Student Guide for Written Knowledge Assessment
Overview of Assessment	This is a written assessment task you will be assess on your knowledge of selecting and using bearings, seals, gaskets, sealants and adhesives. The topics that will be covered in the assessment are: 1. Prepare to select and use bearings, seals, gaskets, sealants and adhesives 2. Install bearings, seals and gaskets 3. 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 56 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 select and use bearings, seals, gaskets, sealants and adhesives:Manufacturer specifications, procedures and supporting information for preparing, inspecting and installing sealants and adhesivesManufacturer specifications, procedures and supporting information for preparing, inspecting and installing bearings, seals and gasketsWorkplace procedures required to select and use bearings, seals, gaskets, sealants and adhesives, including:Establishing the serviceability of tools and equipment Documentation 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 selecting and using bearings, seals, gaskets, sealants and adhesives, including:Procedures for working safely with sealants and adhesives, lubricants and greasesEnvironmental requirements relating to selecting and using bearings, seals, gaskets, sealants and adhesives, including:Procedures for trapping, storing and disposing of excess materials produced when applying sealants and adhesivesProcedures for trapping, storing and disposing of lubricants and greases released during work processesIdentification and function of: Bearings, including:BallRollerPlainSeals, including:LipFaceO-RingSquare section ringMetal surfaceGaskets, including:Treated paperCorkComposite materialsMetal, synthetic, rubber, fibre, and nylonTypes, characteristics, uses and limitations of sealants and adhesives, including application techniquesInspection, service, installation and adjustment procedures, including:Bearings, including:Roller typesBall typesPlain typesSeals and sealing surface conditionGasketsTypes and applications of bearing lubricants and greases
Assessment conditions	Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting. Assessment MUST include direct observation of tasks. Where assessment of competency includes third-party evidence, individuals MUST provide evidence that links them to the bearings, seals, gaskets, sealants and adhesives they have selected and used, e.g., Repair orders. Assessors MUST verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application. The following resources MUST be made available: Automotive repair workplace or simulated workplaceWorkplace instructionsManufacturer specifications relating to bearings, seals, gaskets, sealants and adhesivesVehicle or equipment requiring the application of bearings, seals, gaskets, sealants and adhesivesBearings, seals, gaskets, sealants and adhesives as specified in the performance evidenceTools, equipment and material appropriate for installing bearings, seals and gaskets. Assessors of this unit MUST satisfy the requirements for assessors 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 2, 5, 7, 8, 11, 13 & 45Websites –Trainer 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.
