for your review. The powerpoints summarise the readings. Each week the quiz tests you on key concepts from the readings. In theory classes there will be discussion based around the questions, and any questions or difficulties you are having with the topic. Each quiz will be available for a limited time only. If you are ill for the whole time the quiz is available, you will need to provide a medical certificate or else you will not get any marks for that week’s quiz. IT IS VERY IMPORTANT THAT YOU SUBMIT THE QUIZ PROPERLY. If you do not submit it properly, so that a score is achieved, you will not get the marks for that quiz. It is your responsibility to ensure your quiz is submitted properly. Please check with the teacher if you are unsure if you are submitting the quiz correctly.
Logbook
Results from each practical need to be recorded in your logbook. This is an important aspect of developing your record-keeping skills. Logbooks are to be submitted at the end of semester.
Practical Reports
Practical reports are indicated in the Practical Manual. These pracs must have a formal report submitted as part of your assessment. Each practical report is due two weeks after the prac has been done. Late reports will incur loss of marks for each day late, up to one week after the due date. Prac reports will not be accepted after this time.
If you are absent for a practical that is to be written up, a medical certificate must be provided and special consideration applied for. In this case another practical exercise needs to be written up – as negotiated with the teacher. If you are absent when the prac is to be written up but do not / cannot apply for special consideration, another prac may not be written up. No marks will be allocated in this case.
Class attendance
Students must attend at least 80% of classes to pass the course.
A medical certificate must be provided and special consideration applied for if you are absent.
