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


Course Description

 This unit of competency covers the ability to prepare working solutions and to check that existing stocks are suitable for use. Calculations of quantities, choice of reagent grades and required dilutions will be specified by the supervisor.

Overview of Assessment


The assessment tasks for this course may include assignments, practical reports and written tests.




Assessment Tasks

Assessment 1
Laboratory Practice:
a) poster done out of class & handed in and
b) role plays assessed in class.

The assignment is worth 20% of the overall course grade.

Assessment 2
Titration Practical :
Your practical skills in this experiment will be evaluated as Satisfactory (S) or Not Yet Satisfactory (NYS)
Your report will be graded and worth 30% of the overall course grade.


Assessment 3
Demonstration of Laboratory Skills
Your practical skills in this experiment will be evaluated as Satisfactory (S) or Not Yet Satisfactory (NYS)

Assessment 4
Week 17
This is a closed book examination covering all material in the course. You will be provided with a Periodic Table and a Formulae Sheet.
The examination is worth 50% of the overall course grade.


Assessment Matrix

Other Information

This course is graded in accordance with competency-based assessment, but which also utilises graded assessment
CHD Competent with High Distinction (80 – 100%)
CDI   Competent with Distinction (60 – 79%)
CC   Competent with Credit (50 – 59%)
CAG Competency Achieved – Graded (0 – 49%)
NYC  Not Yet Competent
DNS  Did Not Submit for assessment

All assessment types must be passed (exams, prac, and assignments etc.). For example, if there are two tests you need to have an average of 50% to pass. You can’t make up marks from one type of assessment to another (e.g. pass the tests but fail the prac component).
Late work that is submitted without an application for an extension will not be corrected.
APPLICATION FOR EXTENSION OF TIME FOR SUBMISSION OF ASSESSABLE WORK- A student may apply for an extension of up to 7 days from the original due date. They must lodge the application form (available online at least 24 hours before the due date. The application is lodged with the School Admin Office on Level 6, Bdg 51, or emailed to the Coordinator (
Students requiring extensions longer than 7 days must apply for Special Consideration (see the ‘Help me’ link in blackboard, via myRMIT studies or For missed assessments such as exams - you (& your doctor if you are sick) must fill out a special consideration form. This form must be lodged online with supporting evidence (e.g. medical certificate), prior to, or within, 48 hours of the scheduled time of examination.
If you miss an assessment task due to unavoidable circumstances, you need to follow the procedure of special consideration and apply within the allowed time frame.
