Examination specifi cations

Overall conditionsThe examination will be sat at a time and date to be set annually by the Victorian Curriculum and Assessment Authority (VCAA). VCAA examination rules will apply. Details of these rules are published annually in the VCE and VCAL Administrative Handbook.There will be 15 minutes reading time and 1 hour and 30 minutes writing time.The examination will be marked by a panel appointed by the VCAA.The examination will contribute 34 per cent to the study score.

ContentThe VCE VET Engineering Studies examination will be based on the fi ve compulsory units of competency from Units 3 and 4.MEM12024A Perform computations Release 1 30 hoursMSAENV272B Participate in environmentally sustainable work practices Release 1 30 hoursVU20910 Produce basic engineering sketches and drawings 20 hoursVU20911 Handle engineering materials 20 hoursMSS402040A Apply 5S procedures in a manufacturing environment Release 1 40 hours

The examination will focus on the essential knowledge and an understanding of the essential skills as outlined in the elements and performance criteria of the relevant units of competency. Individual questions may assess more than one unit of competency. The electives will not be examined.

FormatThe examination will be in the form of a question and answer book.The examination will consist of two sections. Section A will consist of 20 multiple-choice questions worth 1 mark each and will be worth a total of 20 marks.Section B will consist of short-answer and multiple-part questions, including calculations and sketches. Short scenarios and stimulus material may be provided. This section will be worth 80 marks.All units of competency will be examined in both sections of the examination.All questions will be compulsory. The total marks for the examination will be 100.Answers to Section A are to be recorded on the answer sheet provided for multiple-choice questions.

Relevant referencesThe following publications should be referred to in relation to the VCE VET Engineering Studies examination:• VCE VET Engineering Studies Program Booklet (published November 2012)• VCE VET Engineering Studies Assessment Guide (published February 2010)• VCE VET Engineering Studies page on the VCAA website

AdviceThe following sample examination demonstrates changes to the examination format and to the types of questions that may be asked on the examination. Teachers and students should pay particular attention to questions that relate to the units of competency MEM12024A Perform computations, MSAENV272B Participate in environmentally sustainable work practices and MSS402040A Apply 5S procedures in a manufacturing environment. Past examination papers are a useful reference for examples of questions related to VU20910 Produce basic engineering sketches and drawings and VU20911 Handle engineering materials.As examination questions may be based on more than one unit of competency, questions will not be presented under unit headings.Answers to multiple-choice questions are provided on page 20.Answers to other questions are not provided.
