    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating a clear design process that includes user needs analysis, wireframe sketches, and a specification of core features.
    • Expect evidence of app functionality through screenshots, video demonstration, or working prototypes that show navigation and interaction as intended.
    • Assessors should look for a documented trial phase that captures identified bugs, compatibility issues, or usability concerns, along with a reflective review explaining how improvements were implemented.
    • Design a mobile app with clear purpose and target audience.
    • Create a working prototype using appropriate tools.
    • Trial the app and document test results.
    • Review and suggest improvements based on feedback.
    • Design a mobile app with clear purpose and user interface.
    • Create a functional app using appropriate development tools.
    • Trial the app to identify bugs and usability issues.
    • Review and improve the app based on feedback and testing.
    • Produces a clear design document including wireframes and user flow.
    • Creates a functional mobile app prototype using appropriate tools.
    • Trials the app with users and collects feedback.
    • Reviews and improves the app based on trial feedback.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Ensure your portfolio demonstrates a clear narrative from design to final review; label all documents and link evidence to each learning outcome.
    • 💡When trialling your app, systematically record test cases, expected outcomes, and actual results—this forms strong evidence for assessment criteria.
    • 💡In your review, be specific about what you changed and why; use before-and-after comparisons to showcase your improvement process effectively.
    • 💡Use wireframes to plan your app layout before coding.
    • 💡Keep a log of tests and changes made.
    • 💡Justify your design choices with reference to user needs.
    • 💡Start with a simple app idea and build complexity gradually.
    • 💡Use wireframes to plan the user interface.
    • 💡Document bugs and how you fixed them for evidence.
    • 💡Use industry-standard tools like Figma or Adobe XD for design.
    • 💡Document your testing process and user feedback clearly.
    • 💡Focus on usability and user experience in your review.
    • 💡Use real-world examples in your answers to show application of knowledge, such as describing how a business uses email marketing tools.
    • 💡Always define technical terms clearly when first used, as this demonstrates understanding and helps structure your response.
    • 💡In practical tasks, follow instructions precisely and double-check your work for errors, as attention to detail is highly valued.

    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to design for multiple screen sizes and orientations, resulting in an app that only works on one device type.
    • Focusing solely on visual design without mapping out the logical flow and navigation, leading to a confusing user experience.
    • Skipping thorough testing on actual devices, relying only on emulators, which can miss real-world performance issues.
    • Treating user feedback as an afterthought rather than integrating it iteratively during development.
    • Skipping the design phase and coding directly.
    • Not testing on multiple devices or scenarios.
    • Failing to document the review and improvement process.
    • Skipping the design phase and coding without a plan.
    • Not testing on different devices or screen sizes.
    • Ignoring user feedback during the review stage.
    • Skipping the design phase and coding without a plan.
    • Not testing on multiple devices or screen sizes.
    • Failing to address user feedback in the improvement cycle.
    • Misconception: 'Digital industries only involve coding.' Correction: While programming is important, roles also include IT support, digital marketing, project management, and user experience design.
    • Misconception: 'Cybersecurity is only about antivirus software.' Correction: It also involves policies, user training, and secure configuration of systems.
    • Misconception: 'Networking is just about connecting computers.' Correction: It includes understanding protocols, data transmission, and network security measures.
