Overview of Assessment


To achieve successful completion of this course students must demonstrate an understanding of all elements of Competency.
Assessment methods have been designed to measure achievement of each competency in a flexible manner over a range of assessment tasks. Technical requirements documentation, homework and in class exercises, written tests, practical problem solving exercises and practical tests. Students are advised that they are likely to be asked to personally demonstrate their assessment work to their teacher to ensure that the relevant competency standards are being met.

Assessment will incorporate a variety of methods including:

Group task
Completion of learning activities
Process Documentation worksheets
OHS Questionnaire
Studio Practice Checklists
Trouble shooting quiz  and observatioanal checklist


Assessment Tasks


1. Technical file –
The technical file will include printed samples from practical set tasks and process documentation worksheets. The worksheets relate directly to the task and are designed to help participants become familiar with processes, technical language, problem solving and analysing work practices.

The set tasks included in the technical file are:
• Prepare, cut and test a paper stencil
• Select screen and squeegee for colour testing
• Testing 3 colour film cut stencil
• Prepare photographic stencils and screens
• Testing 2 colour registered photographic placement print on a non woven substrate

2. Studio practice checklist –
Students will be required to submit 5 studio practice checklists throughout this unit. The checklists will enable participants to demonstrate knowledge of standard operating procedures and ability to conduct quality workplace practices. They also relate to general housekeeping in the print studio and individual contribution to maintenance and improvement.
The lists will typically be submitted after a practical activity and will require participants to check items off; eg, Has my screen been stored correctly? Have I cleaned and returned squeegee to the storage area?

3. Group task – analysis and brief presentation.
In small groups students will be asked to analyse design specifications to interpret stencil requirements.

4. Assessment through observation –
Participants will be required to demonstrate a range of practical tasks during class sessions

5. Quiz
There will be 4 quizzes undertaken in this unit:
1. Work processes related to preparing stencils and screens
2. Trouble shooting - Testing stencils and screens
3. Trouble shooting – Screen Preparation
4. OHS- This quiz is designed to ensure students are aware of all aspects related to OHS in the print room and carry out work according to current OHS practices

Please note quizzes will be available for students to examine the week prior or will be undertaken over multiple sessions, there will be no surprises as far as expected required knowledge. They are designed to reinforce understanding and equip students with the tools to analyse and solve problems associated with preparing stencils and screens.

Other Information

Prepare stencils and screens is the first screen print unit undertaken in the Diploma of Textile Design and Development. This unit is studio based, incorporating some theory and many practical exercises. The exercises will enable participants to gain a sound understanding of basic processes and techniques associated with preparing and testing stencils and screens.

The course will be offered in intensive mode over a  9 week period  during the semester. This intensive mode of learning allows for longer periods of studio access which is simulates industry workplace . Please read the timeatble as sessions rather  than weeks - one session in the morning the other in the afternoon.

Due to the session  sceduling  and access to facilities it is strongly recommended that students attend every session .
