    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating consistent and correct selection and use of at least six items of PPE as specified in the task brief, with justification for each choice.
    • Expect evidence of accurately interpreting and following all relevant drawings and specifications, including layouts, cross sections, and OLE system design range documentation, with no unauthorised deviations.
    • Learner must prove systematic checking of tools, plant, and equipment for safety and suitability before use, and adherence to PUWER and LOLER requirements, including lifting plans.
    • Assessor should observe the correct application of installation methods—such as shimming, mechanical fixing, torque loading, and locking device application—ensuring all fasteners are tightened to specified torque values and marked.
    • Credit only given if the completed installation passes all checks: correct position, clearances, level, rake, alignment, visual completeness, and freedom from damage, as verified against the specification.
    • Evidence must include a properly completed installation record or handover document, signed and dated, with any non-conformances or issues reported in line with procedures.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡For practical assessments, adopt a systematic approach by creating and following a step-by-step checklist that mirrors the safe system of work; verbalise your actions to demonstrate your thought process to the assessor.
    • 💡Always cross-reference the installation specification with the actual structure and drawings before any physical work, and if a discrepancy is found, report it immediately rather than making assumptions.
    • 💡During knowledge questioning, refer explicitly to key legislation and Network Rail standards (e.g., Rule Book module AC, HSWA 1974, LOLER 1998, PUWER 1998, Electricity at Work Regulations 1989) to demonstrate depth of understanding.
    • 💡When using torque wrenches, state the required torque value aloud, show the assessor the setting, and after tightening, visibly mark the fastener with a torque seal or paint pen to confirm compliance.
    • 💡Treat the work area as if it were live at all times; maintain the correct safe distance from OLE and use insulated tools where required, even in a simulated exercise, to embed essential safety habits.
    • 💡When answering questions about fault diagnosis, always describe your step-by-step reasoning. Examiners award marks for method, not just the final answer.
    • 💡Use technical terminology correctly. For example, distinguish between 'maintenance' (preventative) and 'repair' (corrective) to show depth of understanding.
    • 💡In practical assessments, prioritise safety. Always mention PPE, isolation procedures, and risk assessments before starting any task.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to check the currency and validity of installation documentation (drawings, instructions) before commencing work, leading to potential use of obsolete specifications.
    • Neglecting to obtain formal authority or a permit to work before starting installation activities, especially in an electrified zone, which constitutes a serious safety breach.
    • Over- or under-tightening bolts and not using a calibrated torque wrench, resulting in insecure connections or component damage, and failing to mark fasteners as evidence of correct torque.
    • Misinterpreting cross-sectional drawings or OLE design range data, causing incorrect positioning of steelwork, which can lead to dangerous clearances and operational failures.
    • Working at height without properly wearing and securing a safety harness, or attaching it to an unsuitable anchor point, a frequent cause of near misses and accidents.
    • Omitting final checks for completeness or damage, then signing off installation records without confirming that all locking devices are engaged and all components are secure.
    • Misconception: The diploma only requires practical skills, not theoretical knowledge. Correction: You must demonstrate understanding of engineering principles and safety regulations, which are assessed through written exams and assignments.
    • Misconception: Fault diagnosis is just trial and error. Correction: Effective diagnosis requires a logical, systematic approach using tools like flowcharts and test equipment to minimise downtime and ensure accuracy.
    • Misconception: Health and safety is just common sense. Correction: Rail environments have specific hazards (e.g., high voltage, moving trains) that require formal risk assessment and adherence to strict procedures.
