Concept for testing accessibility

Objective:

Ensure that your website meets the requirements of the Accessibility Improvement Act (BFSG) and the international accessibility guidelines (WCAG 2.1).

Steps to check accessibility:

1. preparation

  • Assessment:

    • Create
    a
      list
    • of all pages and functions of the website (e.g. homepage, contact form, content such as PDF documents, search functions).
    • Analyse the technologies and page types
    • used
    • .
  • Define

    test criteria:

      Use
    • the WCAG 2.1 guidelines with a focus on conformance levels A and AA.
    • Check
    • for compatibility with national requirements (BITV 2.0).
  • Select

    testing tools

    :

      Automated
    • tools: e.g. WAVE, Axe, Lighthouse.
    • Manual
    • tests: Screen reader (e.g. NVDA or JAWS), keyboard navigation.

2. automated testing

  • Execution:
    • Apply
    • automated
    • tools to the website to identify initial issues such as missing alternative text, poor contrast, incorrect ARIA roles.
  • Analyse
  • report
  • :
    • Create
    • list
    • of automated issues found.
    • Categorise
    • errors
    • (critical, moderate, minor).

3. manual check

  • Visual

    check:

      Check
    • design for sufficient contrast (at least 4.5:1 for text and background).
    • Check
    • legibility of fonts and sizes.
  • Screen

    reader

    test

    :

    • Check the
    • navigation
    • of the website with a screen reader.
    • Ensure
    • that content is read out logically and comprehensibly.
  • Keyboard

    test

    :

      Check
    • whether all interactive elements (e.g.
  • forms, buttons, buttons,
    • text, etc.) can be
    • read
    • .
    Check
    • whether
    • all
  • interactive
    • elements (
    • e.g. forms, buttons, menus) can be fully operated using the keyboard.
  • Content

    check

    :

      Check
    • whether alternative texts for images are available and make sense.
    • Ensure
    • that multimedia content (e.g.
  • videos
    • ) contains
  • subtitles or
    • transcripts.
  • Create
  • report
  • :
    • Create
    • list
    • of issues found.
    • Categorise
    • errors
    • (critical, moderate, minor).

4. check the documents

  • Review
  • the PDF documentsprovided on the website :
      Ensure
    • that the PDFs are accessible.
  • Create
  • report
  • :
    • Create
    • list
    • of issues found.
    • Categorise
    • errors
    • (critical, moderate, minor).

5. user feedback

  • Set up
  • an accessibility reporting centre
  • :
      Contact form
    • or email address on the website so that users can report barriers.
  • Involve a
  • test group
  • :
    • Have
    • people
    • with different disabilities test the website.
    • Get
    • feedback
    • on usability.
  • Create
  • report
  • :
    • Create
    • list
    • of issues found.
    • Categorise
    • errors
    • (critical, moderate, minor).

6. document the results

  • Summarise
  • reports
  • :
      Identified
    • barriers and their impact.
    • Suggest
    • remediation with prioritisation by urgency.
  • Document
  • test log
  • :
    • Document
    • all
    • tests and tools performed.

Implementation of the findings:

    Develop
  • solutions:
      Collaborate
    • with developers and designers to remove barriers.
    • Ensure
    • code is semantically correct and ARIA roles are used appropriately.
  • Review:
    • Rerun all tests
    • after
    • issues are resolved.

Ensure accessibility in the long term:

  • Regular

    checks:

      Quarterly
    • check the website for accessibility.
  • Training:

      Train
    • editors on how to handle accessible content.

  • Monitoring

    and feedback:

      Establish
    • a monitoring system to continuously check changes and new content for accessibility.
