You MUST answer all the questions in the assessment tasks in your own words and own handwriting.This is an “Open Book” assessment, and students can use the resources listed in the “Resources Required” section below.
Task/s to be assessed	To complete this written assessment, you will need to answer the 64 questions comprising of Multiple Choice, True and False, Fill-in the Gap and Short Answer questions.
Time allowed	On average, the Assessment should take 4 – 6 hours to complete.
Location	This theory assessment will be completed in a classroom under the supervision of a trainer/assessor.
Decision making rules	To receive a ‘satisfactory’ outcome for this assessment, students MUST successfully answer all questions. If a student achieves less than 100%, they can reattempt the assessment after further study has taken place. Students who cannot achieve a minimum of 100% you will not have satisfactorily completed this assessment Your assessor will be looking for the following in this assessment task: – Methods to locate and interpret information required to diagnose and repair light vehicle drive shafts, including:Information provided by customers and supervisors Manufacturer specifications and procedures or equivalent documentationWorkplace procedures required to diagnose and repair light vehicle drive shafts, including: Establishing serviceability of tools and equipmentDocumentation proceduresHousekeeping procedures, including:Examination of tools and equipmentStorage of equipmentIdentification, tagging and isolation of faulty equipmentDisposal of excess materialsRecycling proceduresWorkplace health and safety (WHS) requirements relating to diagnosing and repairing light vehicle drive shafts, including procedures for working with hazardous oilsEnvironmental requirements relating to diagnosing and repairing light vehicle drive shafts, including procedures for trapping, storing and disposing of oils released from drive shaftsOperating principles of light vehicle drive shafts and associated components, including:Torque reaction of rear axle housingsTorque steerPurpose and operation of light vehicle drive shafts and components, including:Propeller shafts, including:Single and multi-piece shaftsUniversal joints, including cross and yoke joints, double cardan joints and lobro jointsVelocity fluctuation of universal jointsShaft alignmentConstant velocity joints, including:Birfield jointsDouble offset jointsTripod jointsDiagnostic testing procedures for light vehicle drive shafts, including road testing procedures for:Drive shaft noise diagnosticVibrationRepair procedures for light vehicle drive shafts, including procedures for:Dismantling drive shaftsInspecting drive shaftsReassembling and aligning componentsPost-repair testing procedures for light vehicle drive shafts

Results/Re-assessment	The Assessor will grade the assessment and record the result on the front page of this document (S) – Satisfactory if all observable behaviours are correct and (NS) not satisfactory if any areas are left incorrectFeedback will be provided on either resultWhere a student receives a ‘NS – Not Satisfactory’ result, the assessor will discuss the area of the non-compliant observable behaviour and an opportunity given for re-assessment. This may be through direct observation or a different method of assessment e.g. verbal/oral questioning, problem solving exercise. If the outcome is again not satisfactory the student result will be deemed (NYC) not yet competent. Additional feedback will be given, and a time agreed upon for further assessment after additional training and skills practice has taken place, this information will be recorded, dated and signed in the re-assessment area on the last page of this documentWhere all the assessment tasks have been graded (S) Satisfactory, the student will be deemed C – Competent for the practical component and the result recorded and signed in the area indicated on the last page of this document
Reasonable Adjustment	If the participant is unable to undertake the written assessment as designed, an interview (verbal questioning) may be used as an alternate approach.
