Student Guide for Written Knowledge Assessment
Overview of Assessment	This is a written assessment task you will be assess on your knowledge of balancing wheels and tyres. The topics that will be covered in the assessment are: Prepare to balance wheels and tyres Conduct wheels and tyres pre-balance inspection Carry out balancing procedures Complete work processes This assessment will ensure that the elements, performance criteria, performance evidence and knowledge evidence required, and conditions are adhered to demonstrate competency in this unit assessment task. Read the assessment carefully before commencing.Your Assessor will use the assessment criteria in this document and will provide feedback / comment. 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 34 questions comprising of Multiple Choice, True and False, Fill-in the Gap and Short Answer questions.
Time allowed	On average, the Assessment should take 2 – 4 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: – Key policies and procedures for balancing wheels and tyres, including:How to locate and interpret manufacturers specifications or equivalent information and workplace procedures for balancing wheels and tyres The following workplace health and safety requirements and procedures relating to balancing wheels and tyres:Lifting and supporting vehicles and wheelsWorking with balancing machines, including rotating components and flying objectsEnvironmental requirements relating to balancing wheels and tyresProcedures for pre-balance inspection of wheels and tyresWorkplace housekeeping and documentation proceduresWheel balancing machinery, including:Off vehicle balancersOn vehicle balancersWheel balancing equipment and concepts, including:Tyre and wheel run-outStatic and dynamic balanceThe following out of balance effects on wheels:Wheel hop or trampWheel shimmyVibrationTread wear Types and applications of wheel weights.
Assessment conditions	The assessment MUST: Include access to:An automotive repair workplace or simulated workplace that reflects workplace conditions – where simulation is used, it MUST reflect real working conditions by modelling industry operating conditions and contingencies, as well as, using suitable facilities, equipment and resources Repair orders and workplace instructions relating to balancing wheels and tyres activityWorkplace procedures relating to balancing wheels and tyres activityManufacturer wheel balancing specifications or equivalent documentation Four [4] different wheels and tyres for balancingWheel balancing machinery Two [2] different vehicles or machinery requiring wheel/tyre balancingTools, equipment and materials appropriate for balancing wheels and tyresBe demonstrated in the workplace or in a simulated environment that reflects workplace conditionsBe conducted in a safe environmentBe assessed in compliance with relevant policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessedConfirm consistent performance can be applied in a range of relevant workplace circumstances.
Assessor Requirements	Assessors of this unit MUST: Satisfy the assessor requirements in applicable vocational education and training legislation, frameworks and/or standards
Resources required	Learning Resources available to students include: Automotive Technology (A System Approach) 7th Edition – Chapters 5, 6, 7, & 45Websites –https://en.wikipedia.org/wiki/Tire_balanceTrainer Handouts
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.
