    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating a systematic approach to diagnosing hardware or software faults, including documentation of steps taken.
    • Award credit for evidence of creating and implementing a maintenance schedule that includes both routine (e.g., disk clean-up, updates) and non-routine tasks (e.g., hardware replacement).
    • Award credit for showing effective file management techniques, such as organizing directories, archiving, and using compression to free up storage and improve access times.
    • Award credit for reviewing system performance metrics (e.g., CPU usage, response times) and proposing hardware or software modifications based on analysis.
    • Provide evidence of a documented routine maintenance schedule for hardware and software, including frequency, responsible personnel, and procedures.
    • Demonstrate effective file management practices, such as regular disk cleanup, defragmentation (if applicable), and logical folder structures, to enhance system responsiveness.
    • Showcase a troubleshooting log detailing incident identification, diagnostic steps, resolution actions, and verification of system stability for at least two different IT problems.
    • Present a review report evaluating current system performance and proposing justified hardware or software modifications to address identified bottlenecks.
    • Award credit for demonstrating the ability to conduct disk cleanup, defragmentation, and other standard optimisation tasks to improve hardware and software efficiency.
    • Award credit for implementing a structured file management system, including regular archiving, deletion of redundant files, and effective folder hierarchies to boost performance.
    • Award credit for accurately diagnosing common IT system faults using systematic troubleshooting methodologies and relevant diagnostic tools, then applying effective solutions promptly.
    • Award credit for creating a comprehensive maintenance schedule that details routine tasks (e.g., updates, patches) and includes clear procedures for non-routine maintenance and unexpected failures.
    • Award credit for reviewing system performance post-modification, using comparative data to evaluate success and recommending further hardware or software adjustments as needed.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡When documenting troubleshooting processes, always record initial symptoms, actions taken, and outcomes to demonstrate a methodical approach for assessment.
    • 💡For portfolio evidence, include before-and-after performance metrics (e.g., boot time, storage usage) to quantify improvements.
    • 💡Relate maintenance plans to potential real-world business impacts, such as minimizing downtime costs, to show higher-order thinking.
    • 💡For the maintenance plan, ensure it covers both hardware (e.g., dust removal, cable checks) and software (e.g., patch management, antivirus updates) and aligns with organisational policies.
    • 💡When troubleshooting, document every step including failed attempts; assessors value the process as much as the final solution.
    • 💡Use performance monitoring tools (e.g., Task Manager, Resource Monitor) to provide quantitative evidence of improvements before and after interventions.
    • 💡Always reference specific performance metrics (e.g., boot time, CPU usage) when proposing or evaluating optimisations in your assignments.
    • 💡Document every troubleshooting step in a clear log, justifying your actions to demonstrate methodical problem-solving and earn higher marks.
    • 💡Justify all maintenance decisions with reference to industry best practices or recognised frameworks (e.g., ITIL) to show professional understanding.
    • 💡Use before-and-after performance data to provide concrete evidence of the impact of your optimisation efforts.
    • 💡Ensure your maintenance plan considers interdependencies between hardware and software, showing holistic system management.
    • 💡Always read the task brief carefully and note the specific software features required. For example, if a task asks for a 'chart', ensure you choose the correct chart type (e.g., bar, line, pie) and include titles and labels.
    • 💡Save your work frequently and in the correct file format (e.g., .docx, .xlsx). Examiners may deduct marks for incorrect file naming or format, so follow instructions precisely.
    • 💡Use keyboard shortcuts to speed up your work (e.g., Ctrl+C for copy, Ctrl+V for paste). This demonstrates efficiency and leaves more time for checking your answers.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to back up data before performing system modifications, leading to potential data loss.
    • Assuming that a single troubleshooting step resolves an issue without verifying system stability, resulting in recurring problems.
    • Confusing routine maintenance with troubleshooting; routine maintenance is preventive, while troubleshooting is reactive.
    • Confusing routine maintenance (e.g., updates, cleaning) with troubleshooting reactive fixes.
    • Neglecting to test system performance after applying a fix, assuming the problem is resolved without verification.
    • Overlooking the impact of file fragmentation or cluttered storage on overall system speed, focusing only on hardware upgrades.
    • Neglecting regular software updates and patch management, leading to security vulnerabilities and performance degradation.
    • Failing to test system performance after making changes, resulting in overlooked inefficiencies or new issues.
    • Mistaking symptoms for root causes during troubleshooting, which leads to repeated call-outs and unresolved problems.
    • Overlooking the importance of documentation; not recording maintenance actions makes future diagnostics and accountability difficult.
    • Assuming that a one-size-fits-all solution applies to all IT systems without considering specific hardware configurations or user requirements.
    • Misconception: 'Spreadsheets are just for simple calculations.' Correction: Spreadsheets can handle complex data analysis using functions like VLOOKUP, pivot tables, and conditional formatting, which are essential for business intelligence.
    • Misconception: 'Mail merge is only for letters.' Correction: Mail merge can be used for emails, labels, envelopes, and directories, saving time when personalising bulk communications.
    • Misconception: 'Database queries are too difficult.' Correction: With practice, creating queries using criteria and calculated fields becomes straightforward and is a powerful way to extract specific data.
