Report:
Sub-study content digital accessibility website Werken bij de gemeente Capelle aan den IJssel

Summary of the evaluation findings

The website Contentaudit Werken bij de gemeente Capelle aan den IJssel English version does not comply to WCAG 2.1 level AA yet. 7 out of 50 success criteria contain one or more issues. This document describes to what extent the website meets the accessibility requirements captured in WCAG, the Web Content Accessibility Guidelines.

The website werkenbijcapelleaandenijssel.nl was investigated on May 4, 2023. The investigation was carried out using the evaluation method WCAG-EM. The content does not yet meet all the success criteria examined. This report forms the basis for further work on accessibility. Only the content was checked for this sub-study. This report and the system investigation/platform investigation report 'Rapportage Toegankelijkheidsaudit WCAG 2.1 AA www.werken-bij-audit.jobsrepublic.eu/JobsRepublic' jointly determine the extent to which the website complies. The 2 reports can also be used together in the accessibility statement.

The content of the website is almost entirely accessible. There are a few more points to note:

• Meaningful icons about 'vacatures' do not have accessible text
• Video can be paused or made fullscreen with one key, this can cause problems with speech software.
• Edges of input fields have too low a contrast, this may be a technical problem.

The audit focuses specifically on the accessibility of the website for people with a disability, such as people who are blind, deaf, low-literate or have other functional problems. For them it is important that the website is technically and substantively designed in such a way that the site is usable. Optimizing a website for accessibility has more advantages; it makes the website more usable for everyone (for example also for people who look at their mobile phone in a sunny environment) and it makes the site easier to find in search engines.

Scope of the evaluation

Overview of audit results

Reading Guide

This evaluation is a snapshot. The website might have been changed. The problems found are only examples. Therefore, check for any problem whether this also occurs in other places. This evaluation is just a sample of a few pages. As many different types of pages are included in the sample as possible to get the best impression of the accessibility. Pay attention! New problems may arise when making improvements or changes to the website/app. Success criteria marked with "Not present" are automatically approved. Success criteria marked with "Unknown" or "Can't tell" are not approved.

Basis for this evaluation

The audit was conducted based on the evaluation method of the W3C, WCAG-EM. This is largely done manually by taking a sample. For a quickscan we use parts of this methodology. Despite all the researcher's care and experience, it is possible that a problem has not been identified. Keep in mind that in a next audit certain parts could be assessed differently because of further development of techniques and assistive software. Tools are used in the manual audit.
