A form can work for most users and still exclude important groups
A revised government application form succeeds for typical desktop users but fails for people using assistive technology or unusual household arrangements. Equity testing examines whether legitimate users can complete the service fairly.
Identify relevant user groups
Consider disability, language, digital access and complex application circumstances as appropriate to the service.
Test complete journeys
Successful page loading is insufficient if submission, payment or confirmation fails.
Protect consistent decisions
Different rollout groups should not receive unjustified differences in eligibility treatment.
Include assisted channels
Where appropriate, test how frontline support and alternative access routes handle the new process.
Measure consequential failures
A low overall error rate can hide serious exclusion of a smaller group.
Provide remedies
Affected users need clear support and authorised correction paths.
Break-test: the new form rejects a legitimate nonstandard household
Can the agency identify the design gap and correct the case before expanding rollout?
